Ok. So Im running through two arrays making sure the values do not match
each other and if one value in array b does match a value in array a,
what I want to happen is: 

foreach($arrayb as $key => $value){
   if($value == $array[$getrandnumb]){
      $getrandnumb = getrandnumb($result);
      // I want to recall this function to get another number
      // but it needs to jump OUT of this foreach loop so it can then
      // be run again.
        $taken = 1;
   } else {
      $taken = 0;
   }

}

How can I do this?
