Note Submitter: 2072@2072productions.com ---- Here is a much better, reliable function to check the extension of an uploaded file: <?php function checkext($filename, $search) { if (stristr(substr($filename, -4), $search) !== false) return true; else return false; } ?> This functions look at the 4 last letters of the filename ignoring case, looking only the 3 last letters is not reliable at all: a file can have no extension... example, we check if the file is a ".rar" file: <?php $thisisararfile = checkext($_FILES["userfile"]["name"],".rar"); if ($thisisararfile) echo "OK, this is a .rar file!"; ?> Note that the "." must be included in the $search parameter.
