Error with class array

A while ago I was trying to learn PHP OOP by using classes to make a simple forum system. I have a function that will return an array of Post objects. The problem I'm having is I tried to loop over them and call a function, but for some reason PHP is treating them like a number. I have it check if the object is an instanceof Post yet it doesn't work.

Heres a snippet of my code:

PHP Code:
$posts = Database::LoadPosts(isset($_GET['page']) ? intval($_GET['page']) : 1);

  for($i=0; $i < sizeof($posts); $i++){
    $post = $posts[$i];
    if($post instanceof Post) {
      echo $post->GetHTML();
    }
  }

I believe your error will be within the LoadPosts function. I believe you can only store stdObject and instantiated objects within an array.

I quick tip, I would be using a foreach loop to loop through the objects and not an iterator like you've got, i.e.

Code:
$posts = array([objects]);
 
 foreach($posts as $key=>$post_object){
 
        $post_object->object_function();
        $posts[$key][change something in the original array] = []; 
 
 }
