【中文标题】将项目从PC迁移到其他PC后，错误在codeigniter中不推荐使用each（）函数[重复]

【英文标题】：Error The each() function is deprecated in codeigniter, after migrate project from PC to other PC [duplicate]

【问题描述】：

我将一个项目从一台 PC 复制到另一台 PC。当我提交表单时，我收到一个错误。这个项目在我的第一台电脑上运行良好，但我不知道如何解决，我搜索了太多，我发现主题说问题出在 php 版本中，但我仍然不知道如何解决。另外，如果这是我的问题，这是我的错误：

【问题讨论】：

不是 CodeIgniter 弃用了 each() 函数，而是 PHP - php.net/manual/en/function.each.php - 所以降级 PHP 的版本，或者重写代码以避免使用该函数

【参考方案1】：

沉默的操作员 = 吊死自己的绳子。

-       while (list($key, $val) = each($list)) 
+       foreach ($list as $key => $val)
