Breaking out of two foreach loops?

[ninja9578]

What is the proper way to break out of two or more foreach loops? break obviously won't work. I could add a flag that is set before the first break and checked before each loop, but that seems really inelegant.

I am currently using the old calling card of the devil: goto

foreach($something as $foo){
   foreach($foo as $bar){
      if ($bar == 'whatever') goto sixsixsix;
   }
}
sixsixsix:

What is the proper way to do this? I'm used to C++ where we don't have foreach and use custom conditions.

You're in luck - in PHP, 'break' can take a numeric argument telling it how many nested structures to break out of. These can be any of for, foreach, while, or switch.

So in your case,

foreach($something as $foo){
   foreach($foo as $bar){
      if ($bar == 'whatever') break 2; <-- breaks out of both loops
   }
}

Useful, isn't it?
