I’ve found that if you are using WinCacheGrind on Windows, the profiler output name should start with “cachegrind” instead of “callgrind” because WinCacheGrind only recognizes one type of file. Xdebug.profiler_output_dir = '/tmp/xdebug/' Xdebug.profiler_output_name = 'cachegrind.out.%t-%s' See the note below about this Xdebug.profiler_enable_trigger = On Profiling activated when requested by the GET parameter Xdebug.profiler_enable = Off Profiling not activated by default Xdebug.remote_addr_header = 'HTTP_X_XDEBUG_REMOTE_ADDRESS' See the bonus section at the very bottom for details on using this Select a connect-back IP from the $_SERVER value set in a custom header Xdebug.idekey = 'PHPSTORM' The IDE key which should match the XDEBUG_SESSION cookie value Xdebug.remote_port = 9000 Port on the IDE to connect back to. Xdebug.remote_connect_back = On Use a special $_SERVER variable to get the remote address

xdebug.remote_host = 'localhost' This is unused if the next setting is 'On' Xdebug.remote_autostart = Off Only start xdebug on demand, not on every request
