在多维数组中搜索值 PHP [英] Searching Multidimensional Array for Value PHP

问题描述

我觉得这是一个很简单的问题，但我似乎在任何地方都找不到答案.

I feel like this is a pretty easy question, but I can't seem to find the answer anywhere.

$array = ('colors' => array('red','orange'),
          'numbers'=> array('one','two')
         );

如何对 $array 执行搜索以确定 colors 是否包含 red 的值?

How do a perform a search on the $array to determine if colors contains a value of red?

提前致谢.

推荐答案

没有内置的数组函数来做到这一点.在您给出的特定情况下，最简单的方法是:

There is no built in array function to do this. Thes simplest way to to it in the specific case youve given is to do:

$hasRed = (isset($array['colors'] && in_array('red', $array['colors']));
