Debug script without XDEBUG_SESSION_START parameter

Question

I am debugging a web service in PHP and there is no facility for adding the XDEBUG_SESSION_START to the single buggy remote server that has issues that don't happen in my test servers. I do know ahead of time before the server in question makes its GET request to the web service. Is there any way to have Xdebug run for the next request, even if the XDEBUG_SESSION_START parameter is not sent?

Answer 1

The solution is to add xdebug.remote_autostart=1 to /etc/php5/conf.d/20-xdebug.ini and restart Apache with sudo service apache2 restart.
