I used below code : 

    echo exec("git add . ");  //this is working  
echo exec("git commit -am 'first commit' "); //also working  
echo exec("git push origin master");  //NOT WORKING, also not showing any error .

I chowned folder permissions from user to www-data . So, some git commands are working but 

GIT PUSH ORIGIN MASTER

is not working from php exec . What is the solution ? Also, please tell me why PUSH in exec NOT showing any error or msg, how can i see those msgs . Also,if possible, please provide me any good links for more advanced use of git commands from php exec .

Update : I also tried this : I added post-commit hook by creating file .git/hooks/post-commit

I added this code to it :

git push origin master

But I didnt get any msg or error after commiting, it just commited but didnt do any push.

Thanks !

  • Did you try git push origin master normally via terminal? What was the result? BTW, which directory is it getting executed? Commented Jun 28, 2012 at 6:48
  • It doesn't answer your question, but have you looked at PHP bindings for libgit2? Commented Jun 28, 2012 at 7:13
  • No I didnt check PHP bindings . And Mr. Praveen , it is getting executed at /var/www/fd/index.php . I tried it using terminal and got permission denied (public key) error when using sudo . And without using sudo, it pushed but failed writing resullt to git as sudo is required to write data in that folder(as i chowned as www-data) Commented Jun 28, 2012 at 7:34

I assume the push command will try to push to a remote repository (i.e. not another folder on your system but a remote server behind SSH/HTTPS).

In this case you are most likely missing a HTTPS client certificate HTTPS or an SSH key. Your webserver (and therefore PHP) most likely runs as a different user and does not have access to the private key. Next to that if the private key needs a password it will not work because the exec command is not an interactive session.

Anyway I heavily recommend you to use some sort of bindings and not calling the binaries. Any direct call will start a new process and this is way more inefficient that calls into a library.

This is a good answer. It answered the commit and push. One needs the permission of the web server (apache) which on linux is 'www-data'. There will be a .ssh directory created in /var/www and it needs your id_rsa (or other keys) as read/write to www-data. Also the .git directory and its contents to be read/write to group www-data. Permissions can be a real conundrum.

Have you checked which branch your are on? 'git status' will tell you.

I'd also recommend working on a branch and not directly on master.

git branch dev_test

git checkout dev_test

git add .

git commit -a -m "first comment"

git push origin dev_test

git checkout master

git merge dev_test

git push origin master
