Editor to share with you the example analysis of Symfony core classes, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

The details are as follows:

Core classes of Symfony

Symfony's MVC method uses some classes that you will often encounter later.

1. SfController is the controller, which decodes the request and delivers it to the action

2. SfRequest stores all request elements (parameters, Cookies, header information, etc.)

3. SfResponse contains response header information and content, which are eventually converted to HTML and given to users.

4. A context (obtained through sfContext::getInstance ()) holds references to all core objects and existing configuration information, and it can be accessed anywhere.

As you can see, all symfony classes use the sf prefix, which avoids conflicts with your own classes or variables and makes the core framework's classes easy to identify.

Organization of code

You already know the different components of the symfony app, but you may not know how it is organized.

Project structure: applications, modules, and actions

In symfony, a project is a set of services and operations under a defined domain name that share an object model.

A project is composed of multiple applications, an application is composed of multiple modules, and a module can contain multiple actions.

Project structure diagram:

Root Tree structure and description of Symfony

Apps/

Contains the application of the project, each application corresponds to a folder

Batch/

Contains PHP code for command line execution or scheduling

Cache/

Cache folder, requires permission of 777

Config/

Save the basic configuration of the project

Data/

The data file that stores the project, such as the database structure, the SQL file that creates the data table, or the database file of SQLite.

Doc/

Store project documents, including your own and documents generated by PHPDoc

Lib/

Data model

Log/

Log folder, which requires 777 permissions

Plugins/

Store plug-ins installed in the application

Test/

Half-time unit and commonality test

Web/

Root of the WEB service
