Ok, I have an array like so, but it's not guaranteed to be laid out in this order all of the time...

$array = array(
    'sadness' => array(
        'info' => 'some info',
        'info2' => 'more info',
        'value' => 'value',
    ),
    'happiness' => array(
        'info' => 'some info',
        'info2' => 'more info',
        'value' => 'the value',
    ),
    'peace' => array(
        'info' => 'some info',
        'info2' => 'more info',
        'value' => 'the value',
    )
);

Ok, and I'd like to throw in this array right after the happiness key is defined. I can't use the key of "peace" since it must go directly after happiness, and peace might not come after happiness as this array changes.

So here's what I need to add after happiness...

$another_array['love'] = array(
    'info' => 'some info',
    'info2' => 'more info',
    'value' => 'the value of love'
);

So the final output after it gets inputted directly after happiness should look like this:

$array = array(
    'sadness' => array(
        'info' => 'some info',
        'info2' => 'more info',
        'value' => 'value',
    ),
    'happiness' => array(
        'info' => 'some info',
        'info2' => 'more info',
        'value' => 'the value',
    ),
    'love' => array(
        'info' => 'some info',
        'info2' => 'more info',
        'value' => 'the value of love',
    ),
    'peace' => array(
        'info' => 'some info',
        'info2' => 'more info',
        'value' => 'the value',
    )
);

Can someone please give me a hand with this. Using array_shift, array_pop, or array_merge doesn't help me at all, since these go at the beginning and at the end of the array. I need to place it directly after a KEY position within $array.

Thanks :)
