Question

我有3个不同的数组，它们具有相同的键，但值不同

Array 1
(
[product_category_39] => Living Room
[product_category_40] => Dining Room
[product_category_38] => Bedroom
[product_category_44] => Kids Room
[product_category_43] => Home Office
[product_category_42] => Decor
[product_category_11] => Furnishings
[product_category_41] => Kitchen & Table Top
[product_category_45] => Bath
)

Array 2
(
[product_category_40] => std Object()
[product_category_39] => std Object()
[product_category_45] => std Object()
[product_category_38] => std Object()
[product_category_11] => std Object()
[product_category_42] => std Object()
[product_category_41] => std Object()
[product_category_43] => std Object()
[product_category_44] => std Object()
)

Array 3
(
[product_category_44] => val6
[product_category_39] => xyz
[product_category_42] => data5
[product_category_41] => pqr
[product_category_45] => val2
[product_category_11] => lmn
[product_category_38] => data12
[product_category_43] => abc
[product_category_40] => val 1
)

我想根据我的第一个数组的键对这3个数组进行排序。密钥的顺序应与第一个数组中的顺序相同。有什么办法可以做到这一点。

排序后应该看起来像

Array 1
(
[product_category_39] => Living Room
[product_category_40] => Dining Room
[product_category_38] => Bedroom
[product_category_44] => Kids Room
[product_category_43] => Home Office
[product_category_42] => Decor
[product_category_11] => Furnishings
[product_category_41] => Kitchen & Table Top
[product_category_45] => Bath
) 


Array 2
(
[product_category_39] => std Object()
[product_category_40] => std Object()
[product_category_38] => std Object()
[product_category_44] => std Object()
[product_category_43] => std Object()
[product_category_42] => std Object()
[product_category_11] => std Object()
[product_category_41] => std Object()
[product_category_45] => std Object()
)

Array 3
(
[product_category_39] => xyz
[product_category_40] => val 1
[product_category_38] => data12
[product_category_44] => val6
[product_category_43] => abc
[product_category_42] => data5
[product_category_11] => lmn
[product_category_41] => pqr
[product_category_45] => val2
)

Answer 1

$arr1 = array(
    'b'=>1,
    'a'=>2,
    'c'=>3
);

$arr2 = array(
    'a'=>4,
    'b'=>5,
    'c'=>6
);

function sort_by_set($arr1,$arr2){
    foreach($arr1 as $key=>$value){
        $arr_new[$key] = $arr2[$key];
    }
    return $arr_new;
}

$arr2_new = sort_by_set($arr1,$arr2);
print_r($arr2_new);

这是重建，可能不是排序

Answer 2

另外，你可以使用这个技巧：

$first = array(
    'one' => 1,
    'three' => 3,
    'two' => 2,
);
$second = array(
    'two' => 'two',
    'one' => 'one',
    'three' => 'three'
);
uksort($second, function ($a, $b) use ($first) {
    foreach ($first as $key => $v) {
        if ($a == $key) {
            if ($b == $key) {
                return 0;
            }
            return -1;
        }
        if ($b == $key)
            return 1;
    }
    return 1;
});
var_dump($second);

在您的情况下，使用多个数组，您可以取消回调函数并将$first用作global。

请参阅以下链接：Sort array using another array keys

它回答了你的问题，或者至少会给你一个如何处理它的开始。祝你好运！

$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] ;
}

根据第一个数组的键排序多个
