FS#844 php.ini explanation
Maybe a page about the php.ini entries relevant to DokuWiki would be a good idea.
What I have in mind is a standalone page that discusses the important configuration options and suggests reasonable values - something like the wiki:config page that will cover only the important options.
I believe this would be valuable for people new to PHP applications.
If you think such a page would be useful go ahead and create it in the wiki.
