[GENERAL] PHP and Postgresql on Windows

[typing80wpm]

What would I need to do to make PHP, installed on my desktop, talk to Postgresql.  I have several CDS with WAMP installs (Windows Apache Mysgl PHP).   Would I use some special driver to allow PHP to connect to Postgresql?  I am going to search on google as soon as I post, but just curious if someone has a word of wisdom. Thanks
