Question on type casting for SOAP

I'm trying to merge from nuSOAP to the PHP5 SOAP ext and I'm getting a fatal error b>Fatal error</b>: Cannot use object of type stdClass as array when I var_dump the results of my soap call I noticed the array it returns is an array of objects? array(6) { [0]=> object(stdClass)#12 (6) {

    ["N1"]=>
    int(88)
    ["N2"]=>
    int(98)
    ["S1"]=>
    string(12) "this is a test"
    ["S2"]=>
    string(9) "http"
    ["S3"]=>
    string(3) "tcp"
    ["S4"]=>
    string(24) "Linux Configuration Tool"

} however nusoap returns as a standard array and the only way I got the old code to work was to cast as an array as I loop through the results foreach ($array as $key=>$value) $value = (array)$value; which sucks for backwards compatibility. Anyone have any better ideas on how I might be able to resolve the issue?
