Usage: string basename ( string path [, string suffix] )

Purpose: Returns filename component of path
Availability: PHP 3, PHP 4  

Given a string containing a path to a file, this function will return the base name of the file. If the filename ends in suffix this will also be cut off.

On Windows, both slash (/) and backslash (\) are used as path separator character. In other environments, it is the forward slash (/).
