If you wish to allow newlines, instead of " \t" you should use the whitespace selector "\s" <?php $comment = 'Testing 12345. This is a test of the emergency broadcast system. WAKE UP!!!!!!'; if(!preg_match('|^[a-zA-Z0-9!?@#$%^&*();:_.\\\\\s/-]+$|', $comment)) { echo 'oops'; } else { echo 'ok'; } ?> Try that code sample, and you'll see that it says "ok" What exactly are you trying to accomplish with this preg_match()? What exactly are you trying to filter out? I understand you want to eliminate "invalid characters" but why are they invalid? I ask because there may be a simpler way to solve the problem, if you can explain what the problem is. Thanks, Greg
