I've just completed coding an INCLUDE file that emulates the pfpro functions:
pfpro_init();
pfpro_cleanup();
pfpro_version();
pfpro_process();
pfpro_process_raw();
Simply include this file within your script(s) and call the functions. I've posted this code under http://www.php.net/manual/en/ref.pfpro.php and submitted it to Versign for potential inclusion into their pfpro SDK.
--- CODE ---
<?php
/* { PHP_PFPRO.INC }
This file effectively acts as a fill-in or replacement for the missing PHP_PFPRO.DLL extension
for Win32 Platforms. This INCLUDE file was written and tested using PHP 4.0.6.
For instructions on how to use these functions, please go to:
http://www.php.net/manual/en/ref.pfpro.php
IMPORTANT: Before you use this INCLUDE file, you must set the following environment
variable, or this script will not work.
PFPRO_CERT_PATH = C:\Verisign\payflowpro\win32\certs <- or whatever your path is.
The following functions are present, but do nothing -- they are here for compatibility
only. I put them here so that when the PHP_PFPRO.DLL becomes available, you won't have
to change your code.
functions:
pfpro_init() : returns NULL
pfpro_cleanup() : returns NULL
pfpro_version() normally returns the version string of the PayFlowPro Library.
However, the function in this INCLUDE file returns the version of the executable.
It was frustrating indeed trying to figure out why the pfpro stuff wasn't working... I spent
a couple of days in News Groups and on the phone with Verisign... no one knows... Ahhhh... the
joy of Open Source -- I decided something had to be done (gosh darn-it) -- so I took it upon
myself to write a solution and end my frustration, and the frustration of countless others out
there fighting with the same annoying issue. A hero am I, no! -- just a geek on a mission.
In a nutshell, these functions should work nearly identical to the coming soon pfpro extension,
although, I am not totally certain, as I've never seen the official pfpro functions in action, I'm
only going by what the PHP manual says they are suppose to do... plus, I think, a little of what
I want them to do... so having said that, use this INCLUDE file at your own risk, there is no
warranty, guarantee or otherwise.
It's now 2am, and I've finished all the testing... man, I am zonked!
Enjoy,
