I am aware that wp-config.php stores the core config settings of wordpress. What all other PHP files are used to store such config/settings of core wordpress? What all PHP files are used to store such settings of wordpress plugins? Or can I assume that other than wp-config.php– all other settings are stored in database itself?
Also, when a user creates a new page/blog post/etc in his site (under WPMU installation) then is the core content stored in database? Or is some/all of it stored in php files?
I specifically want to know of scenarios where php files are used to store any information – viz user blog post, user page creation, wordpress settings, plugin information ….
I hope you can clearly answer my question for all of the scenarios I have mentioned in the previous sentence.
