Sort a flat array by values in a descending direction and preserve the keys

Please how do I sort the below array

Array
(
    'ben' => 1.0,
    'ken' => 2.0,
    'sam' => 1.5
)

to

Array
(
    'ken' => 2.0,
    'sam' => 1.5,
    'ben' => 1.0
)
Solution

  • try this.

    <?php
$my_array = array('ben' => 1.0, 'ken' => 2.0, 'sam' => 1.5);

arsort($my_array);
print_r($my_array);
?>

    The arsort() function sorts an array by the values in reverse order. The values keep their original keys.
