php foreach continue

Question

I am trying to skip to the next iteration of the loop if certain conditions are not met. The problem is that the loop is continuing regardless.

Where have I gone wrong?

Updated Code sample in response to first comment.

    foreach ($this->routes as $route => $path) {
        $continue = 0;

        ...

        // Continue if route and segment count do not match.
        if (count($route_segments) != $count) {
            $continue = 12;
            continue;
        }

        // Continue if no segment match is found.
        for($i=0; $i < $count; $i++) {
            if ($route_segments[$i] != $segments[$i] && ! preg_match('/^\x24[0-9]+$/', $route_segments[$i])) {
                $continue = 34;
                continue;
            }
        }

        echo $continue; die(); // Prints out 34

You are overwriting $continue. It is entirely possible to enter that it gets set to 1, then 2 in your loop iterations. — Jason McCreary

Set $continue = 0; right after the foreach... I'll bet you won't get 1 anymore. A for 2, you'd need to tell it to continue up 2 levels, so continue 2;, otherwise it'll just go to the next iteration of the for loop... — ircmaxell

If you are trying to have your second continue apply to the foreach loop, you will have to change it from

continue;

to

continue 2;

This will instruct PHP to apply the continue statement to the second nested loop, which is the foreach loop. Otherwise, it will only apply to the for loop.

The second continue is in another loop. This one will only "restart" the inner loop. If you want to restart the outer loop, you need to give continue a hint how much loops it should go up

continue 2;

You are calling continue in a for loop, so continue will be done for the for loop, not the foreach one. Use:

continue 2;

The continue within the for loop will skip within the for loop, not the foreach loop.
