我已将客户的paypal电子邮件地址存储在数据库中,我想使用该电子邮件地址向他们发送资金.我正在使用PHP.

任何人请建议如何做到这一点.

解决方法:

我一直在寻找同样的问题,这里有什么对我有用.
在“沙盒”模式下测试并使用NVP(而不是SOAP).
您的服务器必须支持CURL,以验证其使用：

<?php
echo 'curl extension/module loaded/installed: ';
echo ( !extension_loaded('curl')) ? 'no' : 'yes';
echo "<br />\n";
phpinfo(INFO_MODULES); // just to be sure
?>

如果未加载或安装,请询问您的主机或get it here,否则请继续：
