This is a aimple setup for PHP server to automatically pull down your git repo.
The below scripts can be used a templates for you to get this setup on your own. At a minimum, you will want to change the variables in the scripts to reflect your environment.
You need to configure your git web hook to send a POST request to this PHP script whenever you push changes to a desired branch. All popular git service providors provide this functionality.
All this script does is verify that there is a POST request and then simply create a file.
The next step is to setup a cron job that runs the below shell script.
This shell script check for the existence of a deploy hook file. If one is found, then it will go into
your websites git repo. It will then perform a git reset and git pull on your repo. The latest updates
will then get pulled down to your server.
Ensure that permissions are set to 700.
I schedule this job to run every 5 mins via a cron job.

When you setup git on your server, you will want to make sure that you setup deployment ssh keys with your remote git service. This will make sure that everything is more secure. Check with your git service (Bitbucket, GitHub, etc) on how to set these up.
