weird array behaviour

I have a function which returns a mulit-dimensional array, but the array which is returned doesn't "work" for some reason :/ If i print the array within the function using while (list($key) = each($myArray)) { while (list($key2, $value2) = each($myArray[$key])) { print $key . " : " . $key . " : " . $value; } } it works fine but doing the same thing after the array has been returned jus yields -- Warning: Variable passed to each() is not an array or object in ... refering to $myArray[$key]; even though if i print $myArray[$key] it tells me that it's an Array :/ Thanks. Nick.
