In the early stage of learning, the main basic knowledge of WEB front-end, such as a simple understanding of html5/css3/java/jquery, can be written through html5 div css3 A basic WEB front-end static page will suffice. We recommend several mainstream WEB front-end frameworks, such as bootstrap/foundation/pure and other WEB front-end frameworks, which can be later used as learning projects in PHP introductory tutorials. You can choose according to your personal later development plan. The basics of front-end development play a certain role in getting started with later learning.

Quick Start

After a simple understanding of some basic elements of WEB front-end development, you can better achieve a quick start with PHP, without the need for java/jquery/ Study the bootstrap tutorial in depth to determine the direction of PHP learning as early as possible, such as: basic syntax, basic framework, variables, arrays, PHP custom functions, PHP environment variables and other syntax. In the quick entry stage, it is not required to deeply expand the knowledge. It is enough to have a certain concept. In the early stage of learning, it is definitely unrealistic to understand.

Development Environment

Many novices are a little blind during the learning stage and don’t know Where to start? I don’t know the process of setting up a PHP development environment, let alone the instructions for using the PHP development environment. This is determined based on the current operating system, such as ubuntu/Linux/windows systems, etc. The development environment tools are slightly different. Some commonly used development environments include: wampserver/appserv/xampp/lampphpstudy and other one-click building tools.

Basic syntax

After the environment is set up, you must prepare to quickly get started with the basic syntax of PHP: loop statements, flow control statements, variables, data types, comments, static constants , anonymous functions, PHP operators, arrays, commonly used functions, etc. For basic grammar, you should first roughly remember some concepts and basic definitions. As for the actual application of basic grammar, you have to continue to practice and consolidate it through examples later.

Example tutorial

After you are proficient in the basic syntax and development environment of PHP, you can consider example applications. After all, it will be difficult to consolidate and deepen your memory without practical learning. After initial learning of MySQL database, you can learn PHP to connect to the database. After learning, you can develop blog guestbook and website paging functions. Cookies and sessions can realize user login and registration functions. After taking the time to learn PHP's GD, I started to implement the verification code.

Framework Learning

In order to facilitate the company's various complex site functions, you need to master one or two of the mainstream PHP frameworks. During the learning and development process, it is very difficult to Good to improve work efficiency. Common PHP frameworks include thinkphp/laravel/ci/yii.

Linux server learning

Linux server is very popular in the market. When users learn server configuration and deployment, most of them consider Linux server, LAMP or LNMP environment construction, and program writing. After completion, how to set it up on the server deployed by yourself. It is a necessary task for learning PHP. The prerequisite is to have your own domain name and server, complete domain name resolution, server space binding, configuration and deployment. GIT code management can make you familiar with the entire process faster.

Highly available and large concurrency architecture learning

In the middle and late stages of PHP learning, you must learn more about large concurrency architecture, NoSQL/Swoole/keepalived technology and many other different technologies . Let yourself have a comprehensive understanding of how the code can run better under the server cluster. A comprehensive understanding of socket, process, thread, coroutine and other technologies is very helpful for learning and improvement. Large concurrent processing of server clusters is the focus of later research.
