[Phpmyadmin-devel] NULL in config.inc.php

Hi, I'm working through fixing up a bit of SSL code and have encountered a difficulty. The PHP manual[1] says that unused parameters "may be given as NULL". In my testing, setting them = ''; works fine, but of course we want to do what PHP expects. In config.inc.php, we don't have any values that default to NULL, and I think it may confuse users in this case. I'd much prefer to leave them set = ''; in config.inc.php for consistency and to make it easy for users to plug in their own values. What I am thinking of is in libraries/config.default.php to set the parameters to NULL, then if the user decides to overwrite it in config.inc.php there is no problem. In that case, I'm not sure I'd write the end-user documentation as if the default was = ''; or NULL. If my question has made sense, what do you think? 1 - http://php.net/manual/en/mysqli.ssl-set.php
