The OP needs to know if it's the first 4 or not and so position 0 would be the start. Very nice. Now, if his data is always of the format XXXX-XX-XX as it was illustrated, then this will also work if (strpos($mydata->restored, '0000-') !== false) { do stuff; } (note the hyphen) and you should check the === false -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
