PHP7.2,php7.3报错The each() function is deprecated. This message will be suppressed on..

php7.2以上 废除了 each()方法，项目中用到的地方会出现以下报错

 The each() function is deprecated. This message will be suppressed on further calls 

 解决办法。很简单:
 

while(list($key,$val)=each($array)) { 
#code
}

改成：

foreach($array as $key => $val) {
#code
}
