What are alternatives to Semaphore and how do they compare?

Alternatives to Semaphore include Mutexes, CountDownLatch, and CyclicBarrier, which provide different mechanisms for achieving synchronization in concurrent programming. These constructs each have unique advantages and use cases, such as controlling access to critical sections, managing threads' waiting conditions, and allowing threads to wait for each other in a controlled manner.

        <?php
        // Example of using Mutex as an alternative to Semaphore

        class Mutex {
            private $locked = false;

            public function lock() {
                while ($this->locked);
                $this->locked = true;
            }

            public function unlock() {
                $this->locked = false;
            }
        }

        $mutex = new Mutex();

        // Thread 1
        $mutex->lock();
        // Critical section
        $mutex->unlock();

        // Thread 2
        $mutex->lock();
        // Critical section
        $mutex->unlock();
