How to use CI/CD in PHP programming?

Nowadays, continuous integration/continuous delivery (CI/CD) has become a standard practice in software development. Its benefits are obvious: shortening the software development cycle, reducing error rates, improving software quality, etc. If you are programming in PHP, this article will introduce you to how to use CI/CD in PHP programming.

1. Continuous Integration (CI)

Continuous integration is a software development practice that identifies possible errors and technical debt through frequent inspection and testing of code. Thereby improving software quality. To use CI in PHP programming, you can take the following steps:

1.1. Submit code to the code library

Before using CI/CD, you need a code library to save your PHP code . Both GitHub and GitLab are very popular code repositories, you can choose the one you like.

1.2. Trigger the automation process

CI requires you to automatically start the automation process after the code is submitted. This process includes code compilation, unit testing, code static analysis and static inspection, etc.

1.3. Compile the code

Compiling the code is an important step to ensure that the PHP code runs on different platforms. In this step, you need to use a compiler to convert the code into machine language to ensure that the PHP code can run on various operating systems.

1.4. Running unit tests

Unit testing is a testing method that checks whether each individual component in the code runs correctly. In PHP programming, you can use PHPUnit for unit testing. During the CI process, you can add test cases to your code and have them run automatically every time the code is submitted.

1.5. Run code static analysis and inspection

In order to enhance code quality, you need to use some tools to perform static analysis and inspection of PHP code. Code static analysis and inspection can help you check for possible problems in the code, such as security vulnerabilities, bad code, etc. In PHP programming, you can use tools such as PHPStan and PHP_CodeSniffer to complete code static analysis and inspection.

2. Continuous Delivery (CD)

Continuous delivery is an automated process designed to automatically package software code into a standardized process before delivering the software to the production environment. form, and the software is gradually pushed to the production environment. In PHP programming, you can use CD to simplify the software deployment process and ensure that the software can run smoothly in different production environments.

2.1. Automated deployment

In continuous delivery, you need to use automated deployment to push the application to the production environment. You can use tools, such as Ansible and Puppet, to automate the deployment process. Using these tools, you can easily deploy applications to different servers.

2.2. Walkthrough

Before pushing the software to production, you need to conduct a walkthrough to ensure that the software will run correctly. You can run your application in a pre-release environment first and then test it before going into production to ensure software quality.

2.3. Monitoring

After pushing the application into production, you need to monitor to ensure that the application is running. There are tools you can use to monitor the performance and health of your application, such as New Relic and Datadog.

Summary

In PHP programming, CI/CD has become a necessary practice. Using CI/CD, you can shorten the software development cycle, reduce error rates, and improve software quality. Before using CI/CD, you need to commit the code to the code base and then trigger the automation process. In the CI process, you need to compile the code, run unit tests, run code static analysis and inspection, etc. During the CD process, you need to automate steps such as deployment, drills, and monitoring. I hope this article will be helpful to you and enable you to better use CI/CD to improve the quality of PHP programming.
