Give PHP function class object

Question

Is it possible to call a function and supply it with a class? Something like:

function foo(class $class) {
  // do something with the class
  echo $class->id;
}

// calling the function
foo(class Bar {
  // supplying the class
  public $id, $username, $password, $time, $ip;
});

No, you can't supply a class definition. You can supply an instantiated object of that class. — Jonnix

@JonStirling Yeah I knew about the instance of a class, but thanks for confirming :-) — Jack Hales

@Jek your example makes no sense, compared to your question. It looks like you really want the instance of a class. (You do echo $class->id, that would NOT be possible on a class definition because theres no instance?) — xate

Your example is a little confusing but I think you are looking for an anonymous class:

function foo($class) {
    echo $class->id;
}

foo(new class {
    public $id;
});

Note that anonymous classes are available only for PHP 7+
