# CL. Verisign Payflow Pro Functions

# 简介

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.

> 注: 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.

> 注: 本扩展已被移动到 PECL 库中且自以下版本起不再被绑定到 PHP 中：5.1.0.

> 注: 本扩展模块在 Windows 平台下不可用。

# 需求

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:

例子 1. Explicit Configuration

    tar -zxf pfpro_sunsparc.tar.gz -C /usr/local/

    ./configure --with-pfpro=/usr/local/verisign/payflowpro/sunsparc

> 注: 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.

# 安装

These functions are only available if PHP has been compiled with the --with-pfpro[=DIR] option.

警告
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.

# 运行时配置

这些函数的行为受 `php.ini` 的影响。
