The bestest way to get the extension is of course
<?php
$ext= strtolower(substr($filename, strrpos($filename, ".")+1);
?>
This performs well on PHP 4 and 5, with short and long $filenames.
On PHP 4, the fastest one is
<?php
$ext= strtolower(pathinfo($filename, PATHINFO_EXTENSION));
?>
but with PHP 5 and a long $filename it takes almost twice the time of substr(strrpos()).
