php7.2报错The each() function is deprecated. This message will be suppressed on furthe
php7.2版本将each()方法废除了，项目中使用到each()的地方会有如下报错：
Deprecated: The each() function is deprecated. This message will be suppressed on further calls in xxx/shop/alipay/alipay_core.function.php on line 55
解决方案也简单，可对应的将 each() 替换为 foreach()，我们看个例子，如下代码是报错行：
while (list($key, $val) = each($para)) { }
修改如下：
foreach ($para as $key => $val) { }
