HomeBackend DevelopmentPHP Tutorial使用PHP建立SVN的远程钩子,使用exec命令自动更新SVN的代码

本操作需要使用到php执行sudo命令的权限,相关设置可以参考:
apache/Nginx下的PHP/Ruby执行sudo权限的系统命令

通过Svn的钩子功能,可以在我们执行SVN操作时,同时自动执行一些操作,比较常见的操作有:
1,本地更新并提交代码时,在测试环境或者线上环境同时将代码更新到最新版
2,在更新Svn时,如果有数据库相关的操作,可以同时将SQL发给远程钩子程序执行相关的SQL

这个实例是我们项目组用到的一个片段,实现在本地开发代码测试通过以后,往线上提交SVN时,自动将代码更新到线上,或者执行导出打包的工作

<?php//先切换到程序部署的目录$path = dirname(__FILE__);exec("cd {$path}"); exec("sudo /usr/bin/svn up", $output);print_r($output);

这里需要将apache加入sudoer组

为此,修改sudo配置文件,直接键如visudo命令编辑配置文件:

1. 注释Defaults requiretty
Defaults requiretty修改为 #Defaults requiretty, 表示不需要控制终端。
否则会出现sudo: sorry, you must have a tty to run sudo

2. 增加行 Defaults visiblepw
否则会出现 sudo: no tty present and no askpass program specified

3. 赋予apache用户执行svn权限
如,增加行:apache ALL=(ALL) NOPASSWD: /usr/bin/svn
注:NOPASSWD可以使在命令执行时不需要交互输入apache用户的密码

最后一步,即在SVN钩子中添加提交SVN时,自动访问远程链接“http://www.4wei.cn/yoursvnfile.php”

Dependency Injection in PHP: Code Examples for BeginnersDependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
