PHP Manual: Returns trailing name component of path

Description

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

Given a string containing the path to a file or directory, this function will return the trailing name component.

Parameters

path

A path.

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

suffix

If the name component ends in suffix this will also be cut off.

Return Values

Returns the base name of the given path.

Changelog

Version	Description
4.1.0	The `suffix` parameter was added

Examples

Example #1 basename example


<?php
echo "1) ".basename("/etc/sudoers.d", ".d").PHP_EOL;
echo "2) ".basename("/etc/passwd").PHP_EOL;
echo "3) ".basename("/etc/").PHP_EOL;
echo "4) ".basename(".").PHP_EOL;
echo "5) ".basename("/");
?>

The above example will output:

1) sudoers
2) passwd
3) etc
4) .
5)

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.
