PHP的 - 主键排序的数组通过关键字来查找另一个数组的订单 [英] php - sort an array by key to match another array's order by key

问题描述

我有两个阵列，都具有相同的键（不同的值），但是阵列＃2以不同的顺序。我希望能够求助于第二阵列所以它是在相同的顺序第一阵列

I have two arrays, both have the same keys (different values) however array #2 is in a different order. I want to be able to resort the second array so it is in the same order as the first array.

是否有一个功能，可以迅速地做到这一点？

Is there a function that can quickly do this?

推荐答案

我想不出任何把我的头顶部，但如果密钥是相同的在这两个数组又何尝不是在第一个循环刚并使用其键顺序使用从第二一个值，以创建一个新的阵列？

I can't think of any off the top of my head, but if the keys are the same across both arrays then why not just loop over the first one and use its key order to create a new array using the the values from the 2nd one?

$arr1 = array(
    'a' => '42', 
    'b' => '551',
    'c' => '512',
    'd' => 'gge',
) ;


$arr2 = array(
    'd' => 'ordered',
    'b' => 'is',
    'c' => 'now',
    'a' => 'this', 
) ;

$arr2ordered = array() ;

foreach (array_keys($arr1) as $key) {
    $arr2ordered[$key] = $arr2[$key] ;
}
