php - insert item at any array position with key

Question

This is my array:

array(
99 => 100,
53 => 200,
29 => 300
)

I would like to add a new item at index 2 like this:

array(
99 => 100,
53 => 200,
36 => 'new',
29 => 300
)

I only found a solution to add a new item without own key, have anyone an idea?

$table[36] = 'new'

In case of duplicate entry, you should reinsert the entry with a new key before.

$table[] = $table[36];
$table[36] = 'new';

If the array is sorted and it looks like this.

You can add the new element:

$array[36] = 'new';

and sort it afterwards:

krsort($array);
