How to develop small programs in PHP?

PHP is a very popular server-side scripting language that is widely used in the development of web applications. With the popularity of small programs, more and more PHP developers are trying to use PHP to develop small programs. So, how to develop small programs in PHP? Next, let’s discuss it.

1. Basic Concepts of Mini Program Development

Before starting to develop mini programs, let’s first understand the basic concepts of mini programs.

(1) Mini program

Mini program is an application form under the WeChat ecosystem. It is an application that can be used without downloading and installing. It has fast startup speed, Features include small footprint. Mini programs can provide users with specific services and functions, such as shopping, social networking, games, etc.

(2) Mini Program Development Tool

The Mini Program Development Tool is an integrated development environment for mini program development, which provides the functions of writing, debugging and publishing mini programs. WeChat officially provides mini program development tools, which developers can download and use from its official website.

(3) Mini program framework

The mini program framework is a set of development tools and APIs used to implement the functions and interfaces of mini programs. The mini program framework provides a wealth of components and APIs, with which developers can quickly develop mini programs.

2. Mini program development process

The mini program development process can be divided into the following steps:

(1) Register a mini program account

Developers first need to register a WeChat mini program account. After successful registration, you can log in to the mini program backend to manage and publish mini programs.

(2) Download the mini program development tool

The mini program development tool provided by the official website can provide automatic compilation, error prompts, debugging and other functions during the development process to improve development efficiency. Developers can download the mini program development tools from the WeChat official website according to their own operating systems. After installation, they can log in to their WeChat account to develop.

(3) Create a mini program project

Use the mini program development tool to create a mini program project and fill in the name, AppID and other information of the mini program.

(4) Write mini program code

Write mini program code in the mini program development tool, including HTML, CSS and JavaScript code.

(5) Debugging Mini Program

In the mini program development tool, you can use the debugging tool to debug and preview the mini program, find and solve problems.

(6) Publish the mini program

After the mini program is developed, it can be submitted for review in the mini program background. After passing, it can be published to the WeChat mini program platform for users to use.

3. Steps to develop small programs in PHP

To develop small programs in PHP, you need to follow the following steps:

(1) Install the PHP framework

You can use PHP framework to quickly build the back-end part of the mini program, such as Laravel, YII, etc. Developers can choose the required framework to install according to their needs.

(2) Build a back-end API interface

The applet needs to obtain data through the back-end API interface, so it is necessary to build a back-end API interface for the applet to call. Developers can use the API development functions provided by the PHP framework, or write their own API interfaces.

(3) Write the mini program code

Write the mini program code in the mini program development tool and call the back-end API to obtain data. Developers need to be familiar with the use of mini program frameworks and API interfaces, and understand the development specifications and characteristics of mini programs.

(4) Debugging Mini Program

In the mini program development tool, use the debugging tool to debug the mini program, find and solve problems. Conduct a complete test to ensure that the applet can run normally.

(5) Publish the mini program

After the development of the mini program is completed, upload the code and submit it for review. After passing the review, the mini program can be published to the WeChat mini program platform for users to use.

4. Summary

The above are the basic steps for developing small programs in PHP. The development of small programs requires mastering HTML, CSS, JavaScript and other technologies, as well as good development experience and the support of development tools. In addition, small programs require the cooperation of both the front end and the back end, so developers need to pay more attention to collaboration. Through exploration in actual development, we can better understand the application scenarios of PHP and become more proficient in using PHP for small program development.
