//Your class instance
$myObj = new MyObj();
//You can add one $before and one $after there,
//or add after
$demo = new AOP($myObj);
$demo->addBefore(function($method, $arguments) {
    //do something
    //$method and $arguments recv the method(argument[])
});
$demo->addAfter(function($result, $method, $arguments) {
    //do something
    //$result recv the return of method(argument[])
});
$demo->myFunc(...something...);

Method 2

You can just write your class that extends the AOP class, then you can get IDE's automatic prompt.

Standard

$before and $after must return a bool.

thrown
