NYCPHP Meetup

[Joel De Gan]

I wrote a tutorial on this for zend.com:
here: http://www.zend.com/zend/tut/tutorial-paypal.php
or plaintext: http://www.zend.com/zend/tut/tutorial-paypal.php?print=1

Or for "sending" money through paypal.. here:
http://lucifer.intercosmos.net/?view=SNIP&item=52

I also did http://ipn.joihost.com which is an IPN logger/reposter and is
listed on the official Paypal website under IPN logging services. It
really does not do a lot of traffic right now, so if you needed pieces
let me know.

Cheers
