PHP Foreach Arrays and objects

Question

I have an array of objects; running print_r() returns the output below;

Array
(
    [0] => stdClass Object
        (
            [sm_id] => 1
            [c_id] => 1
        )
    [1] => stdClass Object
        (
            [sm_id] => 1
            [c_id] => 2
        )
)
