PHP Git practice: How to use Git to improve code quality and team efficiency?

Git is a distributed version control system that helps manage code changes and collaborate on development. It allows tracking changes, collaborating with others, and merging branches. In addition, code review, automated deployment, and the ability to roll back changes are provided to improve code quality and team efficiency.

PHP Git in practice: improve code quality and team efficiency

Git is a distributed version control system that can help you Track and manage code changes and collaborate with other developers. By using Git, you can:

• Track code changes and easily roll back changes
• Collaborate with other developers
• Easily merge changes into the master branch
• Manage and resolve code conflicts

Installing Git

Before you start using Git, you need to install it on your system. You can visit the official Git website ([https://git-scm.com/](https://git-scm.com/)) to download and install the version for your operating system.

Create a Git repository

To create a Git repository, navigate to the directory where you want to track code changes and run the following command:

git init

This will create a hidden directory called .git that contains all the information Git needs to track code changes.

Add files to Git repository

To add files to Git repository, use the git add command. For example, to add the index.php file to the repository, run the following command:

git add index.php

Commit changes

To commit changes, use git commit command. The commit contains a message describing the changes you made. For example:

git commit -m "Added index page"

Push changes to a remote repository

To push changes to a remote repository such as GitHub or GitLab, use git push Order. First, you need to create a remote repository and add it to your local repository. Here's how to push changes to a GitHub repository named my-repo:

git remote add origin https://github.com/username/my-repo.git
git push -u origin master

Pull remote changes

To pull from the remote repository To retrieve changes, use the git pull command. For example, the following command pulls changes from the my-repo repository:

git pull origin master

Merge changes

If you and others are working on the same file at the same time If you make changes, conflicts may occur before the changes are merged. To resolve conflicts, use the git merge command. Git will show you the conflicting parts and you'll need to resolve them manually.

Branch

Branching allows you to experiment with code changes without affecting the main branch. To create a branch, use the git branch command. For example, to create a branch named feature/new-feature, run the following command:

git branch feature/new-feature

Changes can be made on the branch and merged with the master branch.

Practical examples of using Git

Code review

Git allows you to use code review tools such as GitLab CI/CD or GitHub Actions, for automated or manual review of code changes. This can help identify and resolve issues and prevent errors from being merged into the master branch.

Automated deployment

You can use Git CI/CD tools to automate the code deployment process. This saves time and ensures consistent deployment.

Rolling Back Changes

If you need to roll back changes due to errors or other reasons, you can use the git reset command. For example, to roll back to the previous commit, run the following command:

git reset --hard HEAD~1
