按整数值排序PHP数组，同时保持Key [duplicate]

Question

This question already has an answer here:

• sort array in DESC order 4 answers

I have an array like this

[Title 1] => 2
[Title 2] => 4
[Title 3] => 3
[Title 4] => 1

All I'm trying to do is sort the integer value in the array, to get an output like this:

[Title 2] => 4
[Title 3] => 3
[Title 1] => 2
[Title 4] => 1

I don't think it matters, but my array is created by the array_count_values function.

$array = array_count_values($originalarray);

I've looked through the manual on PHP: Array Sorting but can't get anything to work.

I've tried a few things that look like they might work.

$newarray = arsort($array);

This just outputs 1

same with rsort.

The closest I've come is by using array_multisort by using it as such:

$array = array_count_values($originalarray);
$newarray = array_multisort($array, SORT_NUMERIC, SORT_DESC);

Now if I do a print_r($array) it outputs like this:

[Title 2] => 4
[1] => 3
[Title 1] => 2
[2] => 1

Meaning it's, for some reason, and seemingly randomly, destroying the key value in the array and putting in place 1, 2, etc in place of Title #

This seems like it would be so easy, yet I've been trying multiple things without luck. Can anyone shine some light on this for me?

Answer 1

sort functions in php return boolean not an array - http://php.net/manual/en/function.arsort.php Sort function will update the array you put as parameter Should be like this

<?php
$array = [];
arsort($array);
var_dump($array);
