Hi,
Your sample text contains newlines. 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
