从 PHP 中的数组键创建新变量 [英] Create new variables from array keys in PHP

问题描述

假设我有一个数组，如下所示:

Suppose I have an array, like this:

$foo = array('first' =>  '1st',
             'second' => '2nd',
             'third' =>  '3rd');

如何从数组中挑选键并使它们成为自己的变量?例如，数组 $foo 将变成:

How can I pick the keys out of the array and make them their own variables? For example, the array $foo would become:

$first = '1st';
$second = '2nd';
$third = '3rd';

我问这个是因为我正在创建一个 MVC 框架来帮助我的 OOP，我希望用户将一个变量传递给视图加载函数，这将允许用户在模板中使用变量而无需知道这个数组叫什么.

I ask this because I am creating an MVC framework to help with my OOP, and I would like the user to pass a variable to the View loading function, which will allow the user to use variables in the template without having to know what the array was called.

例如:

$array = array('title' =>  'My blog!' [...]);
$this->load->view('view.php', $array);

view.php:

echo $title;

输出:

我的博客！
