HELP!!!! Auto Deployment Laravel with Gitlab.

Hello Friends!

I need to auto pull from gitlab on my server whenever I push from my local.

• I had setup Deployment keys too..
• Integration also done. Webhooks url is also set.
• I put the pull.php file inside public folder.which looks like this :

header("Cache-Control: no-cache, max-age=0");
echo "<pre>";
shell_exec("git pull origin master");
echo "\n";
echo "========\n";
echo "\n";
echo "Last Commit\n";
echo shell_exec("git log |head -5");
echo "</pre>";

Push-events is also triggered... But its not pulling. and running Webhooks url : my-domain/pull.php show earlier commit only. not the last one

If I went through shh and run git pull origin master, it pulls. and there's fast-forward always "

remote: Enumerating objects: 15, done.
remote: Counting objects: 100% (15/15), done.
remote: Compressing objects: 100% (9/9), done.
remote: Total 9 (delta 6), reused 0 (delta 0), pack-reused 0
Unpacking objects: 100% (9/9), done.

and then if i run the Webhooks url : my-domain/pull.php it now shows the recent commits
