我有 2 个数组：

Array
(
    [field_bathrooms] => Bathrooms
    [field_bedrooms] => Bedrooms
    [field_king_beds] => King Beds
    [field_kitchen] => Kitchen
    [field_queen_beds] => Queen Beds
    [field_sleeps_max] => Sleeps
    [field_sofa_beds] => Sofa Beds
    [field_sqft] => Square Footage
    [field_twin_beds] => Twin Beds
)

Array
(
    [0] => Bathrooms
    [1] => Square Footage
    [2] => King Beds
    [3] => Sofa Beds
    [4] => Sleeps
    [5] => Twin Beds
    [6] => Queen Beds
    [7] => Kitchen
    [8] => Bedrooms
)

我想通过第二个数组的键对第一个数组进行排序，所以最终结果是这样的数组：

Array(
[field_bathrooms] => Bathrooms
[field_sqft] => Square Footage
[field_king_beds] => King Beds
[field_sofa_beds] => Sofa Beds
[field_sleeps_max] => Sleeps
[field_twin_beds] => Twin Beds
[field_queen_beds] => Queen Beds
[field_kitchen] => Kitchen
[field_bedrooms] => Bedrooms
)

我必须承认我对 PHP 和 MySQL 还比较陌生。希望你们中的某个人能让我重回正轨。

您可以编写一个引用地图（倒数第二个数组）的自定义排序函数：

$map = array_flip($second_array);

uasort($first_array, function($a, $b) use ($map) {
    return $map[$a] - $map[$b];
});

print_r($first_array);

也可以看看：array_flip() uasort()

这将在一行中完成您想要的操作：

$result = array_flip( array_replace( array_flip($arr2), array_flip($arr1) ) );

print_r($result);

解释一下：由于您想按数组中的值而不是键进行排序，因此我们使用array_flip翻转每个数组中的数组和值。然后，我们用array_replace第一个数组中的匹配值替换第二个数组中的值（保持当前顺序）。然后我们使用array_flip将键和值放回我们开始的方式。

你的代码可以是这样的：

$indx;
for ($i = 0; i < Aarray1size; i++)
{

    $key = Array1[i];
    for ($j = 0; j < array2size; j++)
    {
         if(Array2[j] == $key)
          {
                index = j;
          }
    }
    Array1[i] = Array2[index];
    index = 0;

}

<?

$arr2 = array(

        {
            $result[$k] = $v;
            unset($arr1[$k]);
            break;
        }
    }
}
var_dump($result);

$array3 = array();
foreach ($array2 as $val)

  $key = array_search($val, $array1);
  $array3[$key] = $val;
}

var_dump($array3);
