Basic learning route of PHP

This article mainly introduces you to the route on how to start learning PHP. The steps are more detailed. I hope it will be helpful for everyone to get started with PHP.

Many people have published too many PHP learning roadmaps on the Internet. I have worked in Internet companies for more than ten years and have brought many novices to PHP. I have compiled some of their questions and learning roadmaps for everyone. Come out, I hope many newbies will avoid detours.

1. Some erroneous learning roadmaps on the Internet

There are some erroneous learning roadmaps on the Internet that ask you to learn Javascript and jQuery immediately after learning HTML and CSS. This kind of course is simply Play the piano to the cow. Why the hell don’t you get a front-end engineer training or a bragging full-stack engineer training?

The problem with this wrong roadmap is that the focus is not on the PHP direction, but on the front-end direction. The focus of PHP such as object-oriented, business thinking, SQL transformation, etc. is not placed before but after. The focus of PHP is still on business processing.

2. Accelerate the entry in the early stage

In the early stage, you need to speed up the entry progress. After you learn some HTML and Css and can basically write web pages, you can quickly enter the PHP stage.

Because everyone is self-taught in PHP, if you haven’t mastered PHP after learning for a long time, you will lose your enthusiasm for learning, resulting in a decline in the effectiveness of self-study.

Don’t learn Js after learning HTML and Css, and immediately start building the environment.

3. About the development environment

Many people take detours here and like to find that they can’t find the same tutorial to build the environment. When we develop in the company, we really use the Linux environment for development and online code running.

In the process of learning, I suggest: fast, fast, fast. Just worry less and the code can run.

Here, it is recommended to use XAMPP, AppServ, PHPStudy, WampServer and other tools to quickly install and start your first paragraph

<?php
?>
phpinfo();

4. Basic syntax

The environment is set up , the things you need to learn at the beginning include the following things: variables, data types, comments, constants, if...else, switch...case, while, do..while, for, operators, arrays, functions, common functions;

During these processes, many novices tend to wonder why they can’t write anything.

In addition, they are all basic grammar, which must be remembered. Write more, remember more and memorize more.

It’s normal to feel like you can’t write anything psychologically.

5. Process-oriented usage stage

You can write things at this stage. After learning the MySQL database, start learning PHP to connect to the database immediately. After learning, write a guest book , paging, and then learn a cookie and session to implement user login and registration. After learning GD, start implementing a verification code.

Finally at this stage you can write a forum, post bar or shopping mall.

6. Object-oriented and MVC

Don’t watch PHP5 videos at this stage. It’s best to watch PHP7 and later videos, especially new standards, such as: composer, PSR, Object-oriented design patterns, etc. You can watch some of Qianfeng PHP’s latest videos, which cover all these technical points.

The order of learning in this section:

1. Basic object-oriented syntax;

2. Write a few common classes;

3. Combined MVC

4. Learning design patterns

5. ##Learning PSR

7. Learn the front-end in depth

After learning PHP, the front-end course will be like playing. Because you already have the foundation of a language. So, learn some JS, then learn some jQuery, bootstrap is enough for you.

8. Go deep into ThinkPHP5.0 or Laravel

Learn one or two frameworks in depth, and then combine the front-end knowledge to write two or more projects.

You can write a multi-category mall, write an OA system, etc.

9. Learning Linux Server

The main purpose of learning Linux server is to understand the deployment of multiple servers and understand software installation, especially the environment construction of LAMP and LNMP.

Build the corresponding code to the server you deployed.

Finally, it will be better to buy a domain name and Alibaba Cloud server, actually deploy the code to the cloud server, go through the online process, and use git to manage the code.

10. In-depth study of large concurrency architecture

It is very necessary for you to learn about large concurrency architecture and learn some NoSQL technology, Swoole technology, keepalived technology and many other different technologies.

Let yourself fully understand how the code under the server cluster runs more efficiently.

And a comprehensive understanding of PHP's socket, process, thread, coroutine and other technologies will be very helpful for the technical improvement of your code.

It is recommended to use Redis and RockMQ to write a large concurrent, multi-server flash sale at this time.

There are a lot of videos about this in China. Don’t watch PHP5 videos anymore. You can watch more PHP7 videos, as well as some big domestic institutions like: Qianfeng PHP’s large concurrency cluster technology .
