array_multisort with maintaining numeric index association [duplicate]

Answer 1

For Your Desired output use this code:

 67, 'specialties' => 1);
$waiters[14] = array('weight' => 41, 'specialties' => 2);
$waiters[58] = array('weight' => 85, 'specialties' => 3);
$waiters[89] = array('weight' => 98, 'specialties' => 4);
$waiters[68] = array('weight' => 86, 'specialties' => 5);
$waiters[31] = array('weight' => 13, 'specialties' => 6);

//ksort($waiters);
//$waiters = array_reverse($waiters, true);
print_r($waiters);
// Obtain a list of waiters
foreach($waiters as $id=>$w){
    $w[$id] = $w['weight'];
}
    foreach ($waiters as $ii => $va) {
        $sorter[$ii] = $va['weight'];

    }

    natcasesort($sorter);
    foreach ($sorter as $ii => $va) {
        $ret[$ii] = $waiters[$ii];
    }

    echo "
";
    $ret = array_reverse($ret, true);
    print_r($ret);
