PHP Git Repo

Manage a Git repository with PHP. Provide an object oriented wrapper to run any Git command.

Requirements

• PHP >= 5.2 (PHP 5.3 works fine)
• Git >= 1.5

Instantiate a PHPGit_Repository

$repo = new PHPGit_Repository('/path/to/the/git/repo');

It does NOT create a Git repo, but a PHP object to manipulate an existing Git repo.

Create a Git repository

If the Git repository does not exist yet on filesystem, PHPGit_Repository can create it for you.

$repo = PHPGit_Repository::create('/path/to/the/git/repo');

It runs git init and returns a PHPGit_Repository object.

Run git commands

git commands can be run with the same syntax as in the CLI. Some examples:

// change current branch to master
$repo->git('checkout master');

// pull from a remote
$repo->git('pull origin master');

// add a remote repo
$repo->git('remote add origin git://github.com/ornicar/php-git-repo.git');

There is no limitation, you can run any git command.

The git() method returns the output string:

echo $repo->git('log --oneline');

c14c9ec Initial commit

The git() method throws a GitRuntimeException if the command is invalid:

$repo->git('wtf'); // this git command does NOT exist: throw GitRuntimeException

Get branches informations

Some shortcut methods are provided to deal with branches in a convenient way.

Get the branches list:

$branches = $repo->getBranches();
// returns array('master', 'other_branch')

Get the current branch:

$branch = $repo->getCurrentBranch();
// returns 'master'

Know if the repo has a given branch:

$hasBranch = $repo->hasBranch('master');
// returns true

Get tags informations

Get the tags list:

$tags = $repo->getTags();
// returns array('first_release', 'v2')

Get commits informations

You can get an array of the last commits on the current branch.

$commits = $repo->getCommits(15);
// returns an array of the 15 last commits

Internally, this methods run git log with formatted output. The return value should look like:

Array
(
    [0] => Array
        (
            [id] => affb0e84a11b4180b0fa0e5d36bdac73584f0d71
            [tree] => 4b825dc642cb6eb9a060e54bf8d69288fbee4904
            [author] => Array
                (
                    [name] => ornicar
                    [email] => myemail@gmail.com
                )

            [authored_date] => 2010-09-22 19:17:35 +0200
            [commiter] => Array
                (
                    [name] => ornicar
                    [email] => myemail@gmail.com
                )

            [committed_date] => 2010-09-22 19:17:35 +0200
            [message] => My commit message
        )

    [1] => Array
        (
            ...

The first commit is the more recent one.

Debug mode

PHPGit_Repository constructor second parameter lets you enable debug mode. When debug mode is on, commands and their output are displayed.

$repo = new PHPGit_Repository('/path/to/the/git/repo', true);

Configure

PHPGit_Repository can be configured by passing an array of options to the constructor third parameter.

Change git executable path

You may need to provide the path to the git executable.

$repo = new PHPGit_Repository('/path/to/the/git/repo', false, array('git_executable' => '/usr/bin/git'));

On most Unix system, it's /usr/bin/git. On Windows, it may be C:\Program Files\Git\bin.

Change the command class

By default, PHPGit_Repository will use PHPGit_Command class to implement Git commands. By replacing this option, you can use your own command implementation:

$repo = new PHPGit_Repository('/path/to/the/git/repo', false, array('command_class' => 'myGitCommand'));

Run test suite

All code is fully unit tested. To run tests on your server, from a CLI, run

php /path/to/php-git-repo/prove.php
