的foreach和2D的PHP数组 [英] Foreach and 2D Array in PHP

问题描述

$mainMenu['Home'][1] = '/mult/index.php';
$mainMenu['Map'][1] = '/mult/kar.php';
$mainMenu['MapA'][2] = '/mult/kara.php';
$mainMenu['MapB'][2] = '/mult/karb.php';
$mainMenu['Contact'][1] = '/mult/sni.php';
$mainMenu['Bla'][1] = '/mult/vid.php';

这是一个菜单中，1表示的主要部分，2表示子菜单。像：

This is a menu, 1 indicates the main part, 2 indicates the sub-menu. Like:

首页
地图
-MapA
-MapB
Contat
布拉

Home
Map
-MapA
-MapB
Contat
Bla

我知道如何使用的foreach 但据我看到它采用的是一维数组。我必须做在上面的例子？

I know how to use foreach but as far as I see it is used in 1 dimensional arrays. What I have to do in the example above?

推荐答案

您需要嵌套两个的foreach 但是，有任何关于你的数据结构，可以轻松地表示什么是一个子项。地图与地图？我想一个人能明白这一点，但你必须写很多boilerlate的脚本进行排序的..考虑转型的数据，使其更接近你想要达到的目的。

You would need to nest two foreach BUT, there is nothing about your data structure that easily indicates what is a sub-item. Map vs. MapA? I guess a human could figure that out, but you'll have to write a lot of boilerlate for your script to sort that.. Consider restructuring your data so that it more closely matches what you are trying to achieve.

下面是一个例子。你也许可以想出一个更好的系统，但：

Here's an example. You can probably come up with a better system, though:

$mainMenu = array(
    'Home' => '/mult/index.php',
    'Map' => array(
        '/mult/kar.php',
        array(
            'MapA' => '/mult/kara.php',
            'MapB' => '/mult/karb.php'
        )
     ),
     'Contact' => '/mult/sni.php',
     ...
);
