if you press F5 -> you can see that preg_match shows different values
I recorded it on video

Test script:
$text = '*/10 * * * *';
if(preg_match('/[^0-9\*\/]/', $text )) echo 'preg_match GOOD! <br/>'; else echo "preg_match BAD!<br/>";

This feature appears to be controversial, and as such would
require the RFC process[1].  Anybody is welcome to start it! For
the time being, I'm suspending this ticket.
