'Twas brillig, and Miller, Terion at 31/07/09 17:11 did gyre and gimble:

If (ctype_digit($row['critical'])){        echo(" Critical violations found: ". $row['critical'] .". ");

Remember that empty() does clever stuff for you. empty('') == true empty(0) == true empty('0') == true empty(1) == false empty(2) == false empty('foo') == false I suspect you were just being bitten by a misconception of what empty() was supposed to do when you passed certain values to it. isset() and empty() are subtly different.
