PHP Git practice: How to use hooks in code management and collaboration?

Git hooks can automate tasks in code management, including: Pre-commit hooks: perform actions, such as unit tests, before committing code. Post-push hook: perform operations after the code is pushed to the remote warehouse, such as automatically deploying to the production environment. Post-merge hooks: Perform actions when merging code, such as sending notification emails.

PHP Git Practical Combat: The use of hooks in code management and collaboration

Git hooks are powerful tools that can be used in Git operations (such as commit, push , merge) automatically execute custom actions when they occur. In PHP projects, hooks are particularly useful because they allow you to automate tasks in code management and collaboration processes.

Installing Git Hooks

First, make sure you have Git installed and configured for use with your PHP project. To install the hook, you need to create a file with the following content:

# 文件名：my-hook.php

<?php
// 此处添加您的钩子逻辑

Copy this file to your .git/hooks directory and change the file name to reflect the hook type name, such as pre-commit or post-push.

Pre-commit hook

Pre-commit hook allows you to perform actions before committing your code. For example, you can use pre-commit hooks to run unit tests or code formatting tools. Here is an example:

<?php
$result = shell_exec('phpunit');
if ($result !== '') {
    echo "错误：单元测试失败。" . PHP_EOL;
    exit(1);
}

Post-push hooks

Post-push hooks allow you to perform actions after the code has been pushed to the remote repository. For example, you can use post-push hooks to automatically deploy code to production. Here is an example:

<?php
$remote_url = $_SERVER['SSH_ORIGINAL_COMMAND'];
if ($remote_url === 'refs/heads/master') {
    shell_exec('rsync -av --delete . /path/to/production');
}

Post-merge hook

Post-merge hook allows you to perform actions while merging code. For example, you can use post-merge hooks to send notification emails or redeploy code. The following is an example:

<?php
if ($_SERVER['GIT_REF_NAME'] === 'refs/heads/master') {
    mail('example@email.com', '代码已合并到 master 分支', '代码已合并到 master 分支。请查看。');
}

Practical case

Consider the following practical case:

• Automatically run unit tests:Use pre-commit hooks to run unit tests before committing code to prevent faulty code from entering the code base.
• Automatic deployment to production environment: Use post-push hooks to automatically deploy code when it is pushed to the production branch, reducing manual deployment errors.
• Send version control notifications: Use post-merge hooks to send email notifications when branches are merged to notify team members for code review.

By using Git hooks, you can automate tasks in your code management and collaboration processes, saving time, improving code quality, and simplifying collaboration.
