Question

我基本上使用此配置为Symfony项目https://github.com/maxpou/docker-symfony创建开发环境。它运行但我不能让Xdebug工作：当我设置一个断点时它不会停止。

我还尝试配置Xdebug以使用connect_back，但这不起作用。也许这与我在Windows机器上开发的事实有关？任何见解都非常感激。

Answer 1

Xdebug的流量并没有找到它回到我的主机的方式。当我在xdebug.remote_host中输入主机的IP地址时，调试工作正常，但这并不理想，因为我的IP在每次重启时都会更改。幸运的是，Docker提供了一种通过docker.for.win.localhost获取主机IP的方法。

我尝试使用xdebug.remote_connect_back = 1，它只响应来自它的流量，但它没有工作。 Phpinfo（）显示REMOTE_ADDR设置为localhost。使用此设置需要知道的是.ini中的xdebug.remote_host将被忽略。

来自Xdebug文档：

xdebug.remote_connect_back   类型：布尔值，默认值：0，在Xdebug中引入＆gt; = 2.1

如果启用，则忽略xdebug.remote_host设置，Xdebug将尝试连接到发出HTTP请求的客户端。

这是Dockerfile，其中包含适用于PHP Docker容器的xdebug.ini配置：

添加remote_connect_back =，因此xdebug连接到当前访问者（使用REMOTE_ADDR系统变量）而不是可能更改的remote_host。您也可以尝试使用remote_autostart = on，以确保此问题与浏览器本身无关。

请记住在phpStorm中配置映射，但无论如何它都会告诉你这样做。还要确保IDE正在侦听调试会话（调试工具栏中的小切换）。祝你好运。
