这两天集中时间开发了she’s的php版本的支付宝接口，支付宝的官方网站只提供了
jsp和asp版本的接口的示例代码，竟然不提供PHP版本接口代码，
我粗略的看了下jsp版本的代码，
估计是和我找到的php代码一样（在支付宝论坛里）都是热心网友提供的。我是J2ee程序员，根本不懂
PHP,让我按照支付宝的交易服务集成技术文档硬写一个接口出来实在有些难度，
最重要的一点是支付宝不提供这个文档以外的支持。还好有热心的网友分享他们的代码。
目前网络上面流传的PHP接口的代码主要有两个一个是basedzfbphp版本。另外一个是版本，前者只支持支付宝1.0的接口（我弄完才知道又换成后者）。
目前支付宝已经升级到2.0，所以大家可以参考
phpshiwu 这个版本或者参考我刚弄完的这个（基于PHPshiwu）
