php.ini on macmini

just want a safe hidden include folder

[HeadBut]

I can't find the php.ini on a new macmini!
I'd like to setup a _includesphp folder in each of my virtual domains
How do I do this. I have turned off indexes with Apache but my php can't find the files in the include folder.

thanks!

You can extend the include_path using httpd.conf

php_value include_path .:/path/to/includes

There is no php.ini file by default under OSX - various sites have instructions for creating one but I don't have any links to hand.
