I installed PHP 4.2.2 on a Mac running OS X 10.1.5 and the Apache server from Marc Liyanage's site:
http://www.entropy.ch/software/macosx/php/
It doesn't come with a php.ini file - he says I can just make one, which I did, but it doesn't have any settings except "register_globals", which I set up. Is there somewhere I can get a "standard" (default) php.ini file so I can see the syntax and all the other things that are turned on or off?
