Question

我想按升序对值进行排序。

我尝试了ksort和其他排序示例。

Array
(
    [0] => stdClass Object
        (
            [tenure] => 1 year to less than 2 years
        )

    [1] => stdClass Object
        (
            [tenure] => 10 years to less than 15 years
        )

    [2] => stdClass Object
        (
            [tenure] => 15 years or more
        )

    [3] => stdClass Object
        (
            [tenure] => 2 years to less than 5 years
        )

    [4] => stdClass Object
        (
            [tenure] => 5 years to less than 10 years
        )

)

我想对上述数组的权属值进行排序。

Answer 1

由于所有值均以数字开头，因此您可以将它们转换为整数并使用usort对它们进行排序：

usort($array, function ($a, $b) { return (int)$a->tenure - (int)$b->tenure; });
print_r($array);

输出：

Array (
  [0] => stdClass Object (
    [tenure] => 1 year to less than 2 years
  )
  [1] => stdClass Object (
    [tenure] => 2 years to less than 5 years
  )
  [2] => stdClass Object (
    [tenure] => 5 years to less than 10 years
  )
  [3] => stdClass Object (
    [tenure] => 10 years to less than 15 years
  )
  [4] => stdClass Object (
    [tenure] => 15 years or more
  )
)

Answer 2

您可以使用核心array_multisort

array_multisort(array_column($array, 'tenure'),   
SORT_ASC, SORT_NATURAL, $array);

Answer 3

您可以使用array_walk，ksort，也可以将object更改为array

$arr = (array) $object;

然后尝试这个

$res=[];
array_walk($arr, function($v, $k) use (&$res){
  $key = substr($v['tenure'], 0, strspn($v['tenure'], "0123456789"));
  $res[$key] = $v;
});
ksort($res);
