PHP study notes: version control and code management

Introduction:
In the process of software development, version control and code management are very important links. Through the version control system, developers can effectively manage code versions and conduct collaborative development. As a popular server-side scripting language, PHP also requires the use of a version control system to manage code. This article will introduce the basic concepts of version control and provide specific code examples to help readers better understand and apply version control and code management.

1. The basic concept of version control
1.1 The concept of version control
Version control (Version Control) refers to the process of managing files, code or any modified text. Through the version control system, we can record and track changes to files, view historical versions of files, and conduct multi-person collaborative development, etc.

1.2 Advantages of version control
The version control system can bring the following advantages:

  • Automatic backup and recovery: You can restore to the previous version at any time to avoid code loss.
  • Multi-person collaboration: Multiple people can develop the project at the same time, and the system will automatically merge their modifications.
  • Better code management: You can easily view historical versions and analyze code evolution and improvement points.
  • Branch management: You can create branches for different experiments and development, and finally merge them into the main branch.

2. Introduction to version control system
2.1 Git
Git is a free, open source distributed version control system. It is one of the most popular version control systems currently available. The following are some basic command examples of Git:

  • Initialize a Git repository

    $ git init
    Copy after login
    Copy after login
  • Clone a repository on Github

    $ git clone <URL>
    Copy after login
  • Add files to version control

    $ git add <file>
    Copy after login
    Copy after login
  • Commit file changes

    $ git commit -m "提交信息"
    Copy after login
    Copy after login
  • View submission records

    $ git log
    Copy after login
    Copy after login
  • Create and switch to a new branch

    $ git checkout -b <branch>
    Copy after login
    Copy after login
  • Merge branch to master branch

    $ git merge <branch>
    Copy after login
    Copy after login

2.2 SVN
SVN is another common version control system that is centralized, unlike Git. Here are some basic command examples for SVN:

  • Checkout the code repository

    $ svn checkout <URL>
    Copy after login
  • Add files to version control

    $ svn add <file>
    Copy after login
  • Commit file changes

    $ svn commit -m "提交信息"
    Copy after login
  • View commit records

    $ svn log
    Copy after login
  • Create and switch to a new branch

    $ svn copy <URL> <branch>
    Copy after login
  • Merge branches to the main branch

    $ svn merge <branch>
    Copy after login

3. Use version control to manage PHP code
During the PHP development process, we can use it in the following ways Version control system management code:
3.1 Create a new Git repository

$ git init
Copy after login
Copy after login

3.2 Add code files to version control

$ git add <file>
Copy after login
Copy after login

3.3 Submit code changes

$ git commit -m "提交信息"
Copy after login
Copy after login

3.4 View code submissions Record

$ git log
Copy after login
Copy after login

3.5 Create and switch to a new branch

$ git checkout -b <branch>
Copy after login
Copy after login

3.6 Merge the branch to the main branch

$ git merge <branch>
Copy after login
Copy after login

In the above operations, you can perform corresponding commands according to actual needs operate. These commands will help us complete the version control and management of the code.

Conclusion:
Version control and code management are very important for the development of PHP projects. Through version control, we can better manage and track code changes, and facilitate collaborative development. We can choose a suitable version control system, such as Git or SVN, and combine it with specific commands to manage PHP code. By learning and using version control systems, we can improve development efficiency, reduce code conflicts, and ensure code consistency and maintainability.
