I cannot figure out why the program is not working. I am supposed to take each student object and use to assign_to_dorm function and add them to the dorm. and then print out all of the occupants in the array with the view_occupants function. All the program does is iterate one of the Dorm names and does nothing with the view_occupants. I’m not even sure if the Assign_to_dorm function is even working

    Your code looks ok to me, but I notice that Dorm::ocupants appears to be an array of Student objects. When you iterate over it in view_occupants(), you are echoing out the object directly. Unless it calls a __toString() magic method to produce output for echo, you won’t be displaying the information you intend.

    If my assumption is incorrect, please also post student.class.php.

      function view_occupants(){
      foreach($this->occupants as $resident){

       // Instead of echoing out the $resident obj, echo out a name:
       echo "<p>".$resident->lastname."</p>";
      }
    }
