Looping over arrays and objects is a pretty common task  and it s good that you re wanting to learn how to do it  Generally speaking you can do a foreach loop which cycles over each member  assigning it a new temporary name  and then lets you handle that particular member via that name   foreach   arr as  item        echo  item- gt sm id      In this example each of our values in the  arr will be accessed in order as  item  So we can print our values directly off of that  We could also include the index if we wanted   foreach   arr as  index   gt   item        echo  Item at index   index  has sm id value   item- gt sm id
