在PHP中将对象作为参数发送，而不进行实例化

How to send an object as paramater in a function call? I don't want to instantiate the object when passing it, so myFunction( new myObject() ) wouldn't work.

I want myFunction to be able to instantiate the object later. I'm just not sure how to pass a class around in this manner.

You could pass a string and do:

myFunction($class) {
    $object = new $class();
}

But a better OOP approach would be to pass a factory object and let the factory create the object:

class MyFactory {
    public function create() { 
        return new myObject; 
    }
}

myFunction(MyFactory $factory) {
    $object = $factory->create();
}

Pass the class name as a string, and instantiate it.

function ($className) {
    $object = new $className();
}
