basename — Returns trailing name component of path
Given a string containing the path to a file or directory, this function will return the trailing name component.
Note:
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.
If path contains characters which are invalid for the
current locale, the behavior of basename() is undefined.
pathA 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 the base name of the given path.
Example #1 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)
