Summary0001984: Can step debugging and profiling be separately triggerable?
DescriptionIs it possible (as of Xdebug 3.0 and its simplified configuration) to have a single, never-need-to-edit, never-need-to-restart-php-fpm-container xdebug.ini configuration that will support:

 - `develop` by default
 - step debugging (but not profiling) upon a trigger
 - profiling (but not step debugging) upon a _different_ trigger


If so, how?
TagsNo tags attached.
Operating System
PHP Version8.0.0-8.0.4

You can enable multiple modes at the same time by comma separating their identifiers as value to

xdebug.mode: xdebug.mode=develop,debug,profile

The triggers for debug are
in GET / POST / ENV for debug

in GET/POST/ENV for profiling

This is certainly possible.

Set xdebug.mode=develop,debug,profile

And then you can either use a browser extension as described in the documentation (, or specifically trigger
step debugging with a GET/POST/ENV/COOKIE named "XDEBUG_SESSION", or
profiling with a GET/POST/ENV/COOKIE named "XDEBUG_PROFILE"
This is all described in the documentation at

I am creating a (short) video/animation of this at the moment as well, which will show up at my YouTube channel at
