That said, I don't think that strategy would be viable, for a couple of reasons. 1) It assumes a strong correlation between "code was written in <2010" and "the QA process is crap", and likewise between "code was written >2010" and "the QA process is pretty solid." I strongly suspect that correlation is a lot weaker than you make it out to be. The really-old public projects I know (I've worked on Drupal and TYPO3 cores personally, both of which are 20+ year old code bases) have pretty solid test coverage now, and ample QA processes around them. They're possibly tedious to update for deprecations et al, but not per se hard. In contrast, I now work with some 7.x-era Laravel projects that, well, "get the QA tooling out of the stone age" was the first task I took on when I joined the company because they desperately needed it. I don't think "it's newer so the QA safety net is in place" is a safe assumption. 2) The vast majority of issues that need to be fixed are the old stuff; most are from PHP 4 or PHP 3, so we're talking pre-2005. The features introduced from 5.3 onward are, for the most part, pretty reasonable. (Not perfect, but way way better than the PHP 3-era stuff.) So "you can only clean up recent messes" translates to "you can never clean up a mess." 3) There can absolutely be code written in 2020 that relies on the current behavior of array_sum, or $string++, or passing null to strlen(). Some of it has been mentioned in this thread. So "only old code relies on old, bad language design decisions" is not
Re: [PHP-DEV] Future stability of PHP?
I generally come across 3 types of projects: 1. Projects that were originally developed a number of years ago and have not been updated since 2. Projects that were originally developed a number of years ago and have been updated regularly since 3. Projects that were originally developed in the last 5 years and have been updated regularly since Interesting categorization, especially the 5 years part. Looks like I misjudged the magnitude of the shift in the PHP community a few years back (not just from your categorization, but from what others wrote as well). I think of languages as tools specialized for a given problem space. Even general purpose languages have a lot of design decisions that make them better suited for specific areas than others (e.g. memory management, threading, scripting, …). And usually there's some spillover of thought patterns from one language community to another (e.g. someone programming Java in PHP, JS in Ruby, C++ in C). I thought those spillovers were merely affecting the language design a bit more than usual. After all if I want a statically typed language there are already ample to choose from. But this was clearly the wrong mindset on my part. I usually combine various languages in a project, mostly depending on whats already part of the environment, well maintained and stable. So my focus is on when to combine what tools and languages. But from your post and others in the topic most (if not all) seem to work on larger code bases mostly focused on PHP. And in this situation it makes more sense to bring static typing into the used language. Thanks for clearing that up. Generally projects in 1 match what Stephan described: My usual tool set for web projects like that is plain PHP, HTML, CSS and JS. Everything without any frameworks or unnecessary libraries and kept as simple as possible. If possible I just use builtin and stable APIs and usually end up without any or with just one or two dependencies (e.g. PDF generation). I've tried to keep this generic, but in a lot of cases I see this with local government work that was developed several years ago (generally PHP 5). They had budget up front to build something but then expected to maintain it without any code changes, just by updating the OS and PHP. They perfectly match Stephan's use case group: I think a lot of programmers underestimate the flexibility and simplicity of file based webservers like Apache with PHP. If you keep it simple they allow projects to grow organically. A lot of that are just small projects, small customers or the inglorious everyday work that nobody likes but someone has to do. So it doesn't get talked about much. These tend to run for 10 years plus. I haven't worked on any government projects, but I guess industry and process automation isn't that different (maybe a bit less bureaucratic). Machines run for decades and I guess this also sets the time-frame or mindset for the software used in there (ERP systems, CRUD-like stuff that models small processes, etc.). Maintenance of course is part of the picture but on the software side admins are expected to take care of that. Actually changing code to keep it running as-is isn't expected, and of course this shapes budgeting. Except for the industry 4.0 subculture, that seems to be a totally different set of people. But I have no idea if my experience is representative of the industry. Most of my experience comes from companies in the range of 100-200 employees (with maybe 5 IT people) or smaller. I've used PHP in such environments several times, funnily enough because it was the preferred option for the admin. Maybe the budgeting is my hint that I shouldn't do that again. Apart from that I often employ a way of programming that seems to be quite different from what other posts describe. I usually optimize for minimal complexity, minimal dependencies and maximal stability. Taking advantage of the environment to reduce the number of moving parts where I can. You could say I hunt for synergies between tools to avoid complexity. This often means taking a bit longer at the beginning or sometimes using weird tools because they're already an indispensable part of the environment. A classic is letting an already existing webserver handle authentication via LDAP or Active Directory. It pays of in the long run with low maintenance overhead. It's not zero, bugs happen, stuff changes, but it's maybe a code change every few years instead of every few months. For me this is just another way to write software. It works in some situations, it doesn't work in others. Since my projects are usually to small to justify a team of programmers I end up using it quite often though. Also almost all of my projects are one-off "built something that does X in our environment" things. Not evolving products that get regularly extended (I have just one of those). Hence its difficult to piggyback

Lack of PHP support from vendors is a strategic problem for future ecosystem health. There will be multiple reasons¹ vendors will choose to support other languages and not PHP, but one certainty is it means funded startups are not putting their cash towards PHP. For users of PHP, when we look at using a 3rd party service, I would imagine most of us don't price in the cost of building, maintaining and supporting our own extension. The outcome would be to not use the service - or to change language to one where there isn't this friction. Needing to write an extension to be able to build your app on top makes the platform behind before the race is even started. ¹ I am interested to find out what their reasons are. Why don't companies choose to make PHP extensions? Is it that PHP is inconsequential to them, the perception that PHP users are too small an audience, difficulty of creating the extension, or other reasons?

Tools like PHPStan and Psalm can do a pretty good job of finding all dynamic property usage for you, without needing to write a test suite for it. They'll treat them as an error, but it should give you a good sense of where to add the attribute. It won't be perfect, but it will probably catch the lion's share of them unless you're doing very dynamic things.

RE: [PHP-DEV] Future stability of PHP?
Essentially the same thing here. Removal of dynamic properties will be the next big one for my team. It's the deprecations that hit huge swaths of code without really offering much benefit that are annoying. Yes, we have a _lot_ of classes. Also multiple versions of Zend framework that we backport to. However, I see in a subsequent email that this is in preparation for improvements, which makes it more tolerable. To clarify; Are you saying that you have a _lot_ of classes _which make use of dynamic properties_? A class where properties are predefined is unimpacted by this. stdClass is also unimpacted (as it implicitly has allowdynamicproperties). The only classes you should need to add the attribute to are ones where you're using them, essentially, as typed associative arrays. I'm surprised if that's what you have, because it seems like a lot of extra effort to give names to what are essentially anonymous structures. The advantage of providing a name should be that you get to know what properties will be present (and perhaps that the values therein are validated or typed themselves). Can you expand a bit more on your use-case? We have a lot of classes, a small portion of which use dynamic properties, but we do not necessarily know which ones do. It’s different than, for example, a change to the count function. We can search for all instances of “count” but not for dynamic properties. I’m unsure if it’s practical to run deprecations on in prod and our test suite, although substantial, doesn’t cover all code paths. I’d probably summarize our use case for dynamic properties as “old codebase and dynamic properties were OK”. Our system was originally in Perl, so the initial dev team probably felt at home with dynamic properties coming from Perl objects. But again, after reading others’ comments stating that this is part of an effort to improve some aspect of PHP classes, we can live with the change. I was recently looking at the Perl 5.x repo and was surprised at the amount of activity. There may be some small takeaway (like, literally a small takeaway, not in the “small meaning big” sense) in how the 5.x community has seemingly flourished, especially considering the failure of Perl 6. -Jeff (and I apologize for the mauled quoting...

Re: [PHP-DEV] Future stability of PHP?
> Can you expand a bit more on your use-case? Here are some things I've deliberately used dynamic properties for: - development proxies (production uses compiled proxies) for remote objects [can use attribute or magic functions] - visitor pattern when hacking on parser packages [in PHP 9, "hacking" will be more complex if underlying package doesn't support dynamic properties] - "tagging" objects [can use weak maps now] - deserialization of user-submitted types to a base class [can just 'decorate' a stdClass] In brackets, I listed the 'solution' for avoiding dynamic properties, but FWIW, having dynamic properties available made it far easier to create 'POC-style' code that could be refactored/rewritten. I personally never saw a bug resulting from dynamic properties, but I might have just been lucky. -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: https://www.php.net/unsub.php

Even in this case, however, the stdClass specialization would have dynamic properties implemented in a way which would allow an escape hatch for user classes via extending stdClass. We wound up with the attribute approach instead, which means that the logic for dynamic properties, as well as the allocation overhead, still has to exist in all userland classes. All approaches however, came with stdClass working as expected out of the box, and a low-effort, forward-compatible escape hatch for those rare cases where dynamic properties are needed on custom classes.

Removing dynamic properties has multiple benefits - from avoiding typos/mistakes (which before were completely silent) from being able to refactor objects in PHP in general (after PHP9) to be more efficient. The RFC (https://wiki.php.net/rfc/deprecate_dynamic_properties) details those benefits quite well, if there were no benefits it would hardly have passed. This is one of the no-brainer changes for me, as the upgrade path with the attribute is so easy and there are so many benefits. -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: https://www.php.net/unsub.php

We run those "on" in our dev and QA environments but off in production. I'm referring to the work required to mitigate the removal once we plan to migrate to 9. Although our codebase is old, we are funded to keep the code up to date. It's just that a handful of the changes, such as removing dynamic properties, has such a large impact and such a questionable benefit. It's only a tiny portion of the language changes, though, and I mention it just for awareness, as we are **VERY** appreciative of the work everyone puts into the PHP project. I know it's a thankless task. -Jeff

Disclaimer: This quote is taken out of context, the original message can be found here: https://externals.io/message/110936#110937 As I've mentioned here before, I've seen a few folks bring up the message that I see on this quote as: Voting rights are not necessary to contribute to PHP Internals. PHP is an extremely large ecosystem and bringing community/user voices to internals can greatly help developers understand how the language is being used and how proposals can be shaped to help address concerns that are made aware. I'm not voicing my concerns in the hopes of making my problems your problems and that the PHP core developers should fix it for me. I have been going through a rewrite for the last 6 years and I expect to be done with it in the next 5. Every year we need to go back to the legacy spaghetti and upgrade it for security reasons. It's busywork and adds no real value to us. We still do it and we will keep doing it no matter what. But in the course of doing so, I lost coworkers to Typescript with a reasoning that it doesn't make sense to rewrite our product in a language that will keep breaking the codebase constantly. I'm not here to discuss the merits of their decision because if I 100% agreed with that decision, I wouldn't be here, I would be long gone and developing Typescript fulltime by now. But in my little bubble, losing highly talented PHP developers to Typescript has been a recurring situation and that loss of community members saddens me.

Maybe this is not new information to any of you here and there's nothing that can be improved on it unless someone drops 8 digits of money on the PHP project. Maybe that is a price that PHP has been willing to pay to keep on doing what it currently is doing. Or maybe there are some interesting things that can be taken into consideration. Do what you will with my participation. The only expectation I had when I joined this discussion was respect and that was almost completely met. -- Marco Deleu
Re: [PHP-DEV] Future stability of PHP?
> I'm saying that the DX for writing extensions is better in other languages. Citation needed. Java's extension API is certainly a hot mess. Python's is fine, but ultimately has similar pitfalls to PHP's. Go's looks very nice at first blush, but given that it's closer to an FFI than a proper extension API, shortfalls inevitably show up when you try to do anything complex. I'd also point out that PHP's extension API isn't stagnant. The stub generation improvement of just a few years ago significantly improved the process of writing extensions. > And that these days new products come along and provide extensions for > other languages but not PHP.

That you can take two things and smush 'em together because you need something from both. > PHP now has FFI which provides an easier way to extend PHP. I have huge > hopes for it - but in my experience it doesn't feel finished. I agree, it's not finished. But the problem there is also the opportunity. OSS works best when people who have an actual need are the ones designing the interfaces and making things better. I don't pay attention to FFI because I can write PHP extensions on a my mobile, while sitting on an island beach and playing board games (true story). I know that's not universally true, but it's why I'm not putting the effort in, because I'll end up building the wrong solution by not truly understanding the requirements (also a true story, take a look at streams sometime). If it feels like FFI is stalled, it's probably because it's "good enough" for the people who got it to this point. The itch is scratched and the need is met. So when I call the state of FFI an opportunity, I'm not saying "code or gtfo" as such is sometime vilified. I'm saying this is an open source project of the purest kind and it really is up to someone to care about a thing enough to put in the work to make it better. And if your reply is, "But I don't know C", then good news! That's another opportunity. PHP is a nice language, but it's not the only one out there. C is a mother language, the payoff on learning just keeps coming around. -Sara -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: https://www.php.net/unsub.php

Re: [PHP-DEV] Future stability of PHP?
Just to follow up on that, and going totally off topic, I was reading about thanks.dev the other day. One of our concerns is that we can easily give money to top level projects or things we consciously add but how do you give it to all the dependencies and the thanks.dev approach seems a good idea (I have a separate problem in that our projects are rarely on GitHub or GitLab) but does anybody who would actually benefit from it have any thoughts on whether it would be good for them or not? > On 11 Apr 2023, at 10:09, Matthew Sewell wrote: > > What's meaningful in this sense? > > I have a budget for supporting open source projects (back to my money v time > point) and a percentage of that is for the PHP Foundation.

What's meaningful in this sense? I have a budget for supporting open source projects (back to my money v time point) and a percentage of that is for the PHP Foundation. I'd happily pay LTS fees we pay elsewhere (even sometimes as a safety net) to the Foundation but believe that the money we give to projects is just that, a donation that the project can use as it sees fit, rather than the purchasing of a service as we do commercially.

Re: [PHP-DEV] Future stability of PHP?
Hi, This is a really interesting thread and am glad that Stephan raised it as I've been thinking along similar lines for a while now and am glad I'm not the only one. Considering the range of people adding comments (especially someone like Mark) then I would hope everyone agrees that this deserves a full discussion (though am now concerned by a couple of Larry's comments that I've referenced below). If I may though, I'd like to take it back to Stephan's original point as I feel there is a bit of digression (though some is really interesting). I generally come across 3 types of projects: 1. Projects that were originally developed a number of years ago and have not been updated since 2. Projects that were originally developed a number of years ago and have been updated regularly since 3. Projects that were originally developed in the last 5 years and have been updated regularly since Generally projects in 1 match what Stephan described: > My usual tool set for web projects like that is plain PHP, HTML, CSS and JS. > Everything without any frameworks or unnecessary libraries and kept as simple > as possible. If possible I just use builtin and stable APIs and usually end > up without any or with just one or two dependencies (e.g. PDF generation). I've tried to keep this generic, but in a lot of cases I see this with local government work that was developed several years ago (generally PHP 5). They had budget up front to build something but then expected to maintain it without any code changes, just by updating the OS and PHP. They perfectly match Stephan's use case group: > I think a lot of programmers underestimate the flexibility and simplicity of > file based webservers like Apache with PHP. If you keep it simple they allow > projects to grow organically. > A lot of that are just small projects, small customers or the inglorious > everyday work that nobody likes but someone has to do. So it doesn't get > talked about much. These tend to run for 10 years plus. Projects in 2 are the trickiest. They're often projects that were started in PHP 5 (or in some cases even 4) and have been upgraded over time. They're generally well maintained and structured code bases although don't have full test coverage. For these the upgrade to PHP 7 took a lot of planning and effort (and some of them have been my projects since the beginning so unlike the others I can't always even blame other people for most of the original decisions as they were mine 15-20 years ago! ), though that was unsurprising given the context, but that process then needed to be repeated for PHP 8 (as previously mentioned, null handling was our biggest issue especially as we couldn't change our integrations with several hundred partners). Projects in 3 are generally modern PHP applications, often using frameworks. They tend to be the easiest to maintain and upgrade as they're written as modern applications with full test coverage. Once you throw in the business processes around upgrading though they're still not as easy as is being suggested in some places here :) As Andreas said: > The PHP ecosystem even just in the last 10 years has changed completely, with > composer, more mature frameworks, easily usable independent components and > even static analyzers. For me that ecosystem is the big value proposition of > PHP, in addition to a good standard library. Does this mean that projects which use the traditional PHP approach (i.e. without the complexity) are now not considered a good fit for PHP? Back to Stephan's original question. Is PHP still the best use case for type 1? A long running, simple application that doesn't use Composer or a framework that can be extended slightly over time? If the answer to that is no then so is the answer to 2. In our case the projects in 2 are generally static because they're critical and therefore have budget, though haven't been upgraded to entirely new applications as they're overly complex, integrated with multiple partners or subject to legal regulations. Is PHP still a suitable language for building a long running, complex application that needs to be maintained for 20 years plus? The issue with this is more to do with the frequency of breaking changes? Following on from that then I had some other thoughts and questions. I'm not suggesting that the issue isn't that there weren't warnings, and that deprecation notices weren't in place. The issue wasn't that we didn't know that the changes were coming, but that we had to make them. As Ilija said (and his opinion is obviously very relevant): > Sadly, there's a conflict of interest here. There are people who want to keep > running their existing websites without having to make any changes, and there > are people who are using PHP daily and would like to see the language evolve. > We would like to satisfy both of these groups but that is difficult when they > are often directly opposed.

This is the failure of the business owner to plan accordingly and ignore all the warnings for years and decades. That is if any developer raised any concerns lately, which I also have seen quite a bit when "yes man" just shove code into the meatgrinder for a year or two and then just move to the next job: "It's not my problem, the next guy will deal with this". And that feeds the vicious cycle, and the owner is either oblivious or does not understand the implications because "well, it works, it generates money" at the moment right until that plane hits the ground and things blow up. I've handled a big legacy project, did major updates to it, seen how an effort of 1 month of my time to drag it into the modern day paid off over the next 6 months by picking up development speed by 3x with the same team of 5 people + me. In 1 year we started to literally take away clients from our competitors who could not keep up with us and we had a literal line of clients to onboard, we had to scale our sales team 3x and had a backlog of 6 months still. All stemmed from a single decision "I will tackle this, we need it to update to newer PHP". Business owners were really stoked that they actually listened to developers. You cannot expect to run code that was written 2 decades ago without major updates on modern language versions. It's not possible for almost any language that is being actively developed. Think laterally - instead of hand-fixing every null check out there, introduce a library that can handle data structures and handle the nulls for you en mass. Isolate the internals and just pass already sanitized values into it. Suddenly you cut off like 90% of the needed fixes that prevent you from running your code. It's still needs fixing, but at least you give it good data to start with, so it does not error out. -- Arvīds Godjuks +371 26 851 664 arvids.godj...@gmail.com Telegram: @psihius https://t.me/psihius >>> >>> Thanks for your reply, I understand everything you mean here by >>> improving a development flow.

But it also can usually be done in chunks - most systems only seem like monoliths, but they aren't really. I've literally headed a re-write project with a team of 4 at a company that was barely 20 people total. So I will never take the argument "only big companies can do that" as a valid one. If anything, bigger companies have a far more higher failure rate because of bureaucracy, internal politics and your typical corporate backstabbing. > > > >> Telling them that the debt collectors and lawyers are here isn't going > >> to help them when the people that pay them so they

Let's suppose that we were 100% certain it would pass with 100% approval. However, if someone is doing something screwy and buggy it will change the behavior by making previously-kinda-working-but-definitely-buggy code throw a Warning, and later another oddball usage will throw a deprecation, and then eventually in PHP 9 a TypeError. Perhaps not the best example. There's definitely some cases that need cleaning up; but deprecating inc/dec for anything but numeric values is IMO too extreme in what it proposes making it little more than syntactic sugar for the += and -= operators, only working with numeric values. https://wiki.php.net/rfc/saner-array-sum-product might be a better example. -- Mark Baker -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: https://www.php.net/unsub.php

So am I expected to stay silent when I see potential problems with bc breaks because I should just be grateful? Almost all other languages have deep pockets behind them one way or the other. Frankly, they can afford it. PHP has no such option. So, in some way, yes, sometimes you just have to take the loss and move on. PHP has to prioritize the resources and relies on what people are interested in doing for the project. Historically PHP just can't maintain lots of legacy stuff, nor have long LTS releases - that's why there are only 3 versions of the engine ever supported at the same time. That does not mean that I should stay silent when I see problems; nor do I intend to. This is business. Adapt or be swallowed by competitors. This really has nothing to do with language development. 2 decades is enough for a commercial entity to realise something needs to be done about the code base. Speaking of competition - PHP needs to move forward at a pace where it stays competitive with other languages too. The project has already stumbled once, that's why the RFC process and yearly release cycle was born. Because that thread was identified and people decided to do something about it. I've not mentioned 20 years; but business application should have a lifespan longer than a mayfly. Even 3 years feels too short for companies that have a lot of apps that need to be maintained alongside new development work. Not every company has enough developers for dedicated teams to handle upgrade work full time. PHP 8 was released 2.5 years ago. To be frank, I have a feeling that the code base in question is never going to keep up with PHP even if it does 1 release every 2 years. The result will be the same. In my case, on multiple occasions, the management just decided to sunset the old systems and just build new once on modern code bases with modern frameworks, libraries and using all those bells and whistles like Psalm, phpstan, cs-fixer, run modern development practices. Some people left, new people got hired. Business moved on to have far more sustainable software on their hands that underpins it's whole existence. Most clients I worked for who clung to their old systems at this point are all defunct. Because competitors just ate them up eventually. Rewriting any system from scratch can be a major undertaking (I do know, I've done this myself, and it took a team of 6 people over 8 month in the most recent case). It isn't the type of undertaking that can be taken without considerable investment. Yes, the new system was written with all the bells and whistles; but upgrades still take time and investment, and there's still the demand for new features. No companies but the very biggest can indulge in that on a regular basis: developers are there to add value with new features, not just staving off technical debt. Telling them that the debt collectors and lawyers are here isn't going to help them when the people that pay them so they can eat and have a roof over their heads and care for their families is a slap in the face to them when they are torn between business demands and wanting to do technical upgrades. The point I was making is that at that moment it's too late to do anything. That's when you close the business and hope you are not in the red. And that's tough on the developers that have been struggling with those legacy debt issues alongside trying to keep a system running and making money for their employer. When the business closes, it's the developers that suffer, not the business. Again, I'll re-iterate. Not all developers are working on shiny greenfield projects, and they do have to balance upgrades with the new work that the business is demanding. And not all developers are freelance who can just walk away from companies that run legacy code, and walk into new jobs with the latest shiny, latest tooling, and latest processes. And the attitude of some here on PHP Internals that we should just ignore those who can't develop in greenfield environments using the latest shiny, or that it should just be a simple upgrade step from last version to current release... that's the equivalent of having unit tests that only test the happy path. In my opinion, it's not the job of the internals developers to solve legacy system issues. They are developing a language, they are making sure deprecations are issued well in advance, sometimes through multiple versions and only then the feature is completely removed or made a full-on error.

No one, *literally no one*, in all of the Internals community is "forcing" you or anyone else to "rewrite" your entire code base. Asserting that is a lie. It is disinformation. And it makes it less likely that anything will change; I know multiple internals devs who are not in this thread, who have been doing the work of keeping PHP going and moving it forward (and I do not count myself among their number), who took one look at this thread and went "nope, not this crap again, not interested." >> Perhaps the risk analyses et al that Mark Baker talked about would be more >> likely to happen if core devs weren't insulted on a regular basis by people >> making hyperbolic lies and trashing their existing efforts. >> >> I've written about this before, just recently.

When more voices come on the list and raise reasonable concerns? Sure, welcome. When more voices come on the list and lie? No, that's not welcome. The OP at the start of this thread sounded earnest, even if this is a well-deceased horse by now. The initial responses to him were reasonable. The hyperbole that a few people are tossing around is not. Could internals do better on BC, to make upgrades easier? Yes! I have said so many times. I proposed several possible improvements in the blog post above. Mark Baker has focused on better risk analysis elsewhere in this thread, and that's fine. A more formal, standard way to measure the risk of a change would be a good thing. Let's discuss that. Do you have an actionable, concrete proposal for how to let PHP continue to get rid of 20 year old bad ideas that make development worse for everyone, while minimizing the hassle for the most developers? If so, please share that instead of spreading nonsense about "have to rewrite everything." As soon as you get into that hyperbole, you lose all credibility and no one cares if you are raising valid concerns. Let's discuss how *specific* changes could have been handled better, in a non-judgmental fashion, so that we can collectively do better on the next similar change.

This is pure and simple is a company issue. Now they have to pay for their decision by probably buying some 3rd party extended support. P.S. I wish all the luck to the teams going with TypeScript rewrite. Having dealt with NodeJS on a sizeable project - never again (the npm ecosystem has an atrocious problem with code quality and bugs that are not fixed for decades - you have to raw dog it on low-level nodejs drivers and modules to get code that works reliably).

Whatever message you're trying to get across has not reached me, at least. But I also know whatever message I'm trying to get across will not reach you. In fact, this is precisely the type of toxicity that habits Internals during controversial discussions. While you have decided that I'm a ungrateful enemy that wants to trash talk about volunteers work, I'm actually here spending my time advocating for things that I believe could improve on PHP out of pure selfish reasons: I don't want to leave PHP and I don't want to be forced to take a NodeJS job, but the little bubble I live in that's becoming the only way forward. On Twitter you see a lot of folks advocating for more voices and participation on Internals even if you don't have a vote. But when we come here to participate this is how we're received?

Telling them that the debt collectors and lawyers are here isn't going to help them when the people that pay them so they can eat and have a roof over their heads and care for their families is a slap in the face to them when they are torn between business demands and wanting to do technical upgrades. And the attitude of some here on PHP Internals that we should just ignore those who can't develop in greenfield environments using the latest shiny, or that it should just be a simple upgrade step from last version to current release... that's the equivalent of having unit tests that only test the happy path. -- Mark Baker -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: https://www.php.net/unsub.php

As far as I'm aware, browsers have no specific support for HTML 4. Arguably, they have no specific support for HTML 5, either. They (aim to) implement the "HTML Living Standard", which has a carefully designed parsing algorithm and three modes ("no-quirks", "quirks", and "limited-quirks"), which standardise and emulate certain behaviours of older browsers, not necessarily older specifications. Certainly, web technologies like HTML + DOM, JS / ECMAScript, and CSS, are good examples of carefully maintaining compatibility where possible, and including features specifically to keep old websites working. But that doesn't mean no feature is ever removed, and no default behaviour ever changes. Nor will there be an ever-growing list of switches to go back to what things looked like 10, 20, 30 years ago. That's because maintaining extra behaviour is difficult - adding the feature switch might be just a few lines of code, but it will *multiply* a section of tests; and it will need to be re-implemented to pass those tests every time the surrounding code is refactored, and accounted for every time a related feature is added. That might be worthwhile for one or two switches - HTML's "quirks" & "limited-quirks", JS's "use strict" - but it doesn't scale, so it's never going to replace the genuinely hard question of how to improve a language for new code, while limiting pain for existing code.

We're asking for proper analysis of the effects of these changes on end users, and proper consideration of the time that it will take for end-users to upgrade... and the answer to that is NOT "within a couple of hours". Call it unnecesary overhead if you will, but many tech teams have process flows for their work that don't simply entail "run rector on your codebase and deploy". Even just the admin overheads of raising a ticket for the change, creating a Merge Request, Peer Review, etc can take a few hours of time in many teams. And that's before making the assumption that all older code has a good test suite, and CI pipeline... if it has, then it's probably code that's being updated regularly anyway, by developers that do try to keep everything up-to-date. Nor are end-user developers the only people that are affected. End-user developers typically have the luxury of writing their code for a single version of PHP, so upgrading the version is a step from one version to the next. Library writers don't have that luxury: their codebase normally has to work with a range of PHP versions including the latest release; and any fixes that are made for the latest release still have to work with older PHP versions, which can take significantly more effort to maintain. -- Mark Baker -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: https://www.php.net/unsub.php

several PHP versions will be maintained for 10 years by third-party vendors. PHP5.6 will meet the 10 year mark by 28 august 2024, and freexian.com maintains PHP5.6 with multiple customers paying 6000€/year for 5.6 maintenance. Canonical intends to maintain PHP7.0 until April 2026 for their Ubuntu Pro 16.04. Canonical intends to maintain PHP7.2 until April 2028 for their Ubuntu Pro 18.04. Canonical intends to maintain PHP7.4 until April 2030 for their Ubuntu Pro 20.04. Canonical intends to maintain PHP8.1 until April 2032 for their Ubuntu Pro 22.04.

This is the failure of the business owner to plan accordingly and ignore all the warnings for years and decades. That is if any developer raised any concerns lately, which I also have seen quite a bit when "yes man" just shove code into the meatgrinder for a year or two and then just move to the next job: "It's not my problem, the next guy will deal with this". And that feeds the vicious cycle, and the owner is either oblivious or does not understand the implications because "well, it works, it generates money" at the moment right until that plane hits the ground and things blow up. I've handled a big legacy project, did major updates to it, seen how an effort of 1 month of my time to drag it into the modern day paid off over the next 6 months by picking up development speed by 3x with the same team of 5 people + me. In 1 year we started to literally take away clients from our competitors who could not keep up with us and we had a literal line of clients to onboard, we had to scale our sales team 3x and had a backlog of 6 months still. All stemmed from a single decision "I will tackle this, we need it to update to newer PHP". Business owners were really stoked that they actually listened to developers. You cannot expect to run code that was written 2 decades ago without major updates on modern language versions. It's not possible for almost any language that is being actively developed. Think laterally - instead of hand-fixing every null check out there, introduce a library that can handle data structures and handle the nulls for you en mass. Isolate the internals and just pass already sanitized values into it. Suddenly you cut off like 90% of the needed fixes that prevent you from running your code. It's still needs fixing, but at least you give it good data to start with, so it does not error out. -- Arvīds Godjuks +371 26 851 664 arvids.godj...@gmail.com Telegram: @psihius https://t.me/psihius

I've written PHP for 23 years, and I'm increasingly looking to other languages because they either come with a prewritten extension PHP doesn't have or because I can more easily hack one together to wrap a library (example: a new DB client) PHP has FFI but IMO it would benefit from further development.

Re: [PHP-DEV] Future stability of PHP?
I fully understand your point, having more tests is the best thing to do. Unfortunately many old code bases are not written to be tested easily. There is excessive inheritence, traits, reflection, globals, static calls, missing DI, magic functions, feature flags, database dependancies (e.g. 1 request reads 40 tables with 500 queries), library/framework dependancies (some unsupported, unmaintained, deprecated, etc.). So people spend a few months to get the coverage from 10 percent to 20 or 30 percent and the problems are still the same. My point is that every hour being spend on old code is one hour less that can be spend on writing newer code, being better tested, following newer standards, etc. So having language levels would make things a lot easier. There are many more things that should be deprecated and removed, but cannot be done now due to BC breaks and the risks for negative votings on the rfcs.

I keep reading this in multiple languages, pr even more frameworks. I understand agency work, managers pushing new features instead of a cleaning some legacy. however years of ignoring deprecation notices (very few were introduced right before 8.0).

How can they be finding those issues over a year later? Do they have pieces of completely untested code that has never been called in more than a year? If so, they have bigger problems than PHP deprecations. Otherwise, they should see the deprecation logs either on production or on CI. I highly doubt they're not collecting any logs from production, so they had more than a year to collect all the places where a deprecation is triggered and fix them. Speaking of those that ignore them, well, I'm not sure what the expectation is. Do they think the deprecation will simply go away on itself? Or do they expect the already small PHP team to infinitely support their code, sacrificing other developers' experience? Also, can you name an actively developed software product that introduced no breaking changes in the span of the expected 10 years? Besides, as mentioned before, it's likely that such projects are also using at least some other 3rd party PHP dependencies, and those usually have a shorter BC lifespan than PHP and require more efforts to keep them up-to-date. Again, is the expectation here to infinitely keep the backwards-compatibility? If so, why is it that almost every dependency follows Semver specifically to manage breaking changes, and there are practically no examples of actually avoiding breaking changes in the long term?

We aren't against PHP moving forward; we're not advocating that changes and improvements shouldn't be made. We are saying that they shouldn't be purely technical discussions about implementation here on Internals, but there should also be consideration for the impact on existing userland code. All too many of the changes made in 8.0, 8.1 and 8.2 had no impact assessment, no consideration of how much effort might be required for users to make the necessary changes in their code. Thankfully, I've started seeing some effort again to include a risk analysis or impact assessment in some of the more recent RFCs. And many of those RFCs work on the assumption that all existing PHP codebases are adequately covered by unit tests to identify the points where changes need to be made, and written well enough that any designated fix will always work. But in the real world, that is rarely the case, particularly with older codebases. Too often the RFCs seems to assume the happy path; with testing for edge cases in developers applications after release. > Nowadays there are even tools now like Rector that can help you automatically > upgrade your codebase - that is also a new value proposition. Tools like rector can help, particularly for developers that are specifically upgrading from one PHP version to another; and rector is certainly a game-changer there in the same way that Composer changed the way that we build applications and manage dependencies. Where rector is less useful is if we need to maintain the same codebase across multiple PHP versions, which is the case for many libraries, as well as some of the tools that we use for developing and testing. -- Mark Baker -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: https://www.php.net/unsub.php
Re: [PHP-DEV] Future stability of PHP?
I don't want to say that everything in old code bases makes sense, I just want to say that mixing null and empty string was quite common in the past, mostly coming from accessing undefined array keys. PHP has always been good to create new business value quickly. The problem now is that bringing all code into new standards does not bring new business value, so companies try to delay or refuse the upgrades as long as possible (also thanks to docker and others). Also many developers don't like upgrading code since it's either too boring or too challenging. The first thing done is mostly silencing deprecation messages, which makes the gap bigger when upgrading to the next major version. So having support for multiple php versions inside one binary would be a great thing, same as modern web browsers still support html 4 even though html 5 is out for so many years.

Most of the deprecations and changes do make sense, and while deprecating dynamic properties is going to be a pain, I think it's going to be worth it (like undefined variables), same with ${} string interpolation (better to be consistent); and I know it's been mentioned in this thread, but `utf8_decode` does get misused a lot (read the RFC as to why).

I should note that the other coercion/type tweaks that G.B.P (Girgias) is suggesting, and has partially implemented, do make sense: https://github.com/Girgias/unify-typing-modes-rfc And (fortunately) NULL coercion still works when concatenating NULL to a string, adding NULL to an integer, NULL being treated as false, etc. One team of developers I know are still finding these issues well over a year later (they also introduce new code that trips it as well); two other teams specifically ignore this deprecation (far too many instances to "fix"), and one team is still to decide what they are going to do (annoyingly they are still using 7.4). Even Rector gives up and uses `(string) $var` for every variable that's a non-nullable string, which can result in thousands of changes in a project (that's for the ~434 function arguments being checked; personally I'd have only gone with 335 of the ~997): https://github.com/rectorphp/rector-src/blob/main/rules/Php81/Rector/FuncCall/NullToStrictStringFuncCallArgRector.php Anyway, when PHP 9.0 makes this a type error, in the ~85% of code that isn't using strict types, that's going to cause lots of random and unexpected problems.

The PHP ecosystem even just in the last 10 years has changed completely, with composer, more mature frameworks, easily usable independent components and even static analyzers. For me that ecosystem is the big value proposition of PHP, in addition to a good standard library. Typescript has a completely different value proposition, and the language itself is usually not the deciding factor, as there is so much more to it. Only through the deprecations and the type system does PHP even offer some similar features as Typescript - like type checks and the possibility of a static analyzer. If all these changes would not have happened, people likely would argue even more that they had to switch to Typescript, because of the missing type safety in PHP. Nowadays there are even tools now like Rector that can help you automatically upgrade your codebase - that is also a new value proposition. My projects were affected by all the new warnings, deprecations etc. over the years, but I found countless bugs because of those (and many bad choices - is count($string) really what I wanted?).

Re: [PHP-DEV] Future stability of PHP?
Here are my 2 cents: The "dangerous" part of PHP upgrades is when you have more than one server and since you can't migrate a distributed system atomically, it often means that for a period of time, your code needs to support multiple versions (and you probably *always* have to do this for libraries). Personally, I've been bitten by small, undocumented, BC breaks that get marked 'wontfix' once reported, because fixing it after a release is considered a BC break. All I can do is facepalm while I update the code to handle different versions of PHP. I freakin love PHP, so I'm not going anywhere, but it would be amazing if core devs contributed to Rector (or something like it) that allowed you to run a simple tool to upgrade your code from "8.2 compatible" code to "8.2 + 8.3 compatible code" and then to "8.3-only compatible" code. The community does its best, but the core devs working on it know about the undocumented bits and probably the most efficient implementation. For all I know, you all are already doing this, and if so, you should tell the world.

On the other hand, throwing the existing community out and chasing after a new community puts PHP at a very delicate spot. There's a large world out there that thinks PHP is still PHP 4. Of the large group of PHP adopters that stayed with the language for the last decade, a large set seem to have their interests neglected and are being forced into greenfield/rewrite. If you've bet money on PHP 15 years ago and you're now being forced by the language to stay behind or rewrite, what are the odds that PHP will keep being the betting choice?

I love PHP. I have been working with it for 13 years now. I can also make things work with PHP 8+ and I get what it brings. But the cost is catastrophic. If you have a legacy codebase hanging over your head you probably know how hard it is to upgrade it. If you have greenfield project with SA and 100% coverage, it's a peach.

Re: [PHP-DEV] Future stability of PHP?
It depends on your environment and usecase. For me Node is actually a curious case. Node itself and its APIs are very stable and the stability of each API is clearly marked in the docs. But the NPM based ecosystem is almost the exact opposite. Using it for anything else than quick experiments or throw-away prototypes is a maintenance nightmare for people like me. Maybe you can amortize that in larger companies with an operations department but from what I heard and observed over the years admins and programmers don't tend to talk much with each other and most programmers have no idea what it takes to keep their code running. And I can deeply emphasize with every admin who has to keep a node project with hundreds of dependencies running for more than a few months. Lets not even talk about security. Nodes core APIs are pretty network centric (that's where it came from) and it was a good fit for a HTTP based Matroska video streaming server project (among other things). But as it turns out JavaScript is a pretty bad language if you need bit manipulation with 64 bits. I'm still curious why they made BigInt signed one's-complement… Writing that stuff in C was a lot simpler. As for websites with node but without NPM... I did that a few times but for the last two years I tend to use Python aiohttp instead. They have well maintained Debian packages and builtin websocket support. And very complex client-server interactions are often the threshold where I switch from webservers like Apache or Nginx to an application server. As for using PHP for new code bases: I think a lot of programmers underestimate the flexibility and simplicity of file based webservers like Apache with PHP. If you keep it simple they allow projects to grow organically. Need a new backend for something? Just put a few lines of code into a new PHP file. No update to a centralized application server or routes required. Want to have a search-engine friendly dynamic website? Just write a basic HTML page with a few lines of PHP in it to insert the actual data (the alternate control structure syntax basically gives you a builtin template system). Want to generate static pages instead? Use output redirection. Want to add simple user authentication? Add a password protection in the webserver. Or tell it to get the user data from LDAP if you're in a company. It plays well with source control, there are a lot of dirt cheap webhosters for small customers, the list goes on and on. All of that makes PHP a pretty good tool that can solve a lot of problems in very simple ways. A lot of that are just small projects, small customers or the inglorious everyday work that nobody likes but someone has to do. So it doesn't get talked about much. Big companies and teams on the other hand spend a lot of time talking about what they do and then there are also consultants that preach whatever sells today. Most tend to talk about what everyone else is doing and this doesn't necessarily has anything to do with a simple solution for your specific problem at hand. Of course all of that can flip on a dime depending on your environment: Part of a team where everyone has decades of Java experience? You're not using PHP, or node for that matter. Doing a project with a lot of rookies that only know stuff like express and react? Guess what you'll be using. Part of a team where everyone has their dedicated non-overlapping area of responsibility and authority (content, design, programming, etc.)? Now there is potential to use the right tool for the job.

I wasn't aware of that.

Yes, this seems to be the prevalent mindset people like to group themselves into. I don't have any good answers about that but a few languages seemed to have handled that rather well. Fortran for one changed a lot since its inception while still being very stable. And before the first one says that it's dead, a dinosaur or whatever: I thought so as well before I worked at a super computing center for a while (around 2010). There pretty much everything was written in Fortran and still is as far as I can tell. The language gets an update every 10 years or so and it's still a pretty good tool for physicists and engineers to write high-performance simulations. With Fortran 95 you can almost write Ruby-like code if you care about readability. Not that physicist do that since they name everything alpha, theta, phidash, etc. which doesn't help. Anyway, there might be something interesting to learn from languages that navigated the same problems before. Disclaimer: I'm not that old but I'm curious how programming as a discipline is done and changes in different fields and industries. So I dabble in a lot of different things.

There's no such guarantee at the moment. Anything that is agreed upon by the 2/3 majority of voters is subject to change. > Some of my projects run for 5 to 10 years, in one case even 20 years. There are companies that offer extended lifecycle support for PHP versions that have officially reached EOL (examples being Zend or TuxCare). I'm not sure if those will get you to that 10 year mark. Note however that deprecation notices alone should not keep you from upgrading to a newer version, as they don't have any runtime effect with a correct production configuration and thus aren't considered breaking. We generally postpone larger breaking changes to major versions. In general, I do agree that we could minimize breaking changes more, and limit them to the things that actually provide a tangible benefit. Sadly, there's a conflict of interest here. There are people who want to keep running their existing websites without having to make any changes, and there are people who are using PHP daily and would like to see the language evolve. We would like to satisfy both of these groups but that is difficult when they are often directly opposed. I do think that if we only manage to satisfy the former, PHP will gradually become less and less significant. That would be sad.

Re: [PHP-DEV] Future stability of PHP?
I agree with the OP's sentiment here. If I was starting a codebase from scratch today, I'd probably go with Node. I find that writing modern JavaScript is way easier than writing PHP these days, and the breaking changes in newer PHP versions make writing code harder rather than easier. PHP is the foundation for many legacy codebases, and breaking old projects isn't really a great selling point of new PHP versions. Hopefully this scenario will affect enough people that 7.4 will continue to be maintained by some group of people into the foreseeable future.

Re: [PHP-DEV] Future stability of PHP?
Hi Stephan, Generally, PHP tries to keep as much backwards compatibility as possible. Breaking changes are limited to minimum and done in the least obstructive way possible. When a deprecation is introduced, you have at least 3 years to update your code. But PHP also tries to move forward and the language improves each year. We certainly got many more features than breaking changes. Just think of match expression, enums, attributes, constructor property promotion, new Random API, readonly properties/classes, first-class callable, consistent errors and many more. The biggest improvement in PHP 7 and 8 was a comprehensive type system. It's something that you don't have to use, therefore doesn't affect existing code much, but makes development so much more enjoyable and less bug-prone. I know I have discovered many bugs because of migration to PHP 8 and introduction of proper types. And this is the direction PHP is going in. The language is still dynamic and allows for taking the easy route, but new features focus on reducing bugs by making the code's behaviour less surprising. If you try to adhere to clean code principles, upgrades should not be a huge problem. Use static analysis and good tests. Learn and follow clean code practices, e.g. SOLID. Use abstraction in your code; it's better to change code only in one place than change it across hundreds of files. Some tools help you during migrations, such as Rector and phpcbf, but to use them proficiently, your code needs to be free from surprises. Dynamic properties are a very good example of surprising behaviour. By looking at the definition of the class, you don't know what properties it has. If any of the methods use undefined properties, both you and static analysers will be surprised by this. There are certain things you should avoid in your code like fire. Not because they might be removed from the language, but because they make your code unclean and cause bugs. Here is my list: - Arrays. Yes, they are a major feature of the language but also a major pain in the... Use proper data structures, which may use arrays internally, but don't use bare arrays in your code. Value objects and DTOs are invaluable. - Isset and empty. They are sometimes necessary and sometimes they are the easiest choice, but they hide so many bugs. Every time you use any of them, it should raise an immediate red flag. - References. I don't understand why the language still has this feature. Hack got rid of it and that was a very smart decision. You don't need references. Use them almost never. - Globals and superglobals. This should not need explaining. Pretty much in every language, these are pure evil. They make changes to the code an experience similar to disarming a bomb. It's tempting to use $_GET, $_POST, $_REQUEST anywhere in your code, but if you want to avoid bugs and surprises, you'd better stay away from it. There should probably be at most one place in every project where these are used. - extract() and compact(), and variable variables. These should only be used in a very tightly controlled scope, and even then, their usage can be contested. Ideally, variable variables should not exist in the language; we have arrays after all. - Sanitizing filters. Sanitization is too ambiguous term to be useful. What you should be using is validation and formatting. Validate your inputs to make sure they are the type/value you expect. Format the output so that it can't break the context it is in. - Loose comparison. I have liked that about PHP in the past, but in recent years I became a strong supporter of strict comparison. Why? Because "0" == false. Forbid using loose comparison in your coding standard and forget that it exists. Don't let the language make a fool out of you. You are the developer and you know what type you expect. Following these guidelines will not only help you avoid bugs in your code but also will make the upgrade process much less cumbersome. This and adhering to the strictest level of the static analysis tool of your choice is the recipe for success. Try to stay up to date with the changes. Every year when PHP releases a new version, go over the changelog and make an effort to learn and use new features. Even if your production is 3 years behind, you can try these out in your development environment. PHP will move forward and add new features, but sometimes it must also break some things to move forward. Kind Regards, Kamil Tekiela
