Need to change array key value during asort function

Question

Hi I have below array,

$arr = Array ( [0] => 248 [1] => 247 )

Using asort() I get below result,

$arr = Array ( [1] => 247 [0] => 248 )

But I need the below format,

$arr = Array ( [0] => 247 [1] => 248 )

Need to sort only the value not key. Is there any default function in php for my expected result?

You can use array_values to reset the keys after sorting.

<?php

$arr = [248, 247];

asort($arr);

print_r(array_values($arr));

will give:

Array
(
    [0] => 247
    [1] => 248
)

BTW, I ain't sure why you use asort, but when you use sort function to sort, it resets the keys.

From the manual:

asort - Sort an array and maintain index association

sort - Sort an array (Your Exact Need)
