After many months of active development, PHP 5.4.0 is now generally available :
The PHP development team is proud to announce the immediate release of PHP 5.4.0. This release is a major improvement in the 5.x series, which includes a large number of new features and bug fixes.
Some of the key new features include: traits, a shortened array syntax, a built-in webserver for testing purposes and more. PHP 5.4.0 significantly improves performance, memory footprint and fixes over 100 bugs.
For users upgrading from PHP 5.3 there is a migration guide available here, detailing the changes between those releases and PHP 5.4.0.
Further details about the PHP 5.4.0 release can be found in the release announcement, and the full list of changes are available in the ChangeLog.
On the Dotdeb side (thanks to Debian developers’ preliminary work), I’m proud to announce that preview packages of PHP 5.4.0 are now available for Debian 6.0 “Squeeze” on amd64 and i386 architectures. You are invited to test them on development servers, but please don’t install them on production servers yet : the Suhosin patch has not been applied, some extensions are not fully compatible and the following ones are missing…
Don’t worry, production-ready PHP 5.4 packages will be available in some few weeks, after the Suhosin patch and the missing extensions are published.
To avoid your servers to be accidentally upgraded from PHP 5.3 to PHP 5.4 without compatibility validation, the PHP 5.4 packages are available on a separate path. To install them, you’ll have to add this line to your /etc/apt/sources.list first (you can also use any Dotdeb mirror once they’re synchronized) :
deb http://packages.dotdeb.org/ squeeze-php54 all
The main changes in the packages :
- if you need MySQL-related functions, you can now choose between the (libmysqlclient-linked) php5-mysql package and the (MySQL native – and better – driver-linked) php5-mysqlnd one
- PHP extensions config files are now migrated to /etc/php5/mods-available/. Files in /etc/php5/conf.d/ are now just symlinks to them. Therefore, you can activate PHP extensions by using php5enmod/php5dismod.
I hope you’ll enjoy this new packages. Any feedback or donation is highly appreciated.
