In software development, version management is an extremely important link. Because writing code in a team inevitably requires merging everyone's code. Version management tools can help us track code changes and avoid conflicts when merging. Among them, Git is currently the most popular version management tool, a must-have for both personal development and team collaboration.
This article will focus on Git to introduce you to the benefits of using version management tools, the basic concepts and basic operations of Git, and explain how to use Git to collaborate with the team for development.
In software development, version management is a very important link. Developing a software requires constantly modifying the code and adding new functions. Version management tools can help developers:
With version management tools, we can easily track code modifications and view each developer's contribution record, and at the same time, we will not cause the entire project to go wrong because of some small mistakes.
When using Git, there are some basic concepts that you need to understand first:
The warehouse is used to store code Place, similar to a folder. Each warehouse can contain one project or multiple projects. It stores all versions of the code, along with details about each version.
Submission refers to saving changes to the code repository. When submitting, a description of the modifications needs to be recorded.
A branch can be imagined as a new version based on existing code. Branches can be used to develop new features and fix existing problems in the code. Modifications made to a branch will not affect other branches and code on the main line.
Merge refers to bringing together the modifications of two or more branches. This process can help us complete the collaborative development of different branches.
Remote repository refers to the place where the code is hosted (for example: Github). It can be synchronized with local repositories to ensure the effectiveness of team collaboration and development.
Next, we will introduce some basic operations of Git:
Use Git to create a new code warehouse, you can Use the following command:
git init
This command will create a new Git code repository under the current path.
To add files to the git repository, you can use the following command:
git add filename
This command will add the modified files to the cache area, but will not Not committed to the repository.
After adding files to the Git warehouse cache, if we want to submit these files to the warehouse, we can use the following command:
git commit -m "commit message"
This command will The files in the cache area are submitted to the current branch, and the description information of this submission is recorded.
To create a branch and switch to a new branch, you can use the following command:
git checkout -b branchname
-b parameter is used to specify to create a new branch and switch to a new branch on the branch. If you do not add the -b parameter, you will just switch to the existing branch.
To merge a branch into the current branch, you can use the following command:
git merge branchname
This command will merge the changes of the specified branch into the current branch. on the branch. If there are code conflicts between branches, Git will prompt you to resolve the conflicts before merging.
To synchronize the local warehouse with the remote warehouse, you can use the following command:
git push
This command will push the local warehouse to the remote warehouse. If you want to download the code of the remote warehouse, you can use the following command:
git pull
This command will download the new changes from the remote warehouse and then automatically merge them with the local warehouse.
Git can help teams collaborate on development and avoid code conflicts. The following are some common operations for team collaboration development in Git:
Using Git for code management can facilitate us to track code modifications, work together, and improve the reliability of the code. In the team, using Git can help us better complete team collaboration and development. For PHP developers, Git is one of the essential skills.
