Order Array by 2nd value

Question

I have an array as follows

Array
(
[1845267] => 2
[1845256] => 2
[1845260] => 2
[33636] => 1
[67376] => 2
[73250] => 1
[125313] => 2
[142062] => 1
[342520] => 2
[357301] => 2
[357303] => 1
[404419] => 1
[408957] => 1
[415891] => 2
[455894] => 1
[460119] => 1
[582332] => 1
[582333] => 1
[602886] => 1
)

My aim is to order them by the single digit value so the output would put the 2's(or highest number) to the top

Array
(
[1845267] => 2
[1845256] => 2
[1845260] => 2
[415891] => 2
[125313] => 2
[67376] => 2
[342520] => 2
[357301] => 2
[33636] => 1
[73250] => 1
[142062] => 1
[357303] => 1
[404419] => 1
[408957] => 1
[455894] => 1
[460119] => 1
[582332] => 1
[582333] => 1
[602886] => 1
)

FYI, thats not the "second value". That's the "value", and the big numbers, like 1845267, are the "key"s. — Eric

Try with the arsort function:

arsort — Sort an array in reverse order and maintain index association

Example:

arsort($array);
// done, $array is now sorted

I am using the system below to generate the array above, when I attempt to print_r(arsort($weights)); the output is simply the digit 1. $weights = array_count_values($weight); print_r(arsort($weights));

arsort() doesn't return the array, it sorts the array in place. Do arsort($weights); print_r($weights);
