Description:

it is an extension of the C mode, it inherits all of that mode's
navigation functionality. It's syntax highlighting colors code
according to PHP's grammar, however, and indents it according to the
PEAR coding guidelines. The mode also includes a couple of handy
IDE features such as documentation search and a source and class
