PHP array - appending number (value) to string (key) for each element

I have an array like

$a = array
     (   
        "Leafs",  
        "Sabres",  
        "Red Wings",  
        "Flyers"
     );

that I shuffle shuffle($a);

The resultant array could be:

Array
(
    [0] => Sabres
    [1] => Red Wings
    [2] => Leafs
    [3] => Flyers
)

With the resultant array, I now want to append a sequential number twice starting with 1 to each element in the array such that $a becomes:

Array
(
    [1] => Sabres
    [1] => Red Wings
    [2] => Leafs
    [2] => Flyers
)

The number ends with 2 in this array, but should continue until there are no more elements to number in the array. How can this be done programmatically?

You can't have array with not unique keys. So `[1] => Sabres [1] => Red Wings` is wrong. What is your the real problem? – splash58 Oct 16 '19 at 17:01

Array index must be unique. You can do a multi-dimentional array rather `array ( 1 => array( 'Sabres', 'Red Wings', ), 2 => array( 'Leafs',, 'Flyers' ) )` – Teddy Patriarca Oct 16 '19 at 17:04
@TeddyPatriarca Maybe, OP only wants to use array_chunk. Or, maybe, some else. – splash58 Oct 16 '19 at 17:12
@splash58 can I set `Sabres` as the key and `1` as the value? – machump Oct 16 '19 at 17:18
If values are unique, you can – splash58 Oct 16 '19 at 17:19
What is your end purpose? Do you want to get pairs? – freeek Oct 16 '19 at 17:20
@freeek I want to pair each element with another element randomly, the number assignment is to designate the pairs – machump Oct 16 '19 at 17:21

`array_chunk($array,2)` – splash58 Oct 16 '19 at 17:22
Then use @splash58 solution :) – freeek Oct 16 '19 at 17:24
