Cakephp 3.0教程很难[关闭]

Hi I'm a novice in cakephp and also I just finished reading the book "Php and Mysql for Beginners" by Lassoff.

So I'm totally newbie at programming.

However, I'm trying to make my blog with cakephp 3.0 which is newest version, I got stuck understanding some codes in the tutorial.

For example,

// src/Controller/ArticlesController.php

namespace App\Controller;

class ArticlesController extends AppController {

    public function index() {
        $articles = $this->Articles->find('all');
        $this->set(compact('articles'));
    }
}

I have no idea about the last two lines of code.

What i know is $article(variable) is declared and will store something by $this->Srticles->find('all')

and I don't know what is $this means and what is set() and what is ->

Please let me know or would you recommend something to read? like a book or something?

Thank you for your help.

Let me clarify :

cakePHP uses Object Oriented coding .Uses ORM for Database mapping. Object Relationship Model means it treats Table record as object.

1)

  $articles = $this->Articles->find('all');

Means For current Object , Goto table article which get associated by Model name Article ,And find All records.Store it in $articles. Its like SELECT * FROM articles.

2)

 $this->set(compact('articles'));

Here data fetched by current object Is set to send to view to render.And compact creates array from object.
