我对PHP和Xdebug完全陌生。我已经在Windows 10上安装了XAMPP，并且我有一个在PHP上运行的应用程序。
所以我想在Visual Studio代码上跟踪应用程序以了解它，我使用了Xdebug。我做了以下事情：
-
我下载了相应的php-xdebug.dll(根据php版本，在xdebug.org/wizard上(，并将其放在XAMPP的php目录中。
-
我安装了PHP调试扩展并添加了以下行：
xdebug.mode = debug xdebug.start_with_request = yes xdebug.client_port = 9000 -
将此行添加到json:
"runtimeExecutable": "C:\Xampp\PHP\php.exe" -
在XAMPP中重新启动Apache服务。
现在我启动了应用程序，并放置了一些断点来跟踪应用程序。它工作了大约4或5个小时，没有任何问题。但在那之后它就停止工作了。
当我放置断点时，它就进入了断点。当我按下"；压入"；按钮，什么也没发生，Xdebug似乎不工作。
如何检查Wdebug的问题？
编辑：
这就是我的发现。这是一个非常简单的代码，我想跟踪：
<?php
$a=100;
$b=200;
echo $a."<br/>";
echo $b."<br/>";
echo $a+$b;
如果我把Xdebug放在htdocs的根目录中，Xdebug就不能再工作了，但如果我把它放在htdocs的子目录中，那么调试就可以正常工作。
这是Xdebug日志文件中的结果：

您可以通过使用php.ini设置xdebug.log=c:tempxdebug.log创建日志来检查Xdebug的功能——如果web服务器或php无法写入，则可能需要更改路径。该日志将列出所有调试连接尝试，列出潜在的连接问题，如果建立了连接，还将列出通信。您可以检查<init标记的fileuriXML属性是否与IDE应该发送的breakpoint_set命令设置的内容相匹配。
我唯一能做的就是将网站文件夹从htdocs更改为htdocs/Projects。之后一切都很顺利。我找不到的原因
