如何检查如果一个数组包含在PHP中一个特定的值？ [英] How can I check if an array contains a specific value in php?

问题描述

我有一个表格，创建一个数据数组，我想看看它是否包含一个特定的值，让用户知道它的存在。这是我的数组：

I have an array of data created by a form that and I would like find out if it contains a specific value and let the user know that it is there. This is my array:

Array ( [0] => kitchen [1] => bedroom [2] => living_room [3] => dining_room) 

和我想这样做：

if(Array contains 'kitchen') {echo 'this array contains kitchen';}

什么是做上述的最佳方式？

What is the best way to do the above???

推荐答案

使用 in_array（）功能。

$array = array('kitchen', 'bedroom', 'living_room', 'dining_room');

if (in_array('kitchen', $array)) {
    echo 'this array contains kitchen';
}
