In PHP forums, how do I parallelize workloads?

In PHP forums, parallelizing workloads can significantly enhance performance by allowing scripts to perform multiple tasks at the same time. This can be particularly useful for handling large data sets or performing multiple API calls. One common way to parallelize workloads in PHP is by using either multi-threading with extensions like pthreads or forking processes with the `pcntl_fork` function. Additionally, you can utilize asynchronous programming techniques with libraries like ReactPHP.

Description: Learn how to parallelize workloads in PHP to enhance performance and manage multiple tasks simultaneously using different methods including multi-threading and asynchronous programming techniques.


        <?php
        // Example of parallel processing using pcntl_fork
        $processes = [];
        
        for ($i = 0; $i < 5; $i++) {
            $pid = pcntl_fork();
            if ($pid == -1) {
                die('Could not fork');
            } elseif ($pid) {
                // Parent process
                $processes[] = $pid;
            } else {
                // Child process
                echo "Process {$i} is running\n";
                sleep(1); // Simulating some work
                exit(0); // Child exits
            }
        }
        
        // Waiting for all child processes
        foreach ($processes as $process) {
            pcntl_waitpid($process, $status);
        }
        
        echo "All processes completed\n";
        ?>
