LXXXI. Verisign Payflow Pro Functions
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/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.
You will require the appropriate SDK for your platform, which may be downloaded from within the manager interface once you have registered. If you are going to use this extension in an SSL-enabled webserver or with other SSL components (such as the CURL+SSL extension) you MUST get the beta SDK.
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.
这些函数的行为受到全局配置文件 php.ini 的影响。
For further details and definition of the PHP_INI_* constants see ini_set().
