Work

The Work module allow you to execute multiple jobs in parallel, via cooperative multitasking.

Notice:

This feature needs Generators, so PHP version must be at least 5.5 to be used, a fatal error is triggered if version requirement is not met.

Add a worker

---

Workers must be generators, so the yield keywords must be present. When a worker is registered, an object of class TaskCoroutine is returned.

Work::add(function(){
  for ($i = 0; $i <= 10; $i++) {
    echo "Value: $i \n";
    yield; // Pass control to other workers
  }
});

You can also assign a name to the worker :

Work::add('the_counter',function(){
  for ($i = 0; $i <= 10; $i++) {
    echo "Value: $i \n";
    yield; // Pass control to other workers
  }
});

Run and resolve all workers

---

All registered workers will be executed and the method will release control after all of the workers have finished their job.

Work::run();

Example

---

Work::add(function(){
  for ($i = 0; $i <= 20; $i++) {
    echo "A: $i \n";
    yield;
  }
});

Work::add(function(){
  for ($i = 0; $i <= 10; $i++) {
    echo "B: $i \n";
    yield;
  }
});

// Run the workers
Work::run();
