basename

(PHP 4, PHP 5, PHP 7)

Returns trailing name component of path

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.

Returns:

Returns the base name of the given path.

Notes:

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

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.

Examples:

basename() example

<?php
echo "1) ".basename("/etc/sudoers.d", ".d").PHP_EOL;
echo "2) ".basename("/etc/sudoers.d").PHP_EOL;
echo "3) ".basename("/etc/passwd").PHP_EOL;
echo "4) ".basename("/etc/").PHP_EOL;
echo "5) ".basename(".").PHP_EOL;
echo "6) ".basename("/");
?>

The above example will output:

1) sudoers
2) sudoers.d
3) passwd
4) etc
5) .
6)
