How can git tags be used to manage versions of a PHP project?

Git tags can be used to manage versions of a PHP project by creating a tag for each release or version of the project. This allows developers to easily identify and switch between different versions of the codebase. To create a tag, you can use the `git tag` command followed by the version number or release name. Tags can also be pushed to a remote repository using `git push --tags`.

// Example of creating a tag for a PHP project version 1.0
git tag v1.0
git push --tags
