Description

Basically, Netbeans is current unusable for developing and debugging code using PHP 8.0.

PHP v8.0 requires xdebug v3.0.1   Following the xdebug configuration instructions as follows

zend_extension = C:\Program Files\php\8.0\ext\php_xdebug-3.0.1-8.0-vs16-nts-x86_64.dll
xdebug.mode=debug
xdebug.remote_enable=on
xdebug.remote_host=localhost

I am finding that I receive a large number of xdebug timeout errors linked to the connection between the IDE and webbrowser.

It appears to be a state problem as the debugger session runs OK, but if you attempt to stop the debugging session from the Netbeans IDE, the communication between browser is stopped. The only workaround I have found is to reset the Netbeans workspace IDE.

As per the xdebug 3.0.1 installation instructions, I have change the debug port within the Netbeans IDE environment to use port 9003.
