从对象获取多个数据

Question

i m using mind body api to fetch data. i have n object that contains the following data, i need to fetch all the id firstname and lastname and store it in database. i have shown the data here only till [3] => stdClass Object, but the original list is long.

Array
(
    [0] => stdClass Object
        (
            [ID] => 100000173
            [FirstName] => a
            [LastName] => b
        )

    [1] => stdClass Object
        (
            [ID] => 100000174
            [FirstName] => c
            [LastName] => d
        )

    [2] => stdClass Object
        (
            [ID] => 100000175
            [FirstName] => e
            [LastName] => f
        )

    [3] => stdClass Object
        (
            [ID] => 100000176
            [FirstName] => g
            [LastName] => h
        )
)

I received the above result from the following code..

$MBclients = $classService->GetClients(array());
if(intval($MBclients->GetClientsResult->ResultCount) > 0)
    {
        echo "<pre>";print_r($MBclients->GetClientsResult->Clients->Client);//die;
    }   

The code that i tried to fetch data is

$info = $MBclients->id; 
echo $info; 

But it didn't showed any result. can anyone tell how to fetch the result
