swoole 4种PHP回调函数风格

匿名函数

$server->on('Request', function ($req, $resp) use ($a, $b, $c) {
    echo "hello world";
});

//可使用use向匿名函数传递参数

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'));

函数

function my_onRequest($req, $resp)
{
    echo "hello world";
}
$server->on('Request', 'my_onRequest');

对象方法

class A
{
    function test($req, $resp)
    {
        echo "hello world";
    }
}

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