I am completely new on PHP and Xdebug. I have installed XAMPP on Windows 10 and I have a running application on PHP.
So I wanted to trace the application on Visual Studio Code to understand it, I used the Xdebug. I did the following:
I download the appropriate php-xdebug.dll (according to PHP version, on xdebug.org/wizard) and place it on PHP directory of XAMPP.
I installed the PHP debug extension and added these lines:
xdebug.mode = debug
xdebug.start_with_request = yes
xdebug.client_port = 9000
Add this line to json:
"runtimeExecutable": "C:\\Xampp\\PHP\\php.exe"
Restart the Apache service in XAMPP.
Now I started the application and put some breakpoint to trace the application. It worked fine for about 4 or 5 hours, without any problem. But after that it stop working.
When I put the breakpoint it enters the breakpoint. When I press "press into" button, nothing happens and it seems Xdebug not working.
How can I check what is the problem with Wdebug?
EDIT:
This is what I found. This is a very simple code which I want to trace:
<?php
$a=100;
$b=200;
echo $a."<br/>";
echo $b."<br/>";
echo $a+$b;
If I place in the root of htdocs, the Xdebug won't work any more, but if I put in a subdirectory inside htdocs then the debug works fine.
This the result in Xdebug log file:

The only I could do , I changed the website Folder from htdocs to htdocs/Projects. and everything worked fine after that. I couldn't find the reason
