循环遍历二维数组 [英] Loop through a two-dimensional array

问题描述

我有一个看起来像这样的数组:

I have an array that looks like this:

$array = array(
    array(
        "http://google.com",
        "Google"
    ),

    array(
        "http://yahoo.com",
        "Yahoo"
    )
);

遍历它的最简单方法是什么.类似的东西:

What is the simplest way to loop through it. Something like:

foreach ($array as $arr) {
    // help
}

我如何定位键，例如，我想做:

How do I target keys, for example, I want to do:

foreach ($array as $arr) {
    echo '<a href" $key1 ">';
    echo ' $key2 </a>';
}

推荐答案

为了回显这些位，您必须在每个数组中选择它们的索引 -

In order to echo out the bits you have to select their index in each array -

foreach($array as $arr){
    echo '<a href="'.$arr[0].'">'.$arr[1].'</a>';
}

这是一个示例.
