Php – Restart for each loop if Boolean

How do I restart a foreach loop when I reach the last index and some other condition?

The loop needs to run again, instead, it just stops.

foreach ($getUsers as $index => $user) {
        $userID = saveToDB($user, rand(1,1000));
        if($index == count($getUsers) && alreadyUsed($userID)) {
             reset($getUser);
             reset($index);
        }
}

This doesnt work

    foreach ($getUsers as $index => $user) {
    $userID = saveToDB($user, rand(1,1000));
    if ($index == count($getUsers) - 1 && alreadyUsed($userID)) {
        continue;
    }
    // Code...
}

    When the condition is met, the loop will skip the rest of the current iteration and start from the next iteration, thus restarting the loop.

    Sorry google translate 🙂

    The reset() function in PHP is used to reset the internal pointer of an array to its first element, but it doesn’t impact the control flow of a foreach loop, you could achieve desired behaviour, like this:

    $continueLoop = true;

while ($continueLoop) {
    foreach ($getUsers as $index => $user) {
        $userID = saveToDB($user, rand(1,1000));

        if ($index == count($getUsers) - 1 && alreadyUsed($userID)) {
            // If you reach the last user and the userID is already used,
            // continue the outer while loop
            continue 2;
        }
    }

    // If the end of the foreach loop is reached without restarting,
    // break out of the while loop
    $continueLoop = false;
}
