Won't work either. The problem lies in using the === comparison
operator. preg_match() returns 0 if no match is found, and FALSE if an
error occurred. So using === will always echo 'No spaces' whether
there were spaces or not, provided that no error has occurred.
if (!preg_match('/\s+/i', $string))
{
echo 'No spaces';
}
should suffice.
