What that tells me is that the 7, 8, 9, 13, 16, and 18th iterations of the loop actually matched something with preg_match. The other loops did not. You may want to check the result of preg_match before you try to save the value. Then you won't end up with all of those empty arrays inside of $matches. ---John W. Holmes...
