将PHP函数的返回值输入SQL数据库

Question

I have this function:

public function post(){
    try{

        $con = connectDB();
        $sth = $con->prepare('SELECT * FROM posts');
        $sth->execute();
        $posts = $sth->fetchAll();

        foreach($posts as $post){ ?>

            <div>
                <h2><?php echo $post['title']; ?></h2>
                <p>
                    <?php echo $post['content']; ?>
                </p>
                <h6><?php echo $post['category']; ?></h6>
            </div>

        <?php }

    }catch(PDOException $e){echo $e->getMessage();}
}

And I want the return values of this function be stored in my database using my other function:

$page = new PageModel();
$post = new PostModel();

$page->addPage('Blog',$post->post());

But this one is not working. Can someone tell me what's wrong and if possible, suggest the most simple, possible way? Thanks!

Return the values to retrieve from other area

public function post(){
    try{

        $con = connectDB();
        $sth = $con->prepare('SELECT * FROM posts');
        $sth->execute();
        $posts = $sth->fetchAll();

        foreach($posts as $post){ ?>

            <div>
                <h2><?php echo $post['title']; ?></h2>
                <p>
                    <?php echo $post['content']; ?>
                </p>
                <h6><?php echo $post['category']; ?></h6>
            </div>

        <?php }

    }catch(PDOException $e){echo $e->getMessage();}

return $posts;
}
