How to Retrieve Data from Session Array Variable in PHP

session array variable in php can store more items or data in a single variable but these are not available in different pages for use. Any ordinary ( or normal ) array will loose its data as page execution ends. We have to transfer the array each time the visitor moves away from one page to other. In some applications we need to retain the data as long as the visitor is active at site. Shopping cart is the best example for this. Visitor moves between different pages and adds items to the shopping cart. We have to carry the shopping cart to all the pages along with the visitor. Visitor can add or remove items from the cart from any page.
