You can suppress warnings by setting the proper error_reporting() level
(see manual), or by prepending your function call with @.

Then check for the returned value by the regex function and use
trigger_error('Your message',E_USER_WARNING). (Again, see manual for
details)

if (! @preg_match($pattern,$string,$match_arr) {
trigger_error ('Blahblah', E_USER_WARNING);
}
