Test a Form Entry Against a CSV File.

The simple way.

	if(empty($input))

	//if the input isn't 6 alphanumeric characters, go no further
	if(!preg_match('/[A-Za-z0-9]{6}/i',$input))
		return 'The code provided is not valid.';
	//finally, test against the list
	$filepath = dirname(__FILE__).'/data/datafile.csv';
	if (($list = fopen($filepath, "r")) !== FALSE) {
		while (($data = fgetcsv($list, 1000, ',')) !== FALSE) {
			if($input == $data[0]){

		}
		fclose($list);
	}
