<? $custom_sections_table = $custom_fld
->
display_sections($item_details, $page_handle, true, $item_details['item_id'], $db
->
main_category($item_details['category_id'])); ?>

A friend sent the above code to me. What does the -> stand for?

a->b means that b is a member of a, e.g., given an object $x of a class with member function m(), we could call m() by writing $x->m().

In your case, $custom_fld is (presumably) an object of a class with a member function named display_sections. This member function returns an object of a class with a member function named main_category.
