I’ve been working on a theme for PHPStorm which is a port of the Monokai colour scheme from Sublime Text 2. It should cover PHP, HTML, CSS, Javascript, XML and ini formats.

You can download the theme here.

Monokai ported to PHPStorm

To install, save the .jar file locally then select File > Import Settings in PHPStorm. This should only add a colour scheme and not affect any other settings in the IDE.

There is an existing port Monokai by Haza The colours there looked a bit washed out on my monitor, but its certainly worth a look.
