Recently PHP 5.4.0 Alpha 1 was released and the PHP development team is asking every PHP user to test it. In this blog I have some articles about upcoming features in that version. Now is a good time to test 5.4 in combination with your applications spot mistakes (complain now if we break compatibility, now we could fix it ...) and a good time to prepare your knowledge.

These are the articles I published here:

• Mind the encoding
• Improved interactive shell
• Jason, let me help you
• Array dereferencing
• No more extension for SQLite 2
• Upload progress

I also have articles on a feature which does not make that release:

• Scalar type hints in PHP trunk
• More on scalar type hints in PHP

I plan to continue that series, focusing on things which might be overseen easily. It's a bit time till 5.4 will be released as GA but the more you test it and give feedback the better it will be!

I was writing about new features in the upcoming PHP version (5.4, 6.0?) before. Today's topic reads like this in the NEWS file:

- Added array dereferencing support. (Felipe)

Now you might wonder what this typical short entry means. when doing OO-style PHP you might make use of a sntax feature which one might call "object dereferencing" which looks like this:

<?php
class Foo {
    public function bar() { }
}

function func() {
    return new Foo();
}

func()->bar();
?>

So one can chain method calls or property access. Now for a long time people requested the same thing for array offset access. This was often rejected due to uncertainties about memory issues, as we don't like memory leaks. But after proper evaluation Felipe committed the patch which allows you to do things like

<?php
function foo() {
    return array(1, 2, 3);
}
echo foo()[2]; // prints 3
?>

Of course this also works with closures:

<?php
$func = function() { return array('a', 'b', 'c'); };
echo $func()[0]; // prints a
?>

And even though the following example is stupid I might accept this feature as one of the few places where it is ok to use references in PHP:

<?php
$data = array('me', 'myself', 'you');
function &get_data() {
    return $GLOBALS['data'];
}
get_data()[2] = 'I'; // $data will now contain 'me', 'myself' and 'I'
?>

Wonderful, isn't it? If you want to test it please take a look at the recent snapshots for PHP trunk and send us your feedback! Please mind that all features in PHP trunk may or may not appear in the next major PHP release.

It was a long run and I'm sure it felt like an eternity for many - for me it certainly did. PHP 5.3 was branched of over two years ago and finally is ready to be called 5.3.0.

The php.net website and many other blogs discuss the features - from often loved closures, to well discussed namespaces to the sometimes hated goto - so I think I don't have to this here but instead can focus on that what really matters:

• Thanks to all the developers - Without them no new features would be there.
• Thanks to the documentation team - Without them one would have to decipher the NEWS file and guess what exactly is meant.
• Thanks to all participants during the Testfest! - During the Testfest we received many good tests for our regression test suite. Many of these tests represent what people do, not what developers think they should do which is important to reduce the risk of regressions. I hope people don't stop sending tests!
• Thanks to all the testers who reported bugs, and to the ones who reported that their applications worked without issues! - Regression tests are important but many possible issues can only be found in real life scenarios with real applications.
• Thanks to the whole community to make pressure on the developers to finally get it out as everybody is waiting for the new features.
• And last, but certainly not least: Thanks to Lukas! - Handling developers who are passionate for their work can be tough. Lukas made sure that the developers focus on what really matters and really helped me with all the work needed

So with that: In case you didn't do already: Browse over to php.net and grab your copy, it's for free!

If you want to celebrate the release and are close to Munich: We're planing a PHP Release Party on July 17th, details on that will follow.

It's done 5.3 finally, after quite some discussions, reached beta state. So if you're not already on it it's now the perfect time to test it. Problems found now can be fixed before we mark it stable. Issues not find might need workarounds in your software which will cost you more time in the end. Or the way I often put it: Test now and complain or don't test and live with the consequences - we do our best but we certainly can't cover every edge cases especially in a version like 5.3 where we did quite some internal cleanup and added tons of new features.

The NEWS entry file is, compared to some previous alpha versions, quite short this time but still worth reading if you tested a previous alpha release.

Source tarballs can be found in my download directory, Windows builds in the Windows QA area.

Happy testing!

Mal ein deutsches Posting zu PHP: Im Rahmen der "Weg mit magic_quotes"-Diskussion muss ich einfach Karl Valentin zitieren:

Mögen hätt ich schon wollen, aber dürfen hab ich mich nicht getraut.

As most of you might have seen we recently announced the first alpha of PHP 5.3.0. The major changes are listed in the announcement. Source tarballs can be found on PHP's downloads site, as it's the first release I packaged I'm especially interested in feedback, whether it works or not . But we didn't only have changes on the source builds: A new team took over the creation of Windows builds. As they also did a major update to the Windows build architecture (supporting newer compiler versions on Windows and added experimental support for 64bit platforms) the build process got a bit delayed but builds should be available soon.

Remember: It's a release we packaged to get feedback from our users. So please test it. If you find issues please report them - the sooner we know about issues the sooner they can be addressed. Although our test coverage increased we can't cover all cases in our tests so please test it now and don't wait for the stable release, once the stable release is out your edge case might trigger a bug on a productive system, bugs reported now can be fixed before we release a final version.

If you want to give back to the PHP project - hey you probably make a living out of software you get for free - and can't fix bugs or assist in a similar way you probably could help our documentation team with improving the documentation, there are a few features without proper documentation, yet.

The PHP TestFest was mentioned on Planet PHP multiple times before, so let's make it one more: Pierre and me are currently working on organizing a TestFest event at Munich. So we are looking for feedback from folks somewhere in the Munich area (or even all of southern Germany) so we know how many people to expect and then set a date. The requirement is mainly having experience with PHP. Being able to read C code might help here and there but is no requirement - it's way more important to be interested in PHP. So if you're interested in meeting core devs and participating in the TestFest and possibly win a few nice prizes please take a look at the TestFest page to get more information and leave a note to me at johannes on php.net so I can do my planning.
