            [description] => Example Description
        )
    [1] => Array
        (
            [index-id] => 32
            [title] => Example Title
            [description] => Example Description
        )

Short solution using array_column and array_combine functions:

// $arr is your initial array
$result = array_combine(array_column($arr, 'index-id'), $arr);

$temp = [];
foreach($arr as $k => $v){
    $temp[$v['index-id']] = $v;
}
print_r($temp);

Where $temp is result array, $arr is your array.
