Tutorial

1. Use Worker

Use Worker\Worker

2. Using Anonymous Function

$worker = new Worker(
    // Here you can provide your main callback
    function($arg1 = '', $arg2 = '') {
        file_put_contents('result.txt', $arg1 . $arg2);
    },
    // The second one is used when main callback has completed successfully
    function() {
        file_put_contents('success.txt', 'success');
    },
    // If an exception has happened in the main callback then this callback will be called with an error message
    function($e) {
        file_put_contents('error.txt', 'error');
    }
);

// Start the worker, and pass 2 arguments to the main callback. It is also possible to pass more arguments
$worker->start('first arg', 'second arg');

3. Using Class Object Method

class SomeClass
{
    public function method($arg1, $arg2, $arg3)
    {
        file_put_contents('result.txt', $arg1 . $arg2 . $arg3);
    }
};

And then somewhere:

$object = new SomeClass();
// Pass array, first item is the object and second item is the name of the class method
$worker = new Worker([$object, 'method']);
// Start worker and send 3 arguments
$worker->start('from', ' object method', ', this is nice');

4. Using Class Static Method

class SomeClass
{
    public static function method($arg1, $arg2, $arg3)
    {
        file_put_contents('result.txt', $arg1 . $arg2 . $arg3);
    }
};

And somewhere:

$worker = new Worker(__NAMESPACE__ . '\SomeClass::method');
$worker->start('from', ' class method', ', nice');
