在Visual Studio代码中进行PHP调试仅适用于有时

Question

我在Visual Studio中使用xdebug进行的php调试仅在有时会起作用。有些时候，我只是得到一个正常的浏览器页面加载（错误日志下面）。

编辑： 起初我以为这是由于文件的位置，但我注意到它可能发生在任何位置;或者xdebug在代码中发现一个错误而不会停留在我自己的断点处;或者它可以找到所有类型的断点或根本找不到任何东西......现在我认为它与刷新，修改和重新保存文件以及文件中的错误类型有关。如果我能找出是什么原因，我会回头看看。

在我目前的设置中，我有我的localhost webroot在/home/user/Git/www/projects这是127.0.0.1指向的地方。但是，我还设置了多个驻留在各自子文件夹中的虚拟主机：/home/user/Git/www/projects/project_name。

有些事情我已经看了

在这个线程：Visual Studio Code - Xdebug won't work - 他们建议设置xdebug.remote_connect_back = 1，不解决问题。他们还建议在launch.json中将localSourceRoot设置为指向服务器根目录。但是，只需添加"localSourceRoot": "http://127.0.0.1"或诸如"localSourceRoot": "http://127.0.0.1/project_name"之类的东西都不起作用。

日志

/etc/hosts中

127.0.0.1 project_names 
127.0.0.1 php 
127.0.0.1 localhost 
::1   localhost 

的php.ini：

[Xdebug] 
zend_extension = xdebug.so 
xdebug.remote_enable = on 
xdebug.remote_autostart = on 
xdebug.remote_handler = dbgp 
xdebug.remote_host = 127.0.0.1 
xdebug.remote_port = 9000 
xdebug.remote_mode = req 
xdebug.idekey=php-vs 
;xdebug.remote_connect_back = 1 

launch.json：

{ 
    "version": "0.2.0", 
    "configurations": [ 
     { 
      "name": "Listen for XDebug", 
      "type": "php",

Answer 1

我终于意识到，这个问题是关系到挂载点。 VScode中的项目在网络服务器安装的路径上打开;而不是它最初指向apache的地方。所以断点被认为是添加到另一个文件，因为路径不一样。
