Laravel Example: Cache Locking

If you make use of the Laravel framework, here is a code example from Taylor Otwell on how to use cache locking.

try {
    $lock = Cache::lock('foo', 10)->block(5);

    // Lock acquired after waiting maximum of 5 seconds...
} catch (LockTimeoutException $e) {
    // Unable to acquire lock...
} finally {
    optional($lock)->release();
}
