I don't see anything initially wrong with this statement, but you might try a variation and see what you get.
First: condense this: $DB_sub_ref = substr($DB_temp_ref , 0, 1); $DB_sub_ref .= substr($DB_temp_ref , 1, 1); to this: $DB_sub_ref = substr($DB_temp_ref , 0, 2); Your code will run slightly faster... Second change the third line there to: $DB_sub_ref .= substr($DB_temp_ref , -1); That should do the same thing, grab the last character in that string. Try that and see what you get.
