Php reverse array is not working [duplicate]

Question

I am developing a new website, and I have a quetion.

Input array:

Array ( [1319] => ####,[1316] => ###)

I have an array and I want to revese him, after the reverse the array would be like this:

Expected output:

Array ( [1316] => ###,[1319] => ####)

but when i'm using array_reverse function, it doesnt work for me, I got this array:

Array ( [0] => ###,[1] => ####)

Why it is happen?

For preserving keys you just pass second parameter to true in array_reverse.

$array=Array ( 1319 => "####",1316 => "###");
print_r(array_reverse($array,true));

you can try this:

$a = []; //your array

$keys = array_keys($arr);
$values = array_values($arr);

$rv = array_reverse($values);

$newArray = array_combine($keys, $rv);
