File extension not being retrieved

[owinocliff]

$file->getNameWithExtension() doesn't return the name with the extension, just appends the "dot" but without the extension

If you want to get the extension in PHP than you can use this

function get_file_extension($file_name) {
	return substr(strrchr($file_name,'.'),1);
}
