How to use GitHub Actions for automated packaging and deployment of PHP programs?

Introduction
With the rise of cloud computing and DevOps, automation and continuous integration of software development have become increasingly important. GitHub Actions is a powerful automation tool that helps developers achieve rapid and efficient software development and deployment. In this article, we will focus on how to use GitHub Actions for automated packaging and deployment of PHP programs to improve development efficiency.

1. Set up GitHub Actions workflow
To use GitHub Actions, you first need to create a folder named ".github/workflows" in the root directory of the project. Create a YAML format file in this folder and name it "ci.yml". This document will define the workflow and specific steps.

The following is the content of an example ci.yml file:

name: CI

on: [push]

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
    - name: Checkout code
      uses: actions/checkout@v2

    - name: Set up PHP
      uses: shivammathur/setup-php@v2
      with:
        php-version: '7.4'

    - name: Install dependencies
      run: composer install

    - name: Run tests
      run: composer test

    - name: Build application
      run: composer build

    - name: Deploy to server
      uses: easingthemes/ssh-deploy@v2
      with:
        server: ${{ secrets.SERVER }}
        port: ${{ secrets.PORT }}
        username: ${{ secrets.USERNAME }}
        password: ${{ secrets.PASSWORD }}
        source: 'dist/'
        target: '/var/www/html'

In the above example, we defined a job named "build", which contains a series of steps. First, we check out the code from the code repository, then set up the PHP environment, install dependencies, run tests, build the application, and finally deploy the built application to the server.

It is worth noting that the deployment step uses an Action called "ssh-deploy", which is an open source deployment tool that can help us deploy code to a remote server. We need to set some environment variables in the "Settings" of the GitHub repository for use during deployment. For example, we need to set the server's address, port, user name, password and other information.

2. Code packaging and deployment
In the workflow of GitHub Actions, we can implement code packaging and deployment by executing different commands. The specific implementation process varies from project to project. The following example is a common practice:

# 打包
composer build

# 部署
uses: easingthemes/ssh-deploy@v2
with:
  server: ${{ secrets.SERVER }}
  port: ${{ secrets.PORT }}
  username: ${{ secrets.USERNAME }}
  password: ${{ secrets.PASSWORD }}
  source: 'dist/'
  target: '/var/www/html'

We first use the composer command to build the application (composer build) and generate the required packaging files. Then use the ssh-deploy Action to deploy the packaged files to the remote server. It should be noted that we use environment variables to save server-related information during the deployment process.

Before performing the deployment steps, ensure that the correct environment variables such as server address, port, username and password are set. These environment variables can be set in "Settings" - "Secrets" of the GitHub repository.

3. Enable GitHub Actions
Once we have completed the definition of the workflow and the packaging and deployment of the code, we can enable GitHub Actions to automate these tasks.

In the "Actions" tab of the GitHub warehouse page, we can see the defined workflow "CI". If it appears gray, it means the workflow is not enabled; if it appears green, it means the workflow is enabled.

When we commit code (push), GitHub Actions will automatically run the workflow and execute the steps. We can view the run log and the execution of each step in the "CI" workflow page under the "Actions" tab.

By enabling GitHub Actions, we can realize automated packaging and deployment of PHP programs, improving development efficiency and deployment speed. No manual work is required, and the workflow is automatically triggered with every code submission, simplifying the developer's workflow while reducing the risk of human error.

Conclusion
This article introduces how to use GitHub Actions for automated packaging and deployment of PHP programs. By defining the workflow and setting the appropriate steps, we can easily automate the packaging and deployment of code. At the same time, we also mentioned how to use the open source deployment tool "ssh-deploy" to deploy remote servers.

GitHub Actions not only supports PHP projects, but can also be used for project development and deployment in other languages. With this powerful tool, developers can focus more on code development and optimization, improving work efficiency and software quality.
