foreach within foreach...

[youradds]

I'm trying to escape out of a main foreach statement. In Perl you can use something like;

NAME: foreach (@array) {

  if ($var eq "testing") { next NAME; }

}

As I'm sure you can guess, this basically skips the array, and moves onto the next array. Basically, I'm trying to do a similar thing in PHP;

  $count = 0;
  [red]GOTHROUGH:[/red] foreach ($titles as $_titles) {
  
             if ($_titles == "$title") {

               if ($cats[$count] == "$category") { 
                 $found = 1;
                 [red]continue GOTHROUGH;[/red]
               }
 
             } // end the 'if'

            // if we don't have a match, then lets put it back in...
             if (!$found) { 
               array_push($back_cats,     "$cats[$count]"); 
               array_push($back_titles,   "$_titles"); 
               array_push($back_est1,     "$ourestimate[$count]"); 
               array_push($back_est2,     "$theirestimate[$count]"); 
               array_push($back_est3,     "$actualcost[$count]"); 
               array_push($back_assigned, "$assignedto[$count]"); 
             }

            // increment the counter...
             $count++;

  } // end main 'foreach'

The problem is, that I'm not sure of the syntax. Does anyone know? The current format gives me a parse error.

Any help is much appreciated

try break;

Doesn't break only take you out of one of the foreach's though?

To jump to the top of a looping structure you should use:

foreach($array as $value){
   if ($value == 'breakcondition') continue;
    # code
}

Break end the loop and jumps to the line after the loop ending indicator.

Thanks, that worked a treat

For future reference, is there such a thing as 'naming' for 'foreach', that will enable you to break out of a specific foreach? I remember seeing something like;

break 1;
break 2;
break 3;

i.e break 1 would break out of the first foreach, break 2 would break out of the current foreach, and another one, break 3 would break out of the current foreach, the one above that, and the one above that. Is this a valid format? I can't seem to find the page again

Cheers

Yes, there is.
Break takes an optional arguments that tells how many structures it should exit from.
