How to trigger XDebug profiler for a command line PHP script?

XDebug offers the configuration directive xdebug.profiler_enable_trigger that allows to activate profiling by passing the GET or POST parameter “XDEBUG_PROFILE” when calling a script via HTTP. This is handy if you don’t want profiling for ALL of your scripts but only for a few special cases without always changing your PHP configuration.

Is there a way to achieve the same behavior for command line PHP programs? I tried to pass the XDEBUG_PROFILE as a command line argument but it didn’t work.

In general, profiling command line PHP works well, but I’d like to have the same per-call-flexibility as with a browser and HTTP server.


You can pass INI settings with the -d flag: php -d xdebug.profiler_enable=On script.php.
