array(
    \'firstName\' => \'Joe\',
    \'lastName\'  => \'Smith\'
    )

I need to loop over every elemen

unset it first in case it is already in the proper format, otherwise you will remove what you just defined:

foreach($array as $key => $value)
    {
        unset($array[$key]);
        $array[ucfirst($key)] = $value;
    }
