PHP参考多维数组中的特定键和值 [英] PHP reference specific key and value within multidimensional array

问题描述

很抱歉，一个基本的问题，我求助于找不到解决方案(或者我对此感到非常沮丧).

sorry a basic question and I have resorted to asking as I can't find (or I've just got so frustrated with it) the solution.

我希望在多维数组中引用特定的键和值.我的示例数组如下.

I wish to reference a specific key and value within a multidimensional array. My sample array is as below.

因此对于键1并希望引用unique_inter(3)中包含的值

So for key 1 and wish to reference the value contained within unique_inter (3)

有人建议使用此功能或方法吗?

Any anyone advise the function or method to do this?

谢谢

Array
(
    [1] => Array
        (
            [unique_inter] => 3
            [user_id] => 1
        )

    [4] => Array
        (
            [unique_inter] => 1
            [user_id] => 4
        )

)
