array_combine仅返回最后一个值 [英] array_combine is return only last value

问题描述

对于foreach loop，我有两个不同的array，所以我决定将它们组合并一起运行到foreach loop，但是它只返回数组的最后一个值.

I have two different array for foreach loop so i decide to combine them and run in to foreach loop together but it's returning only last value of array.

数组1:$FileType

Array 1: $FileType

Array
(
    [0] => image/png
    [1] => image/png
    [2] => image/png
    [3] => image/png
    [4] => image/png
    [5] => image/png
)

阵列2:$FileName

Array 2: $FileName

Array
(
    [0] => post2.png
    [1] => post5.png
    [2] => post6.png
    [3] => post7.png
    [4] => post8.png
    [5] => post11.png
)

这是我的代码:

foreach(array_combine($FileType,$FileName) as $Type => $Name){
                echo $Type .":". $Name;
            }

仅返回最后一个值

返回:

image/png:post11.png

推荐答案

array_combine 并非如此.

您可以轻松完成

  foreach($FileName as $id=>$Name)
  {
      echo $FileType[$id] .":". $Name;
  }

假设两个数组的大小和键都相同

Assuming both arrays are of same size and same keys
