Re: PHP Manual, Chapter 13. Classes and Objects

the -> operator is the way to access methods of a class, 
just like image.src would be in javascript

| In the example on the first page of chapter 13, there's this expression:
| 
| <?php 
| class Cart { 
| var $items; // Items in our shopping cart 
| // Add $num articles of $artnr to the cart
| function add_item ($artnr, $num) { 
| $this->items[$artnr] += $num;
| }
| // Take $num articles of $artnr out of the cart
| function remove_item ($artnr, $num) { 
| if ($this->items[$artnr] > $num) { 
| $this->items[$artnr] -= $num; 
| return true; 
| } else { return false;  }}}
| ?>
| what is the "->" operator in this context?
