Introduction to commonly used class libraries for PHP development in WeChat mini programs

With the continuous development of mobile Internet, the use of various Apps is becoming more and more common and the scale is getting larger and larger. As an emerging application form, WeChat mini programs are favored by more and more developers. And small programs developed in PHP have also become a trend. Under this trend, the use of common PHP class libraries has become more and more important. In the process of small program development, PHP class libraries are even more indispensable. In this article, we will mainly introduce the common class libraries used in PHP development in WeChat mini programs.

1. Commonly used class libraries for PHP development in WeChat mini programs

1. SDK class library

The SDK class libraries used in the development of WeChat mini programs include WeChat mini program SDK, WeChat public account SDK, WeChat open platform SDK, etc. Through these class libraries, we can implement various functions in WeChat applet development, such as obtaining user information, sending messages, generating QR codes, etc. At the same time, these SDKs are also relatively mature and easy for secondary development.

2. Web development framework

The frameworks used in WeChat applet development include ThinkPHP, Laravel, Yii, etc. These frameworks are widely used frameworks and have the following advantages:

(1) Highly modular design, easy to maintain and upgrade.

(2) Excellent router and view system make it easier for developers to control large applications.

(3) Rich plug-in and extension support can greatly simplify the code.

(4) Good object-oriented support can improve code reusability.

3. ORM class library

ORM (Object Relational Mapping) is a technology that maps relational databases to objects in object-oriented programming languages. The ORM class library includes Eloquent ORM and Doctrine ORM wait. ORM class libraries can greatly improve development efficiency, reduce developers' workload, and at the same time ensure data security.

4. Log library

The log library allows us to easily record program output to better debug the program. Commonly used logging libraries include Monolog, Log4php, etc.

5. Cache library

The cache library can greatly improve program running efficiency and reduce program response time. Commonly used caching libraries in WeChat mini programs include Memcached, Redis, etc.

6. 4D class library

The 4D class library can provide us with multi-dimensional graphic displays, such as bar charts, line charts, etc. Commonly used 4D libraries include pChart, eChart, HighCharts, etc.

7. ORM class library

ORM (Object Relational Mapping) is a technology that maps relational databases to objects in object-oriented programming languages. The ORM class library includes Eloquent ORM and Doctrine ORM wait. ORM class libraries can greatly improve development efficiency, reduce developers' workload, and at the same time ensure data security.

8. Image processing library

The image processing library can help us process images, such as image compression, watermark addition, image rotation, etc. Commonly used image processing libraries in WeChat mini programs include GD, ImageMagick, etc.

2. Summary

In the development of WeChat mini programs, PHP language is a very important development language. Commonly used development class libraries can greatly improve development efficiency, reduce development costs, and improve program quality and reliability. The class libraries introduced above are only part of them. In the future, more and more advanced class libraries will emerge to provide richer and more powerful tool support for WeChat applet developers.
