PHP支持回调的函数

1、匿名函数

$server->on('Request', function ($req, $resp) use ($a, $b, $c) {

    echo "hello world";

});

2、类静态方法

class A

{

    static function test($req, $resp)

    {

        echo "hello world";

    }

}

$server->on('Request', 'A::Test');

$server->on('Request', array('A', 'Test'));

3、函数

function my_onRequest($req, $resp)

{

    echo "hello world";

}

$server->on('Request', 'my_onRequest');

4、对象方法

class A

{

    function test($req, $resp)

    {

        echo "hello world";

    }

}

$object = new A();

$server->on('Request', array($object, 'test'));
