如何对多维数组进行深度排序并保留其键？
如何对多维数组进行深度排序并保留其键？
$array = [
'2' => [
'title' => 'Flower','order' => 3
],'3' => [
'title' => 'Rock','order' => 1
],'4' => [
'title' => 'Grass','order' => 2
]
];
foreach ($array as $key => $row) {
$items[$key] = $row['order'];
}
array_multisort($items,SORT_DESC,$array);
print_r($array);
结果：
Array
(
[0] => Array
(
[title] => Flower
[order] => 3
)
[1] => Array
(
[title] => Grass
[order] => 2
)
[2] => Array
(
[title] => Rock
[order] => 1
)
)
我所追求的是：
Array
(
[2] => Array
(
[title] => Flower
[order] => 3
)
[4] => Array
(
[title] => Grass
[order] => 2
)
[3] => Array
(
[title] => Rock
[order] => 1
)
)
有任何想法吗？
也许这就是你在找什么：
Online Example
原文链接：https://www.f2er.com/php/130329.html保留数组键,使用order列排序并再次组合它们.
$keys = array_keys($array);
array_multisort(
array_column($array,'order'),SORT_NUMERIC,$array,$keys
);
$array = array_combine($keys,$array);
echo '<pre>';
print_r($array);
