1. Set the php.ini setting xdebug.profiler_enable_trigger to 1
2. Use either a cookie, get or post variable with the name
   "XDEBUG_PROFILE" and a random value. Then for that request there will
   be a profile file generated.

This is in the docs
at: http://xdebug.org/docs/profiler#profiler_enable_trigger
