Call static function on array of types

Question

For example, I got the following classes: \App\User, \App\Profile and \App\Icon.
Every class got a static function creating which accepts a closure as paramter. Now I got an array of them:

$classes = [
   \App\User::class,
   \App\Profile::class,
   \App\Icon:class
];

Now I want to loop trough the array and call the creating function with a closure on every class. My problem is that I don't know much about the ::class keyword and how to use it proberly.

::class will just return the fully-qualified class name.

$classes = [
\App\User::class,
\App\Profile::class,
\App\Icon::class
];

Is the same (effectively) as:

$classes = [
   "\App\User",
   "\App\Profile",
   "App\Icon"
];

So it's iterable just like normal dynamic class names:

foreach($classes as $class){
   $class::creating($closure);
}

Maybe I would operate with the class names. Without having tried:

$classes = [
   'User',
   'Profile',
   'Icon'
];
foreach ($classes as $class) {
   \App\$class::creating($closure);
}
