hey guys please new php mysql, trying generate code del-12345. if person chooses state delaware in form, generates , stores del-23413 in db on submit. del (first 3 letters of state); - (hyphen) , 12345 (5 random numbers)...

please help

i point in right direction code below.

$area = "utah"; $code = strtoupper(substr($area, 0, 3)) . "-" . (mt_rand(1000,9999)); echo ( $code );
