How to use multi-threading in PHP applications?

Sometimes, we want to use multi-threading in PHP applications.

In this article, we’ll look at how to use multi-threading in PHP applications.

How to use multi-threading in PHP applications?

To use multi-threading in PHP applications, we can create a Thread subclass.

For instance, we write

class AsyncOperation extends Thread {

    public function __construct($arg) {
        $this->arg = $arg;
    }

    public function run() {
        if ($this->arg) {
            $sleep = mt_rand(1, 10);
            printf('%s: %s  -start -sleeps %d' . "\n", date("g:i:sa"), $this->arg, $sleep);
            sleep($sleep);
            printf('%s: %s  -finish' . "\n", date("g:i:sa"), $this->arg);
        }
    }
}

$stack = array();

foreach ( range("A", "D") as $i ) {
    $stack[] = new AsyncOperation($i);
}

foreach ( $stack as $t ) {
    $t->start();
}

to create the AsyncOperation class which is a subclass of the Thread class.

In the class, we add the run method that runs some code.

Then we create the $stack array and populate it with AsyncOperation objects.

And then we use a foreach loop to start the threads with start.

Conclusion

To use multi-threading in PHP applications, we can create a Thread subclass.
