How can PHP developers efficiently break out of nested loops without terminating all loops?

When a PHP developer needs to break out of nested loops without terminating all loops, they can use a combination of labels and the "break" statement. By assigning labels to the outer loops, developers can specify which loop they want to break out of without affecting the others. This allows for more precise control over loop termination.

$found = false;

// Outer loop
for ($i = 0; $i < 3; $i++) {
    // Inner loop
    for ($j = 0; $j < 3; $j++) {
        if ($j == 1) {
            $found = true;
            break 2; // Break out of both loops
        }
    }
}

if ($found) {
    echo "Element found!";
} else {
    echo "Element not found.";
}
