string basename ( string $path [, string $suffix ] )

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

Changelog #

Version Description
4.1.0 The suffix parameter was added

Notes #

Note:

basename() operates naively on the input string, and is not aware of the actual filesystem, or path components such as "..".

Note:

basename() is locale aware, so for it to see the correct basename with multibyte character paths, the matching locale must be set using the setlocale() function.
