在php数组中查找兄弟键的值 [英] Find value of sibling key in php array

问题描述

我在 PHP 中有一个数组，这是一个片段:

I have an array in PHP, here is a snippet:

$locations = array(
    array(
        "id" => 202,
        "name" => "GXP Club - Fable"
    ),

    array (
        "id" => 204,
        "name" => "GXP Club - Gray"
    )
);

我知道(从 GET)是 ID (202).我想显示的是显示结果"( where $locations[?][id] = $_GET['id'] { echo $locations[?][name] } )- 请原谅我使用伪代码.

What I know (from a GET) is the ID (202). What I would like to display is "Showing results for " ( where $locations[?][id] = $_GET['id'] { echo $locations[?][name] } ) - if you will pardon my use of pseudo code.

不确定哪个函数是最好的，或者我是否需要遍历整个数组才能找到它.谢谢.

Not sure what function is best or if I need to loop over the whole array to find that. Thanks.

进一步澄清.我需要学习给定 [id] 的 [name]

for further clarification. I need to learn the [name] given the [id]

推荐答案

foreach( $locations as $arr ) {
    if($arr['id'] == $_GET['id']) {
        echo $arr['name'];
        break;
    }
}

这应该可以解决问题.
