IMO, Ruby is a better Python than Python. It's simpler, has a cleaner syntax, and if you want to do funky stuff metaprogramming can allow you to do cool, and sometimes unspeakable things. Python has great library support, and slowness and Rails did make Ruby unpopular for a bit, but I would love to see a Ruby resurgence that wasn't to do with Rails, because it is truly a lovely language to use.
Hell, I would say that in 2023, it's easier/faster to get something set up and working in Rails than it is with frameworks like Symfony, Express, ASP.NET, etc.
Can you elaborate on the python part? I'm not a programmer ( I don't work in the field but I studied programming in high school) but I see python mentioned everywhere, is the language obsolete?
It’s not obsolete, it’s very good, still is. Just that Flask and Django both built on top of Python. So if it’s like late 90s or early 00s. Definitely before either Django / Flask. Python isn’t the new and thing of 2022.
Not a programmer but I think it's still useful for what I do. I've definitely not heard of it being very common in web design but that could just be because the use case is different.
It's handy in the same way PowerShell is handy, you can make a lot happen with it for general use purposes.
People who say PHP is shit haven't really used it and are just repeating the memes. It's a perfectly fine language and there are a number of excellent tools and frameworks for it. It's reputation is a result of it's easy entry and widespread use. A whole lot of people who knew just enough to be dangerous made a whole lot of stuff, and it ended up causing a whole lot of problems. But for some reason devs shit on the language instead of shitting on the devs who put them in a mess.
Nah, it's historically been a special kind of shit. It started life as a Perl templating engine, then grew out to its own language where it repeated all of Perl's mistakes while adding more of its own. Its community was single-handedly responsible for keeping SQL injection attacks in the OWASP Top 10 list for years. Notice that it's now bundled with "injection attacks" as a generic label for a wider range of similar issues--SQL injection alone would no longer warrant being there. Its conflation of arrays and hash maps meant it took years to wrestle with algorithmic complexity attacks. Perl kept the two separate, and was able to get a patch out for algorithmic complexity almost immediately (though it turned out to have a few bugs of its own, and a true fix came in a few years later; still faster than PHP solved it).
The web from 1998 through 2010 or so was absolutely riddled with bad PHP programs. "But that's not the language's fault", you say? Doesn't matter. Community is an important and underappreciated feature of a language, and PHP had a special kind of shit community. It almost seemed designed to suck away the dross from all other communities.
Consider the plugin system for phpBB:
Its architecture doesn't have any kind of hook system for plugins; they're added by patching the code in place
This naturally leads to different plugins interfering with each other
Having done that, you might choose one of the patch formats already out there, but phpBB decide to create their own
There are, at first, no tools available to automatically patch in plugins, so administrators (often not developers themselves) need to hand edit the source files and modify the database (the plugin format specifies both together)
Tools start to emerge over the years to handle it automatically, but they're buggy and unusable for a long time
Is it PHP's fault that one major application was implemented so poorly? YES! Its community is a feature, and its community is what brought us to this.
You want to claim that the language has done better since PHP7? Alright, that's fine. I still don't care. There are so many better options available, and I don't have time to keep up with all of them. I'm happy relegating PHP to being a long-tail language where it trails off slowly over the years like COBOL.
I'd say that PHP allows you to write very bad code (and makes that the default). It's a language feature.
For example Java has a lot of NullPointerException because it was designed with null and without mechanisms to detect & prevent these errors. Any method can return null and cause a NPE. It's just easy to ignore them. Modern languages like Go, Rust or Zig force you to handle null errors, and make it easy to do so. NPEs are a lasguage feature in Java.
In the same way PHP allows you to write any ugly code you want. There are no checks, no safety. People can write bad code, people can be lazy, people can be stupid. PHP allows it and empowers them.
I used PHP for the past year. And honestly I still think it is not a good language. Just of the top of my head.
By far the biggest culprit. Arrays. This monstrosity is basically everything. Yes, it is fast but it only teaches bad habits. It is a weird combination of Arrays/Lists/(Dictionary/Hashmap) and you can't know which one it currently is because there are 0 compile time safety checks. Also when used as a parameter it is passing a full copy instead. But the copy of course is only shallow. I have seen so many problems with that. And even worse when someone thinks the way to fix it, is to just json encode/decode the whole thing in order to get a deep copy before passing it.
Generics. I still don't get why this is such a huge issue. Like I would rather have a half-baked optional compile time implementation then none at all. The worst part is that IDE tools support generics so you end up inplementing them on the comment level. I shouldn't be forced to use generics through comments.
$ for variables. I know that this is just based on how the language grew. But god do I hate having to type it. It is not an easy to reach letter and just breaks my typing flow the whole time. You get used to it but still.
4 . The default functions. Yes. You will mostly use framework provided functions or your own stuff. But you still end up in contact with them and the naming schemes are still all over the place, so it is fast to just google it then hope you accidentally stumble upon it through the IDE. And some things are still straight up missing. Like the best way to deep copy an array is json_encode into json_decode. When I saw this the first time I was sure that must be wrong. But no. That is legit the way to do it.
Also I am stuck with PHP7 so some of my other complains seemed to be fixed in later versions. Also please don't recommend DS for my first issue. I tried to push for it but it got vetoed because "it is too complicated for new devs".
Not sure why you focus on arrays for deep copying. Deep copying objects is a problem in many languages and brings some challenges with itself that make it almost always necessary to delegate it to a library.
The language itself is not that bad. Especially the newest releases are really great, thought out DX improvements. What stinks are its legacy parts and how it needs to be run.
My biggest pain is that for it to actually behave like it should it requires some sort of an actual web server like apache or nginx.
Also, servers written in are actually request handlers - every time a request comes, the whole app is reinitialized, because it just can't hold its state in memory. In many apps every request means reinitializing connection with database. If you want to keep some state, you have to use some caching mechanism like redis or memcached.
Also had one time when Symfony app was crashing, because someone forgot to close class braces, and everything was "working" until some part of code didn't like it and was just dying without any error.
And one time when someone put two endlines after php closing tag at the end of the file, confusing the entire php interpreter into skipping some lines of code - also without warning, and only in specific php version.
$ for variables. I know that this is just based on how the language grew. But god do I hate having to type it. It is not an easy to reach letter and just breaks my typing flow the whole time. You get used to it but still.
I'm assuming you're not using an English keyboard..? Shift+4 is an extremely key combination for me lol
The answer for the deep copy would seem to be a combination of a static recursive function to copy the array while cloning the objects inside, with setting the __clone() magic function in your objects to break the references, no? Granted it’s not a built in function, but not difficult to implement.
There are a lot of people who think that if a language or framework doesn't completely disallow bad practices (and of course the authors have to agree with their very specific subjective ideas of what bad practices are) then it sucks. I've always found that weird. Like why are you mad at a tool for being "too flexible"? Why not be okay with learning what not to do?
If you're going to do that, then you also have to have a community that stresses best practices.
In 1999, Perl was leading the world with a tutorial for DBI (its primary database driver interface then and now) that uses placeholders in its very first code example. The community made that the standard, and it was the first hit on "Perl SQL tutorial" on Google for a long time. Perl applications with SQL injection attacks are out there, but have been relatively uncommon.
Notice that the API doesn't force you to use placeholders. It's simply strongly encouraged by the community.
Also in 1999, PHP was leading the world in not having a database driver interface through a common API, but rather a thin wrapper over whatever C libraries were used for individual databases. If that database supported placeholders at all (MySQL didn't, and guess which database was most popular with PHP?), then it often had a different syntax* for every one. (Note that Perl's DBI uses a translation interface that can implement "?" as a placeholder for you if the underlying DB doesn't do anything else or uses weird syntax). You could always use a filtering function, and PHP devs would routinely try to write their own rather than use the one that came with the database API that's already vetted. Either way, there was no widespread community pressure to use safe practices, and PHP led the world in SQL injection vulnerabilities for well over a decade.
*As a side note, I was recently accused by another dev of having a Python app riddled with SQL injection vulnerabilities. In fact, it was well protected, but it was using the psycopg interface to PostgreSQL, and it has a weird placeholder syntax that the other developer wasn't familiar with. Thanks, psycopg!
It has also improved a lot in the last years. PHP5 and especially versions older than that weren't very good and deserved a lot of the criticism. PHP7 and onward are much better languages and don't deserve the hate.
I worked a lot with PHP3 and 4, they work by the "Here is a flat C style API and here's all the functions to use." principle, and a lot of the work was finding the needed function, and how to use it.
I know PHP5 did a lot of redesign especially with classes, but have never used it, hope PHP5+ feels more like Pythons toolbox.
If I should write a web application today, I would start looking at Python based frameworks: Django (I have used it before)/Flask/Etc. as I am not sure I would like to work with JavaScript, or have to re-learn PHP.
I used to think that php was a bad language until recently (used php5 when i was just learning to program, cooked some delicious spaghetti). But after 5 years I had to use PHP at work. The language has improved a lot, but I think a lot of the bad parts are still there.
Like, why does stdclass exist? Why not just use associative arrays? Why are there warning, error, fatal errors, exceptions? Some functions throw exceptions, other raise errors, others return false, other fail silently and you have to call another function to check if there was an error (last_json_error). Why do find functions return false instead of -1? Like every other language? Why can't I use strings with numeric values as maps keys? (I can't have ["001" => value], it gets casted to ["1" => value].
There are no generics, you have to use mixed everywhere. The stdlib is an inconsistent mess, some_snake_case, someCamelCase, verb_noun, noun_verb, functions are not namespaced, everything is global. A lot of duplicates: die vs exit, print vs echo, etc. You are forced to use PSR & autoload to be able to use namespaces in a tolerable way, not including_once everywhere. No UTF-8 support, only ascii. You have to manually use mb_ functions. Variable scoping is weird. Variable variables? Why?
And all that is just comparing it to the average language. If compared to a modern language like Rust, Zig, Swift, php is light years behind.
It's not hot garbage, but I wouldn't call it "good". There's laravel, but not much more. PHP still makes you shoot yourself in the foot by default, unless you spend a lot of time learning its edge cases. Just like javascript.
I think the worst thing about PHP is all the ancient tutorials that litter the web like landmines. SQL injections everywhere.
And there's way too many low-budget wannabe web developers who know just enough to blow their own feet off. Or more likely whoever paid for its feet, because that web dev will be nowhere to be seen a week after handing it over.
Honestly, php is actually pretty fucking sweet for functional programming and metaprogramming... other languages wish they had __invoke and __get.
I also think it has the "right" balance of library functions built in, you can do pretty much anything common and trivial with built-ins but the function list is short enough that you can comprehend most of it.
__invoke is just for making a class Callable. Java has those with functional interfaces. __get is just dynamic property resolution synax sugar. Instead of something like obj.get("property") you do obj->property.
Instead, I would like to see ADTs, generics, pattern matching, immutability, expressions everywhere and a better stdlib. Then one could call PHP functional.
It's like how people say Javascript is functional. Sure, it has lambdas, anonymous functions, closures, const. But those alone don't make it functional.
Functional programming is very different (and at times hard). If you have the time you can check out F#, OCaml, Elixir, Erlang, Rust or Haskell (in order of difficulty imo). Those are more "pure" functional, rather than imperative/OOP with a touch of functional.
See how things work, what features they have and don't have. How problems are solved in these languages. I think learning about one of them can give you a different perspective on what functional means. I discovered F# one day, got curious and discovered a whole different paradigm, a new perspective on programming. And learning about functional programming really made me a better programmer, even on procedural/OOP.
It's also funny how they mention languages and frameworks, but php is just php. No symphony or whatever people use now, php. And somehow people whlent from using frameworks in python to not using them? It makes little sense.
I think PHP is shit because I used it about 14 years ago (+/- 1/2 years), where it was crystal clear that the language was written by a complete amateur. I've example off the top of my head: you couldn't reference an element of an array returned by a function in the same line, you had to first assign the function's output to a variable and only then were you able to reference an element of the array in the variable. Like, WTF!!!???
It may have improved over time, I just don't care enough to find out. It doesn't deserve my attention.
If you're thinking of PHP version less than 8 you need to have another look
Totally stateless. Uncached server side rendered response times in double digit milliseconds.
Types
Extremely battle, highly tested frameworks.
Excellent tooling for tdd, bdd, static analysis, automated browser testing, coding standards and auto fixing. Even fully automated refactoring for things like package upgrades (Rector)
Regular, solid, releases bringing updates and fixes
Arguably one of the best package management systems, Composer. And only one, none of this constantly changing tooling that some other ecosystems seem to do
Properly open source platforms to power all kinds of web projects from e-commerce, CRM, social, scraping, analytics, monitoring, API, CMS, blogging
Basically if your target is server side web stuff then it's really good
Or, you can continue to demonstrate how out of touch you are by continuing with the old "PHP bad" jokes if you want!
not only that but you just install it with the lamp stack setting in ubuntu tasksel with apache and mariadb. the beating that these can take (except maybe the sql) and survive is great. you also have access to the whole of linux to do more advanced stuff, while other languages/ stacks shy away from exec
All of that can be the same as other stacks except the Apache bit. You can stand up a Go application on Ubuntu hitting MariaDB as its persistence layer. Or Python. Or Node. Or Java. Or even Ruby. Shit, Haskell can do it.
Also, exec is a code smell. Arbitrary code execution is a massive security risk, and the effort to mitigate that risk is often less than explicitly building out the required functionality.
I think you need to explore more technologies, my friend. And read up on some security things
Edit: I now realize you mean exec as in calling out to a shell. All languages have this. Still, the overhead of spawning and managing a new process is often more than just implementing the logic in your application itself.
It's hard to justify using anything other than JS or if you wanna be fancy, Web Assbly, for the FE.
Any other front end language involves generating Javascript from your language, which inevitably ends up with you making a weird Frankenstein project that mixes the two.
I'd rather just use stuff like Webpack or Vite to compile my JS front-end out of JS (or TS) from the start. It always ends up being a cleaner result.
My backend though can be whatever the fuck I want it to be.
But if you ever think dynamically compiling/transpiling a JS front end on the fly on demand is a good idea, instead of simply just delivering static pre-compiled/transpiled pages, you're part of the problem for why the web is so slow and bloated.
It's wild how crazy of projects people will build that take 3 entire seconds to just deliver a 500kb static form that doesn't even need angular to do anything. They turn a couple hundred kb into several mb for no useful reason, it's wild.
But yeah, I mostly blame the project managers that encourage this behavior, it's wild how much overengineering goes into basic stuff like making mostly static websites.
To my understanding, you can't really use WebAssembly for the frontend - it doesn't support manipulating the DOM, so you still need to offload a lot of the work to JS. It's an uncontested language when it comes to web frontend.
It does support it, it's just slower than JS. WA is faster in other aspects though, so frameworks that compile to WA (like the Rust framework Leptos) still end up being faster than a lot of JS ones.
I find that the only reason for SSR existence is to be able to just move a JS frontend to the backend for SEO/client performonce reasons with almost no effort. If the frontend really needs to be highly interactive then yeah, a FE framework makes things easier. But then you are locking yourself to using JS in the backend. Voluntarily locking yourself to use an objectively bad language.
Then there are the react/angular/other people, who build everything in these frontends.
I really hope tools like htmx gain traction, since it looks like a model able to solve the current JS madness.
I'm not liking htmx, I checked it out, it seemed promising, but it has giant gaping security holes in it so I can't endorse it.
I have been sticking to using Ejs with html-bundler-webpack
The combo is lightning fast and gives me a solid usability of html partials so I can modularize my front end in re-useable chunks.
It compiles to the static site fast for iterative development, it has everything I need baked in for common needs (minification, bundling, transpiling, cache busting, integrity, crossorigin, tree shaking, etc etx)
I like how it let's me just focus on actually writing the html + js + css and not have to muck around with thirty boilerplate steps to just make the app run.
If I need a lot of reactivity I'll use vue or angular but I so so rarely need that.
And now with the template element, half the time reactivity can just be done with those.
Only time I actually need react/vue is when I have to frequently mutate/delete in the DOM.
But if I purely am additive, adding things to the DOM, template elements are plenty.
This was nearly a decade ago. I worked at a small app company (5-10 developers) for a bit that used Ruby on Rails for our product. The product was in active development, but was available to customers so it was “done”. We were hiring a senior level dev to oversee the team and we interviewed this guy (maybe in his 40s?, a but older than most people in tech) and he said his first order of business if hired would be to refactor the entire code base to php. I don’t think he was joking. I’m not sure why he interviewed.
Were people saying PHP was dead in 1995, the year it was released? I guess maybe?
But who was suggesting abandoning PHP for Django in 2003, two years before the latter was publicly released? I suppose the person who made this must've read that Django development started in 2003 and gone with that; most of these years correspond with when the respective project started.
So, the reason Perl (which remained more popular for web development than PHP or any of these things into the early 2000s) isn't on the list must be because it actually predates PHP.
I'm sure there are a lot of reasons why PHP is better than Python for the backend, but I created an app wirh Symfony 5 and then an app with Django 4.
Symfony is so weird compared to Django. With Django I can just sit down and get things done. Symfony always seems to have some quirks which are mostly due to PHP (and me not knowing how to program in PHP).
That said, PHP hosting is so much easier and cheaper, this probably is important for smaller projects.
Many older projects don't get migrated to containerized infrastructure and smaller businesses don't want the overhead it creates to run a single app/webpage. Plain LAMP with FTP access is still the most common way to host I think (and thus the cheapest if you consider the amount of work that would need to be invested to containerize).
Lets just say that Python was a language that was never supposed to be used for anything production related. PHP's memory management and multi threading capabilities are WAY more solid and less prone to leaks than Python 's.
As someone that used PHP professionally for literal decades, the PHP hate is so meme-y.
Its biggest problem is that it allows you to do some truly cursed things. The same can be said about other languages, but PHP really doesn't do much to set you up for success, especially as a new-intermediate coder.
With opcache, it became fast enough for basically most web backends, and as a language overall it does seem to be evolving and shedding off some of the crap that used to make it truly horrible in the hands of a new person. At least the type-juggling stupiderrors
Now I mainly use go and python (only because I have to on this one), and I would put Python and PHP on a similar level of "fuck this language" moments
For the backend? Why? I could see PHP being better for the front end considering it's basically a templating language already, and setting up Python on a webserver is much more complex, last I tried.
On the server-side PHP is used by 76.8% of all websites (a large chunk of that being WordPress). It is not going anywhere, soon. Looking at this statistics, nothing else seems to be even in the same league from a pure usage point of view.
I have yet to see a reason why it should change. Serious question: What is the disadvantage of using the tried and tested PHP8 compared to the alternatives, if you already know PHP?
Serious Answer: PHP in itself is not that bad, despite some discussable decisions in function naming and arguments order to name a few. The biggest problem, is that it has a settings file describing how it works (php.ini) and that sh*t will bite you in the rear when you move apps from server to server, where all the libs are different etc...
PHP never works out of the box when moving something on a new server, that is the worst part of the language.
Maybe the issue in your example isn't related to "how bad PHP is" but is to "how bad the code you're referring to is". Never had those kind of issues and yes obviously you've to know what extensions an application is using, but once again, modern PHP applications usually use composer as dependency manager and will gave those specified inside the project.
Easy example. Have they fixed file upload behavior yet? Do they store the entire file in memory by default instead of chunking it and storing it as it comes in?
If not it's like the worst memory usage of any language possible.
If you have to go change the php.ini to adjust file upload sizes, it's not really moving forward and is decades behind other languages.
File upload behavior is actually determined by your web server (unless you're launching PHP in listening mode) so apache is probably who you want to blame here.
Easy example. Have they fixed file upload behavior yet? Do they store the entire file in memory by default instead of chunking it and storing it as it comes in?
Are you in 1995? PHP dynamically decides how to manage uploaded files, it will generally store a few MB on RAM and move it to disk after that point. It also support streams so the backend can take the incoming data live and do stuff with it without storing it first as usual in the classical model. There are also plenty of higher level solutions to deal with chunked uploads, mobile clients disconnecting such as https://tus.io/ that are used by large companies like Vimeo.
Poor performance, execution model limitations, lack of static typing (although they seem to be working on that), and general legacy cruft.
Don't compare PHP to Node, Ruby or Python, they also have problems. I think Go is currently the best choice for a web backend; an objective evaluation of PHP and Go would certainly put Go ahead. If you know PHP, you can pick up Go in a day or two, so I don't think that's a great reason to keep using PHP either.
Usage statistics are a highly misleading, software projects take several years to develop and a majority will fail. Looking at current usage tells you the most popular choice from 5 years ago, not today. Over 90% of video games published in the last 5-10 years use Unity or UE4, but these probably aren't the best choices today.
I think Go is currently the best choice for a web backend; an objective evaluation of PHP and Go would certainly put Go ahead. If
Yes for performance running code, for performance as in "developer time" PHP is way faster. Go is solid but developer take more time implementing stuff with it. Use PHP for everything business related except for that one or two cases where you really need the performance that Go provides and where it is worth the extra dev time.
The PHP I've once used is probably not even remotely close to the PHP people use today. The issue is, once you lose the trust and confidence, it's hard to gain it back. All the people who consistently shit on PHP have also probably not tried it in a very considerable amount of time
django and flask are python btw and people wanted to learn python or perl from like 15 years ago, the popularity of python 2 and its "Issues" led to robust dev on python 3, not to mention it being a default for many linux distros since a long time ago
Languages don't die. That's a misnomer. They have long tails of diminishing use and no junior programmers entering the space. If you're one of the experts in the language left around, you can make a shit load of money.
And the jobs are rarely worth the stress of picking apart the terribly designed, chock full BizDev rushed ads-on features due to foolish promises, and a manager that's stressed out due to how few experts they're are that's going to try and micro-manage you because his skip-level is breathing down his neck about when something is going to be fixed.
Not sure if it was the first, but PHP still beats a lot of other "platforms/framework" because thats what some of these items on the list are in terms of ease of embedding code directly into what you see what you get frontend code (HTML). It inserts backend code into HTML like javascript and that was very convenient and easy to learn, still easier than figuring out some of these platforms different templating shortcodes, that and its constant development and community support. I used to live on the PHP docs comments.... it was a great community.
That's possible with some java frameworks, no? The "insert code into the html file"? I remember doing that in college (~2010), but I don't remember the framework we used
It was released in 2004. I had a co-worker who was hugely into it in 2005. Entirely coincidentally, he was also into absurdly overcomplicated code and clusterfuck projects that failed after years and millions of dollars.
He was also the only programmer I've ever known whose code literally nearly killed a child.
PHP is a shit language, but far from dead. There are too many legacy killer apps that are used A LOT and won't be rewritten in a different language anytime soon. E.g. Wordpress, Mediawiki (The engine behind wikipedia and other wikis), Nextcloud, Typo3, ...
