Here is a function that recursively flattens an multidimensional array while maintaining keys. Hopefully it is useful to someone..

Example Input:

Array
(
    [name] => John Doe
    [email] => [email protected]
    [addresses] => Array
        (
            [1] => Array
                (
                    [address] => 555 Somewhere
                    [city] => Podunk
                    [state] => CA
                    [zip] => 90120
                )

            [2] => Array
                (
                    [address] => 333 Someother Place
                    [city] => Podunk
                    [state] => CA
                    [zip] => 91103
                )

        )

)
Example output:
Array
(
    [name] => John Doe
    [email] => [email protected]
    [address1] => 555 Somewhere
    [city1] => Podunk
    [state1] => CA
    [zip1] => 90120
    [address2] => 333 Someother Place
    [city2] => Podunk
    [state2] => CA
    [zip2] => 91103
)

<?
function flattenArray($array,$keyname='')
{
    $tmp = array();
    foreach($array as $key => $value)
    {
        if(is_array($value))
            $tmp = array_merge($tmp,flattenArray($value,$key));
        else
            $tmp[$key.$keyname] = $value;
    }
    return $tmp;
}
?>
