arrays

I have an array of countries that I will be using in a select menu:

array(
    [0] => " -- Select -- "
    [1] => "Afghanistan"
    [3] => "Albania"
    [4] => "Algeria"
    [39] => "Canada"
    [47] => "USA"
)
//etc...

I want to copy create copies of the Canada and USA entries and place them at the front of my array. So the array should end up looking like this:

array(
    [0] => " -- Select -- "
    [47] => "USA"
    [39] => "Canada"
    [1] => "Afghanistan"
    [3] => "Albania"
    [4] => "Algeria"
    [39] => "Canada"
    [47] => "USA"
)
//etc...

The array keys correspond to their ID in the database, so I can't change the keys. How can I achieve this?
