如何动态地向php对象添加新方法？

您可以利用

__call

class Foo{    public function __call($method, $args)    {        if (isset($this->$method)) { $func = $this->$method; return call_user_func_array($func, $args);        }    }}$foo = new Foo();$foo->bar = function () { echo "Hello, this function is added at runtime"; };$foo->bar();
