PHP 5.4.0 Released!

What’s New In PHP 5.4.0?

The PHP Development Team would like to announce the immediate availability of PHP 5.4.0. This release is a major leap forward in the 5.x series, and includes a large number of new features and bug fixes. Release Announcement:

Short Array Syntax

One of my favorite updates in 5.4 is the short array syntax. Being able to define an array with [] instead of array() is more of a cosmetic and ease of use update than a performance increase.

// as of PHP 5.4 
$array = ["foo" => "bar", "bar" => "foo"];
