问题:

Well, I have MAMP installed on my Mac OS X, and I've got PostGres up and running, but am wondering how I can use it with PHP? I'm assuming that there's something I need to do where I compile PHP so that it can use both, but, I'm not sure how to do that if PHP has already been installed? Or, if there's something unique I need to do to get it work on the Mac in a MAMP environment? I'm really unfamiliar with installations ,etc., so, help / direction / links, etc., is greatly appreciated. I've been googling, but think maybe I'm not even searching for the right terms...

First of all, you should use a PHP script containing

<?php
phpinfo();

This will show you which PHP extensions are installed / enabled.

With a bit of luck, you'll have mysql/mysqli/pdo_mysql and pgsql/pdo_pgsql already installed -- which means it'll be OK from the PHP side : you'll just have to use the right functions/classes to connect to your pg and/or MySQL servers.
