I'm still a novice to PHP and ORM stuff. I am trying to get an associative
object's data through the getter method. An event may contain 0 or more
collaborators. So for example, event "E0001" have 2 collaborators, I want
to retrieve that 2 collaborators' details and display it in the webpage.
However, an "Uncaught Error: Call to a member function getCollabID() on
string" error occurred when I invoked the "getCollabByEventID("E0001")"
method in "EventCollaboratorService.php".
The relationships for Events and Collaborators are illustrated in this link:

Codes:
Event.php: https://pastebin.com/ynkWQfhR
Collaborator.php: https://pastebin.com/LNgVQ8H7
EventCollaborator.php: https://pastebin.com/CQtKbrim
EventCollaboratorService.php: https://pastebin.com/vQz6x8Bp
<https://pastebin.com/vQz6x8Bp>
In the webpage file, the codes are as below:
> <?php
> $eventCollabs = new EventCollaboratorService();
> $eventCollabs = $eventCollabs->getCollabByEventID($_GET['e']);
> ?>
> <table>
> <thead>
> <tr><th>Collaborator ID</th></tr>
> ....
> </thead>
> <tbody>
> <tr><td><?php echo $eventCollabs[$i]->getCollaborator()->getCollabID();
> ?></td></tr>
> <tr><td><?php echo $eventCollabs[$i]->getCollaborator()->getCollabName();
> ?></td></tr>
> <tr><td><?php echo
> $eventCollabs[$i]->getCollaborator()->getCollabTypeString(); ?></td></tr>
> ....
> </tbody>
> </table>
>
>
> The records are unable to link to Collaborator.php. Which part did I did
wrong? Thank you.
