Break statement inside two while loops

Question

Let\'s say I have this:

while(a){

  while(b){

   if(b == 10)
     break;
 }
}

Question: Will the break statement take m

Answer 1

As a curious note, in PHP the break statement accept a numeric parameter which tells how many outer loops you want to break, like this:

$i = 0;
while (++$i) {
   switch ($i) {
      case 5:
         echo "At 5
\n";
         break 1;  /* Exit only the switch. */
      case 10:
         echo "At 10; quitting
\n";
         break 2;  /* Exit the switch and the while. */
      default:
         break;
  }
}
