PHP 7.2 each()函数已弃用 [英] php 7.2 each() function is deprecated

问题描述

       if ( is_array( $u ) ) {
            while( list( $key ) = each( $u ) ) {
                $u = $u[$key];
                break;
            }
        }

并且我的php版本是7.2 当我在laravel框架上运行它时，我遇到了这个错误

and my php version is 7.2 when i run it on laravel framwork i gat this error

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

我发现多数民众赞成我必须将每个更改为foreach 在此处输入链接描述

告诉任何人将代码更改给我，以便在php 7.2上工作

推荐答案

        while( list( $key ) = each( $u ) ) {
            $u = $u[$key];
            break;
        }

绝对没有理由在这里进行循环.您只是从数组中获取第一个值并覆盖该数组.可以使用current()在一行中重写上述循环，这会将当前值(如果未更改数组的指针，则为第一个值)从数组中拉出:

There's absolutely no reason to do a loop here. You're just getting the first value out of the array and overwriting the array. The above loop can be rewritten in one line using current() which will pull the current value (first value if the array's pointer hasn't been altered) out of the array:

$u = current($u);
