note 88654 modified in function.pathinfo by danbrown

Here is a simple function that gets the extension of a file. Simply using PATHINFO_EXTENSION will yield incorrect results if the path contains a query string with dots in the parameter names (for eg. &x.1=2&y.1=5), so this function eliminates the query string first and subsequently runs PATHINFO_EXTENSION on the clean path/url. <?php function extension($path) { $qpos = strpos($path, "?"); if ($qpos!==false) $path = substr($path, 0, $qpos); $extension = pathinfo($path, PATHINFO_EXTENSION); return $extension; } ?> --was-- Here is a simple function that gets the extension of a file.
