php multi-dimensional array provides three levels of depth instead of two

Question

When I execute the code below: Code:

<?php

$data = array();
$jim = array('Jim'=>1);
$bob = array('Bob'=>1);
$data['abc'][] = $jim;
$data['abc'][] = $bob;

print_r($data);
?>

I receive the following output:

    Array
(
    [abc] => Array
        (
            [0] => Array
                (
                    [Jim] => 1
                )

            [1] => Array
                (
                    [Bob] => 1
                )
        )
)

What I am expecting is the following output:

   Array
(
    [abc] => Array
        (
            [Jim] => 1
            [Bob] => 1
        )

)

How can I achieve this? To rephrase the question, how can I keep it to a single sub-array per a supplied key?

$data = array();
$jim = array('Jim'=>1);
$bob = array('Bob'=>1);
$data['abc'] = array_merge($jim, $bob);

print_r($data);

Still this will produce 3 levels

@Darhazer That's what the OP required

His title kinda contradicts his question. He can just remove the [] if he wants to keep it at two levels.

I have updated my original question because Darhazer provided the output I was expecting.

You have to understand the problem, not the question, otherwise you fall in the trap of the XY problem ;)

You are creating array ($data['abc']) which contains an array ([]) of arrays($jim, $bob) It's the same as writing:

$data['abc'][0] = array('jim' => 1);
$data['abc'][1] = array('bob' => 1);

What you want is probably:

$data['abc'] = array();
$data['abc'] = array_merge($data['abc'], $jim, $bob);

Jim and Bob are array indexes by your own declaration, you have to change them first

<?php

$data = array();
$data['abc']["Jim"] =1;
$data['abc']["Bob"] = 2;

print_r($data);
?>
