If I create a php.ini file in the cgi-bin directory, does that replace the entire php.ini file, or does it only affect/override the specific items I change?

I want to set
date.timezone
date.default_latitude
date.default_longitude
auto_prepend_file

If you do it the right way it will only overwrite the specific strings you place in that file. I will provide a link to a help document for reference below.
