I can use PHP Tools for Visual Studio.
It works with
Project->Properties->Server->Server: IIS Express
Project->Properties->Server->URL: http://localhost:3004
But I cant use it on the debugging Port:
http://localhost:9000
Options->PHP Tools->Advanced->Xdebug Debugger Port:9000
Options->PHP Tools->Advanced->Interpreter->Debugging: xdebug.remote_port=>9000
php-ini (last section):
[XDEBUG]
xdebug.mode=debug
xdebug.client_host = 127.0.0.1
xdebug.client_port = 9000
xdebug.start_with_request=trigger
zend_extension="C:\Program Files (x86)\IIS Express\PHP\v7.4\ext\php_xdebug-3.0.1-7.4-vc15-nts.dll"
When I try, I get in the Browser an error and in Visual Studio a Lot lines with:
There was a problem initiating debugging session "Der Index war außerhalb des Arraybereichs."
