本文实例为大家分享了PHP支付宝即时到账功能的实现代码，供大家参考，具体内容如下
首先需要下载即时到账交易接口，传送门https://doc.open.alipay.com/doc2/detail?treeId=62&articleId=103566&docType=1
选择(create_direct_pay_by_user)
然后解压，选择MD5签名版本的文件
此文件夹里有个叫create_direct_pay_by_user-PHP-UTF-8的文件，我们就用这个文件~
接着打开文件后如图
并把文件夹lib里面的四个PHP文件重命名
alipay_core.function.php重命名为：Corefunction.php;
alipay_md5.function.php重命名为：Md5function.php;
alipay_notify.class.php重命名为：Notify.php;
alipay_submit.class.php重命名为：Submit.php;
最后在THINKPHP/Library/Vendor目录下新建文件夹命名为Alipay,把以上四个php文件复制进去如图所示
然后，打开Submit.php文件，把以下代码去掉；
require_once("alipay_core.function.php");
require_once("alipay_md5.function.php");
同样，打开Notify.php文件，把以下两段代码去掉；
require_once("alipay_core.function.php");
require_once("alipay_md5.function.php");
接下来可以写代码了（注意img文件夹里的图片地址需要修改）
HTML代码：（这个代码其实就是index里面的代码,复制如下）
