obj in array?

Hi folks I'm hacking on a SOAP2 solution towards Magento and have retrieved the catalog in an array, but i'm having trouble accessing the values of the array cause there's an object in it. This is a var_dump of $my_array: array(14) { [0]=> object(stdClass)#2 (2) {

    ["set_id"]=>
    int(44)
    ["name"]=>
    string(7) "Cameras"

} [1]=> object(stdClass)#3 (2) {

    ["set_id"]=>
    int(38)
    ["name"]=>
    string(11) "Cell Phones"

} how do I access for instance set_id in $my_array[0]? I tried declaring an instance of $my_array[0] but that fails too: "Fatal error: Cannot use object of type stdClass as array " -- Kind regards Kim Emax - masterminds.dk
