多维数组成单层阵列的PHP [英] multi-dimensional array into a single layered array PHP

问题描述

我已经返回下面的数组

 阵列
    （
        [0] =＆GT;排列
            （
                [UID] =＆GT; 616941445
            ）        [1] =＆GT;排列
            （
                [UID] =＆GT; 1354124203
            ）    ）
 

不过，我想只是一个单层排列，所以我想这样的事情。

 阵列
（
[0] =＆GT; 616941445
[1] =＆GT; 1354124203
）
 

解决方案

 的foreach（$ $作为重点编曲= GT; $ VAL）{
  $改编[$关键] = $ VAL ['UID'];
}
 

I have the following array being returned

Array
    (
        [0] => Array
            (
                [uid] => 616941445
            )

        [1] => Array
            (
                [uid] => 1354124203
            )

    )

However I want just a single layered array, so i would like something like this.

Array
(     
[0] => 616941445
[1] => 1354124203
)

解决方案

foreach ($arr as $key => $val) {
  $arr[$key] = $val['uid'];
}
