Breaking the nested loop [duplicate]

Question

Unlike other languages such as C/C++, in PHP you can use the optional param of break like this:

break 2;

In this case if you have two loops such that:

while(...) {
   while(...) {
      // do
      // something

      break 2; // skip both
   }
}

break 2 will skip both while loops.

This makes jumping over nested loops more readable than for example using goto of other languages
