在项目内包含git commit信息

Question

I am working on php project. Is it possible to integrate git into the project to have the info from last commit in the footer ?

I am not using build framework

Answer 1

I'd use so called git hook to achieve this. Hooks are literally scripts that execute automatically on specific git actions. The one that you might be interested in is called git post commit hook , which is a script that is automatically executed after every commit. Here's how to add one:

1. Create a script .git/hooks/post-commit :

    #!/bin/sh git log -1 --format=%cd --date=local > version.txt 

2. Make it executable:

     chmod +x .git/hooks/post-commit 

That's it. Now after every commit your version.txt will be updated with info from your last commit.

There's multiple options for doing that, but I think the best one would be to do it in during your build.

If you're using something like Jenkins, Bamboo or any other CI/CD system, you can create a task to retrieve the git commit, and save it in a readable location by the application. This could be:

• Set it as part of your configuration file
• Set it as an environment variable that you can read
• Save it in a file and read it for each request
• ...

Really, the options are endless, but it depends on the way you're building your project, and how it's being deployed. As you can see, you're not lacking options!

If you don't use a build system, maybe you should be using one then!

Still, you have the option to get the latest commit by executing something like:

echo exec('git rev-parse --short HEAD');

Which will give you the short commit hash. I'd really recommend using one of the alternative options though.

Actually after searching what I found something like that without using builds

echo exec('git log -1 --format=%cd --date=local');

That will display the time and date of last commit
