最近都在使用 Git@OSC 代码托管，分享一个php写的获取git仓库信息的类

这个类可以获取信息的一个Git仓库。

它使用的Git客户端程序查询库来获得某些类型的统计信息。

目前，它可以得到所有提交给定的分支，得到的最新提交的哈希，一个给定的分支的数量提交并获得一个给定的分支版本。

测试类

<?php
require_once("git.class.php");
$repo_path = "/home/git/repositories/";
$git = new git;
$repos = $git->get_repos("/home/git/projects.list");
if(isset($_GET['git']) && in_array($_GET['git'], $repos) && file_exists($repo_path.$_GET['git']."/refs/heads/master")) {
    if(isset($_GET['header']) && !empty($_GET['header']) && file_exists($repo_path.$_GET['git']."/refs/heads/".$_GET['header'])) {
        $header=$_GET['header'];
    } else {
        $header="master";
    }
    echo $git->get_version($repo_path.$_GET['git'], $header);
} else {
    echo "404 Not Found - No such project";
}
