Cannot declare class \Content, because the name is already in use - php

Question

I've setup my server with Yii2 and Humhub ext,
What i'm trying to do is set a rest api to it , but I get 500 Internal server error :
"message": "Cannot declare class humhub\modules\content\models\Content, because the name is already in use",
"file": "***\content\models\Content.php",
The first class is :
<?php
namespace app\models;
use Yii;
include '../humhub/modules/content/models/content.php';
class Content extends \humhub\modules\content\models\Content
{
public function getPosts()
{
return $this->hasMany(Post::className(), ['id' => 'object_id']);
}
}
The second class is (pretty big):

As you can see the first class extends the second one , I'm rather new to php but i'm guessing that's the issue
UPDATE : I tried using the "use class as " and still the same error , I also tried changing the name of the first class to Content1 just to check and still the same .
The problem occours in the second class from the error report
This is a recurring error in a few places in the server I figure I will solve it here and the rest will be the same ,
Many Thanks!

You included file with exacly same class name, so you have 2 class declarations with name Content in this file. Easiest ways to fix it:
Change one of class name
Start using Yii2 autloader, if you need to include something - there's something wrong in your code. You should be able to access
class only by using namespace. There's small conditions you have to
met:
Each class must be under a namespace (e.g. foo\bar\MyClass)
Each class must be saved in an individual file whose path is determined by the following algorithm:
// $className is a fully qualified class name without the leading backslash
$classFile = Yii::getAlias('#' . str_replace('\\', '/', $className) . '.php');
