DirectoryIterator extension to get the file-extension: class MyDirectoryIterator extends DirectoryIterator { public function GetExtension() { $Filename = $this->GetFilename(); $FileExtension = strrpos($Filename, ".", 1) + 1; if ($FileExtension != false) return strtolower(substr($Filename, $FileExtension, strlen($Filename) - $FileExtension)); else return ""; } }
