I upgraded to 5.1.6 and code that used to be able connect to versign stopped working, specifically pfpro_init calls are no longer recognized. The manual states that since 5.1 these functions are no longer apart of PHP and that you should get them from PECL.
The PECL website does not seem to have any PayFlow Pro modules available for download and there isnt any reasonable documentation on what someone who wants to use PayFlow pro should do to get it working.
Any help would be greatly appreciated.
