php-symfonyHow to use mutex in PHP Symfony?

A Mutex is a synchronization mechanism used to ensure that only one thread can access a shared resource at a time. In PHP Symfony, Mutex can be used to protect critical sections of code from concurrent access.

Example code

$mutex = new \Symfony\Component\Lock\Mutex('my_lock');

if ($mutex->acquire()) {
    // critical section of code
    $mutex->release();
}

The example code above will acquire a lock on the resource named 'my_lock' and execute the critical section of code. Once the critical section of code is finished, the lock is released.

Code explanation

1. $mutex = new \Symfony\Component\Lock\Mutex('my_lock'); - This line creates a new Mutex object with the name 'my_lock'.

2. if ($mutex->acquire()) { - This line attempts to acquire a lock on the resource named 'my_lock'.

3. // critical section of code - This is the critical section of code that should be protected from concurrent access.

4. $mutex->release(); - This line releases the lock on the resource named 'my_lock'.
