What are the implications of PHP not supporting parallelism in executing commands?

PHP not supporting parallelism in executing commands means that tasks cannot be run simultaneously, leading to potential performance bottlenecks and slower execution times. One way to solve this is by using multi-threading or asynchronous programming techniques to run tasks concurrently. 

// Example of using multi-threading with pthreads extension in PHP
class MyThread extends Thread {
    public function run() {
        // Code to be executed in parallel
    }
}

$thread = new MyThread();
$thread->start();
$thread->join();
