Getting Started with PHP: Git Version Management

As one of the most popular open source Web technologies, PHP has become one of the main languages ​​for Web development. It's easy to learn and use, and has a wide range of applications. In this article, we will focus on some basic knowledge and usage of Git so that PHP developers can manage their code more effectively.

Git is a distributed version control system used to manage code modifications and changes. It was created by Linus Torvalds and is widely used in the open source community. Git helps development teams easily track modifications, collaborate on projects, and retain historical records for backtracking and analysis.

The use of Git can be divided into the following steps:

1. Installing Git

Before using Git, you need to install it first. Git has installers for various platforms, which you can download from the official website. The installer installs Git's command line tools, which you can use on Linux, Mac, and Windows systems.

2. Create a code repository

Before managing the code, you need to create a code repository for your project. A code repository is a Git repository that stores your code and history. You can create a code repository with the following command:

$ git init

This will create a new Git repository in the current directory. If you want to create a code repository in a new directory, use the following command:

$ git init myproject

This command will create a Git repository in a new directory named "myproject".

3. Add and commit changes

Before making any changes in your project, you need to add all files to the Git repository. You can add all files with the following command:

$ git add .

This will add all files that are not added to the repository. Next, you need to commit your changes and create a new commit record:

$ git commit -m "Commit message"

This will commit your changes and create a new commit record. In the commit record, you should include meaningful information about the changes made by the commit. This allows others to understand the purpose of the commit and the changes made.

4. View History

One of the main features of managing code is the ability to view history and analyze modifications. Git makes viewing history very easy. You can view all commit records in the project through the following command:

$ git log

This command will display all commit records in the project, including author, commit time and commit message.

You can also use a number of different flags to filter and sort commit records. For example, you can use the following command to view only the last 5 commit records:

$ git log -5

5. Create branch and merge changes

a An important Git feature is the ability to create new branches, which are copies of a project. You can make changes in a branch without affecting the original code. Here's how to create a branch:

$ git branch newbranch

This command will create a new branch named "newbranch". Next, you can switch to this branch and make changes:

$ git checkout newbranch

After the changes are complete, you can merge the branch back into the master branch:

$ git checkout master
$ git merge newbranch

This will merge your changes in the master code. If conflicts exist, Git will prompt you to resolve them.

6. Remote repositories and commits

In order to collaborate with others, you need to push your code to the remote repository. You can push code to the remote repository using the following command:

$ git push origin master

This will push the code from the master branch in the remote repository named "origin". If you are using your code repository with a hosting service such as GitHub, you will need to add it to the hosting service using the guidelines for creating a new repository. Once added, you can push local code to remote repositories and collaborate.

Summary

In this article, we have learned about Git and some of its basic knowledge and usage in PHP. Git is a very powerful tool that can help manage code changes during team development. By mastering the basics of Git, you'll be better able to collaborate and manage your PHP projects.
