Ok, well there are a number of ways in which it can be done. Possibly the easiest (although not the best) is to use strrpos (http://php.net/manual/en/function.strrpos.php) to find the last '.' in the string, so you have something like

Code:

$ext_start = strrpos($filename,'.') - 1;
$filename = substr($filename,$start,$ext_start);

That will give you the filename minus the extension. Then do

Code:

$file_ext = substr($filename,$ext_start,strlen($filename));

That will give you the extension. So store both in the database in separate fields and you can then do what you want to do.
