【中文标题】已弃用：each() 函数已弃用。 C:\\xampp\\htdocs\\phprojekt\\library\\Zend\\Cache\\Backend.php 在第 66 行 [重复]

【英文标题】：Deprecated: The each() function is deprecated. C:\xampp\htdocs\phprojekt\library\Zend\Cache\Backend.php on line 66 [duplicate]已弃用：each() 函数已弃用。 C:\xampp\htdocs\phprojekt\library\Zend\Cache\Backend.php 在第 66 行 [重复]

【问题描述】：

我是一名大学生。

我必须安装 XAMPP，然后安装一个名为 phprojekt 的程序才能与 XAMPP 一起使用。

这是安装 PHProjekt 以便将其与 XAMPP 一起使用的过程的快速视频。

https://www.youtube.com/watch?v=bfnGns5WiAY

当我到达必须登录 PHProjekt 的部分时，我无法进入并收到一条消息：

“不推荐使用：不推荐使用 each() 函数。此消息将在 C:\xampp\htdocs\phprojekt\library\Zend\Cache\Backend.php 中的第 66 行进一步调用时被抑制”

第 66 行的代码说：“ while (list($name, $value) = each($options)) "

它在这样的函数中：

public function __construct(array $options = array())
    
        while (list($name, $value) = each($options)) 
            $this->setOption($name, $value);
        
    

注意：我是新学生，学php不是那门课的重点，也没有学过php，所以不知道怎么解决这个问题。

【问题讨论】：

PHProjekt 很长一段时间没有被触及，似乎已经被放弃了。它期待的 PHP 版本比您安装的要旧得多，并且抱怨最近已弃用的旧 PHP 功能。如果您解决了这一问题，您可能会遇到其他问题。您最好的选择可能是使用旧版本的 PHP。

是的，它有不止一个错误，但是，在使用 Barmar 在不同地方给我的解决方案后，在同一个文档和其他地方的不同地方，它是同一种已弃用的功能，我能够进入。也非常感谢你。我确实看到它有很多错误，但最后我能够输入纠正似乎避免我这样做的地方。

【参考方案1】：

使用foreach 循环：

foreach ($options as $name => $value) 
    ...

【讨论】：

非常感谢，效果很好。我会赞成你的回答，但我是新来的，所以我没有足够的声誉。
