Question

I’m look to naturally sort an array, in reverse order and not preserve the keys. For example, I’d like this array:

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

To end up like this:

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

I’ve got it close with usort($array, ‘strnatcmp’); but it’s not in reverse order. array_reverse() after doesn’t help.

Any ideas?

Answer 1

I’m a bit puzzled about “array_reverse() after doesn’t help.” because

<?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);

prints

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