I have a array in PHP like so
$somevar = array(1, 5, 2, 7, 17, 2, 13);
I want to sort the array, but not move the values around, so I get another array with the order of the index/keys.
So my new array would be something like
{0, 2, 5, 1, 3, 6, 4}
Which is the order of the keys
This should work for you:
<?php
$somevar = array(1, 5, 2, 7, 17, 2, 13);
$newArray = array_values($somevar);
asort($newArray);
$newArray = array_keys($newArray);
print_r($newArray);
?>
Output:
Array ( [0] => 0 [1] => 2 [2] => 5 [3] => 1 [4] => 3 [5] => 6 [6] => 4 )
Try this..
$somevar = array(1, 5, 2, 7, 17, 2, 13);
print_r($somevar);
//your array
Array ( [0] => 1 [1] => 5 [2] => 2 [3] => 7 [4] => 17 [5] => 2 [6] => 13 )
asort($somevar);
print_r($somevar);
//After sort
Array ( [0] => 1 [2] => 2 [5] => 2 [1] => 5 [3] => 7 [6] => 13 [4] => 17 )
print_r(array_keys($somevar));
//array key sorted array
Array ( [0] => 0 [1] => 2 [2] => 5 [3] => 1 [4] => 3 [5] => 6 [6] => 4 )
