Getting values from arrays containing stdClass PHP objects

I'm obtaining information from the Facebook Graph API that returns an array that contains several stdClass Objects. I can easily read the "top" level items such as $myGraph['id'] = 123111193 in the example below.

Can anyone show me how to get data from the stdClass Objects, for example School Name in the following example created with print_r()?

    Array
    (
        [id] => 123111193
        [education] => Array
    (
        [0] => stdClass Object
            (
                [school] => stdClass Object
                    (
                        [id] => 108177302537907
                        [name] => State College Area High School
                    )

                [type] => High School
                [year] => stdClass Object
                    (
                        [id] => 117615364954534
                        [name] => 1975
                    )

            )

        [1] => stdClass Object
            (
                [concentration] => Array
                    (
                        [0] => stdClass Object
                            (
                                [id] => 193334910691838
                                [name] => Individual and Family Studies
                            )

                    )

                [school] => stdClass Object
                    (
                        [id] => 113618111985274
                        [name] => Pennsylvania State University
                    )
