Force variable pass as object

I need to define the type of passed variable as an generic object, how?

Tried:

public function set($service = null, (object) $instance) {
    [..]
}

Can stdClass help? How?

Thanks!

Gabriel,

if what you want to do is check if the variable is an object, you could do this:

public function set($service = null, $instance) {
    if (!is_object($instance)) return null; //or whatever
    [..]
}

What are you trying to prevent with that? With your declaration, you would get an exception if the variable is not an object (it will not cast it).

No, the object has to be some class. You can give the any class name as object's type

public function set($service = null, ClassName $instance) {
    //now the instance HAS to be the object of the class
}

Or a basic trick would be to create a basic class yourself

Class GenericObject {}
$myobj = new GenericObject();
$myobj -> myCustomVar = 'my custom var';

//Now send it
public function set($service = null, GenericObject $instance) {
   [...]
}

Nope, in php all classes aren't derive from the common ancestor.

So doubtfully you can use current php's implementation to state "object of any class"
