知识付费使用PHP7.2以上版本时h5支付宝支付报错
系统错误
The each() function is deprecated. This message will be suppressed on further calls

原因：PHP7.2废除了each()函数

解决：找到AopClient.php文件 buildRequestForm方法中 each修改为forcach

foreach($para_temp as $key=>$val){
     if (false === $this->checkEmpty($val)) {
         //$val = $this->characet($val, $this->postCharset);
          $val = str_replace("'","'",$val);
          //$val = str_replace("\"",""",$val);
           $sHtml.= "<input type='hidden' name='".$key."' value='".$val."'/>";
      }
 }

下图为需要修改的位置
