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‘));
