 in PHP multi level break is performed with the keyword break followed by a number 
 indicating how many level to break from so break 4 would exit out of a loop depth 
 of 4.

 Example

 PHP:

 for($i = 0; $i < 10; $i++){
     for($j = 0; $j < 5; $j++){
         if($j == 3)
             break 2;
     }
 }

 Rust

 for i in 0..10{
     for j in 0..5{
         if j == 5
             break;
     }
     if j == 5
         break;
 }
