Better Get File Extension
<![CDATA[
<?php
// Function that get file extension
// Returns an empty string if file has no
// extension
// I try to use regular expression as much
// as possible when working with strings
// because this way you never have to deal
// with string indexes.
function ReallyGetFileExtension( &$filename )
{
return ereg( ".([^\.]+)$", $filename, $r ) ? $r[1] : "";
}
