PHP Git practice: How to resolve code conflicts?

Code conflicts occur when Git detects that different developers have made changes to the same part of the same file. The steps to resolve code conflicts include: 1. Identify the conflicting files; 2. Open the conflicting files to compare and merge the changes; 3. Stage the merged changes; 4. Commit the merged changes.

PHP Git in practice: resolving code conflicts

Git is a distributed version control system that allows multiple developers to collaborate Work on the same project. However, when multiple developers edit the same file at the same time, code conflicts can occur.

What is a code conflict?

Code conflicts are what happen when two or more developers try to make changes to the same part of the same file. Git will detect conflicts when trying to merge these changes and prevent the merge.

How to resolve code conflicts

To resolve code conflicts, you need to merge conflicting files manually. To do this, follow these steps:

1. Identify conflicting files: Use the git status command to see which files have conflicts.
2. Open conflicting files: Use a text editor to open conflicting files.
3. Compare conflicts: View conflict areas. Git adds markers 444ab080e7b9bda1b93d0c59aa6f55a5>>>> around conflict areas.
4. Merge changes: Merge your desired changes into the file and remove conflict markers.
5. Staging changes: Use the git add command to stage the merged changes.
6. Commit the merge: Use the git commit -m "Resolve conflicts" command to commit the merged changes.

Practical Example

Suppose you and your colleague are working on the same PHP script. You both made changes to the same line of code. Git detects conflicts when merging requests.

To resolve this conflict, perform the following steps:

1. git status The command shows that there is a conflict in script.php.
2. Open script.php with a text editor.
3. Git adds 444ab080e7b9bda1b93d0c59aa6f55a5>>>> tags around the conflicting code:

<<<<<<< HEAD
echo "Hello from Alice";
=======
echo "Hello from Bob";
>>>>>>> master

4. You want to merge the code so you can keep the changes from both lines of code:

echo "Hello from Alice and Bob";

5. Remove the conflict markers and save the file.
6. git add script.php command stages the merged changes.
7. git commit -m "Resolve conflicts" command commits the merged changes.

After completing these steps, the code conflicts will be resolved and the merge request can be merged.

Tip

• Use the git diff command to view details of conflicting changes.
• If you are unable to resolve conflicts manually, you can use the git mergetool command to use a graphical tool to help you.
