This extension allows you to process credit cards and other financial
     transactions using Verisign Payment Services, formerly known as Signio
     (http://www.verisign.com/products-services/payment-processing/online-payment/payflow-pro/index.html).
    
     When using these functions, you may omit calls to
     pfpro_init() and pfpro_cleanup()
     as this extension will do so automatically if required. However the
     functions are still available in case you are processing a number of
     transactions and require fine control over the library.
     You may perform any number
     of transactions using pfpro_process() between the two.
    
     These functions were added in PHP 4.0.2.
    
Note: 
      These functions only provide a link to Verisign Payment Services. Be sure
      to read the Payflow Pro Developers Guide for full details of the required
      parameters.
     
Note: 
      This extension has been moved to the PECL repository and is no longer bundled with 
PHP as of PHP 5.1.0.
     
Note: This extension is not
available on Windows platforms.
     You will require the appropriate SDK for your platform, which may be
     downloaded from within the manager
     interface once you have registered. 
    
     Once you have downloaded the SDK you should copy the files from
     the lib directory of the
     distribution. Copy the header file pfpro.h
     to /usr/local/include
     and the library file libpfpro.so to
     /usr/local/lib.
    
     Alternatively, you can extract the tarball from Verisign in one
     location, and reference it during build configuration with the --with-pfpro[=DIR] option:
     
| Example 1. Explicit Configuration | tar -zxf pfpro_sunsparc.tar.gz -C /usr/local/
./configure --with-pfpro=/usr/local/verisign/payflowpro/sunsparc | 
 | 
    Note: 
      The last portion of the path specified in the example above, in this
      case sunsparc, will vary based on
      which architecture your Verisign SDK was built for.
     
  These functions are only available if PHP has been compiled with the
  --with-pfpro[=DIR] option.
 
| Warning | 
| 
   If you are planing to use this extension along with the OpenSSL extension or with ModSSL, you should
   compile this extension as shared: --with-pfpro=shared,/usr/local.
   | 
The behaviour of these functions is affected by settings in php.ini.
