Display the current Git 'version' in PHP
提问by lukeocodes
I want to display the Git version on my site.
我想在我的网站上显示 Git 版本。
How can I display a semantic version number from Git, that non-technical users of a site can easily reference when raising issues?
如何显示来自 Git 的语义版本号，网站的非技术用户在提出问题时可以轻松参考？

Firstly, some gitcommands to fetch version information:
首先是一些git获取版本信息的命令：
- commit hash long
git log --pretty="%H" -n1 HEAD
- commit hash short
git log --pretty="%h" -n1 HEAD
- commit date
git log --pretty="%ci" -n1 HEAD
- tag
git describe --tags --abbrev=0
- tag long with hash
git describe --tags
- 提交哈希长
git log --pretty="%H" -n1 HEAD
- 提交哈希短
git log --pretty="%h" -n1 HEAD
- 提交日期
git log --pretty="%ci" -n1 HEAD
- 标签
git describe --tags --abbrev=0
- 用哈希标记 long
git describe --tags
Secondly, use exec()combined with the git commands of your choice from above to build the version identifier:
其次，exec()结合您从上面选择的 git 命令来构建版本标识符：
class ApplicationVersion
{
const MAJOR = 1;
const MINOR = 2;
const PATCH = 3;
public static function get()
{
$commitHash = trim(exec('git log --pretty="%h" -n1 HEAD'));
$commitDate = new \DateTime(trim(exec('git log -n1 --pretty=%ci HEAD')));
$commitDate->setTimezone(new \DateTimeZone('UTC'));
return sprintf('v%s.%s.%s-dev.%s (%s)', self::MAJOR, self::MINOR, self::PATCH, $commitHash, $commitDate->format('Y-m-d H:i:s'));
}
}
// Usage: echo 'MyApplication ' . ApplicationVersion::get();
// MyApplication v1.2.3-dev.b576fd7 (2016-11-02 14:11:22)

要点：https: //gist.github.com/lukeoliff/5501074
<?php
class QuickGit {
public static function version() {
exec('git describe --always',$version_mini_hash);
exec('git rev-list HEAD | wc -l',$version_number);
exec('git log -1',$line);
$version['short'] = "v1.".trim($version_number[0]).".".$version_mini_hash[0];
$version['full'] = "v1.".trim($version_number[0]).".$version_mini_hash[0] (".str_replace('commit ','',$line[0]).")";
return $version;
}
}

If you'd like to do it without exec()and you're using git lightweight (see comments below) tagging:
如果您不想这样做exec()并且您正在使用 git 轻量级（请参阅下面的评论）标记：
You can get the current HEAD commit hash from .git/HEADor .git/refs/heads/master. We then loop to find matching. Reversing the array first for speed because you're more likely to at a higher recent tag.
您可以从.git/HEAD或获取当前的 HEAD 提交哈希.git/refs/heads/master。然后我们循环查找匹配项。首先反转数组以提高速度，因为您更有可能使用更高的最近标签。
So if the current php file sits in a public_htmlor wwwfolder one level down from the .gitfolder...
因此，如果当前的 php 文件位于文件夹下一级的public_html或www文件.git夹中...
<?php
$HEAD_hash = file_get_contents('../.git/refs/heads/master'); // or branch x
$files = glob('../.git/refs/tags/*');
foreach(array_reverse($files) as $file) {
$contents = file_get_contents($file);
if($HEAD_hash === $contents)
{
print 'Current tag is ' . basename($file);
exit;
}
}
print 'No matching tag';

Simple way:
简单的方法：
- Short hash:
$rev = exec('git rev-parse --short HEAD'); - Full hash:
$rev = exec('git rev-parse HEAD');
- 短哈希：
$rev = exec('git rev-parse --short HEAD'); - 完整哈希：
$rev = exec('git rev-parse HEAD');

I did it just as:
我是这样做的：
substr(file_get_contents(GIT_DIR.'/refs/heads/master'),0,7)
substr(file_get_contents(GIT_DIR.'/refs/heads/master'),0,7)
resource friendly and the same as i have under eclipse shown
资源友好，与我在 eclipse 下显示的相同
