Two and a half years after the release of PHP 5.2.0 and following a slight delay, the PHP development team have announced the release version 5.3.0 of PHP. Version 5.3.0 of the web programming language includes several fundamental new extensions, as well as a number of other new features and is the one of the biggest revisions in PHP’s history. Many of the functions originally planned for PHP 6 have ended up in the 5.3 development pipeline.

The main things to note are:

• PHP 5.3.0 now a namespaces (a language feature that allows the same name for a constant, class or function to be used in different namespaces without triggering a conflict.)
• Object-oriented programming type dynamic/late static bindings.
• PHP has a new garbage collector
• Modifications to the PHP interpreter affecting both execution speed and memory usage.
• mysqlnd, an implementation of the MySQL client/server protocol developed and optimised for PHP,

More details about the 5.3.0 release can be found in the release announcement and the PHP 5 ChangeLog. PHP 5.3.0 is available to download. A migration guide is also provided for users upgrading from PHP 5.2
