How to get the array elements of a specific key from an associative array in following scenario?

Question

I've on associative array titled $group_list. When I print it using print_r($grouop_list) it prints following content:

Pages_Component_Controller_List Object

)
    [_sModule:Phpfox_Component:private] => pages
    [_sComponent:Phpfox_Component:private] => controller/list
    [_sCacheVar:Phpfox_Component:private] => 
)

Actually I want all the array elements from belonging to data key only. How should I get this data?

Please help me.

Thanks.

Answer 1

Try it:

echo $grouop_list['data'][0]->title;

echo $grouop_list['data'][0]->time_stamp;

Answer 2

Your $group_list is most probably not an array but indeed an object.

To access the data array you simply use the arrow operator (->):

$data = $group_list->data;
