There comes a time when debugging that you hit a brick wall. All the logs indicate that my PHP.XDEBUG setup (client running VSCODE and Windows Server with PHP/XDEBUG) should be working but it is triggering a "Fatal error" in the log file that is not helping me to interrupt the problem - There appear to be extraneous breakpoints being identified but I have cleared everything, so the question is can anybody please help: In summary:
- XDEBUG has produced a log file
- It has connected to the client machine
- It has identified the localhost project path
c:/Development-DEV/VSCode/Prog/phpinfo.php -n 3 - It has identified the breakpoint (line 3)
Here is the project and launch.json being debugged and deployed to the server:
1 <?php
2
3 echo "Hello"; <- breakpoint
4 echo "world";
5
6 ?>
Launch.json file
{
"name": "Listen for XDebug",
"type": "php",
"request": "launch",
"port": 9003,
"log": true,
}
Here is the PHP.INI file [XDEBUG} settings from the Windows Server:
[XDebug]
;zend_extension = "C:\php\ext\php_xdebug-2.7.0RC1-7.3-vc15-nts-x86_64.dll"
zend_extension = "C:\php-7.4.30-nts-Win32-vc15-x64\ext\php_xdebug-3.1.5-7.4-vc15-nts-x86_64.dll"
;zend_extension = "php_xdebug.dll"
xdebug.remote_enable = 1
xdebug.remote_autostart = 1
xdebug.client_port=9003
xdebug.remote_handler=dbgp
xdebug.remote_connect_back = 0
xdebug.mode = debug
xdebug.start_with_request = yes
xdebug.client_host=localhost
xdebug.discover_client_host=true
xdebug.idekey=VSCODE
xdebug.output_dir="C:\InetPub\wwwroot\logs\"
xdebug.log = 'C:\InetPub\wwwroot\logs\xdebug.log'
Here is the XDEBUG log taken from the server.

The log file has the following lines:
<init … fileuri="file:///C:/inetpub/wwwroot/phpinfo.php" …
VS Code and its plugin set this breakpoint:
breakpoint_set -i 3 -t line -f file:///c:/Development-DEV/VSCode/Prog/phpinfo.php
The paths in these don't match, which usually hints that you need to set-up path mappings. Xdebug can only see the file location on the system where PHP *runs, whereas the IDE (VS Code) uses the path it sees on the file system where your development files are.
I do not know how you synchronise these yourself though.
You can make path mappings in your launch.json file, as follows:
{
"name": "Listen for XDebug",
"type": "php",
"request": "launch",
"port": 9003,
"log": true,
"pathMappings": [
"file:///C:/inetpub/wwwroot" : "file:///c:/Development-DEV/VSCode/Prog"
]
}
I have made a YouTube video which explains this in more detail as well, starting at 3:48: https://youtu.be/ZIGdBSD6zvU?t=229.
You probably also want to remove these settings:
xdebug.remote_enable = 1 // old Xdebug 2 setting
xdebug.remote_autostart = 1 // old Xdebug 2 setting
xdebug.remote_handler=dbgp // old Xdebug 2 setting
xdebug.remote_connect_back = 0 // old Xdebug 2 setting
xdebug.discover_client_host=true // your log indicates that this fails, and that it falls back

Xdebug 2 uses port 9000 Xdebug 3 uses port 9003 https://xdebug.org/docs/upgrade_guide
