basename - Returns trailing name component of path

SYNOPSIS
string basename (string $path, [string $suffix]) DESCRIPTION
Given a string containing the path to a file or directory, this function will return the trailing name component. PARAMETERS
o $path - A path. On Windows, both slash ( /) and backslash ( ) are used as directory separator character. In other environments, it is the forward slash ( /). o $suffix - If the name component ends in $suffix this will also be cut off. RETURN VALUES
Returns the base name of the given $path. EXAMPLES
Example #1 basename(3) 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) NOTES
Note basename(3) operates naively on the input string, and is not aware of the actual filesystem, or path components such as " ..". Note basename(3) is locale aware, so for it to see the correct basename with multibyte character paths, the matching locale must be set using the setlocale(3) function. SEE ALSO
