php - 反向自然排序 PHP 数组而不保留键

Question

我希望以相反的顺序自然地对数组进行排序并且不保留键。例如，我想要这个数组:

[0] => 1-string
[1] => 2-string
[2] => 10-string
[3] => 4-srting
[4] => 3-srting

最后是这样的:

[0] => 10-srting
[1] => 4-string
[2] => 3-string
[3] => 2-string
[4] => 1-string

我已经用 usort($array, 'strnatcmp'); 搞定了但它不是相反的顺序。 array_reverse() 之后没有帮助。

有什么想法吗？

Answer 1

我对“array_reverse() after doesn't help”有点疑惑。因为

<?php
echo PHP_VERSION, "\n";

$x = array( 
    '1-string',
    '2-string',
    '10-string',
    '4-srting',
    '3-srting'
);

natsort($x);
$x = array_reverse($x, false);
print_r($x);

打印

5.3.8
Array
(
    [0] => 10-string
    [1] => 4-srting
    [2] => 3-srting
    [3] => 2-string
    [4] => 1-string
)
