The pathinfo Function
The pathinfo function returns an array with information about a file path. We pass a string with the path as the first parameter, and a flag as the second parameter, indicating which specific path component to return.
Syntax
pathinfo(string $path, int $flags = PATHINFO_ALL);
Flags
| Flag | Description | Returned Element |
|---|---|---|
PATHINFO_DIRNAME |
Returns only the file directory | dirname |
PATHINFO_BASENAME |
Returns only the filename (with extension) | basename |
PATHINFO_EXTENSION |
Returns only the file extension | extension |
PATHINFO_FILENAME |
Returns only the filename (without extension) | filename |

<?php
$res = pathinfo('/var/www/index.php');
print_r($res);
?>
Code execution result:
[
'dirname' => '/var/www',
