PHP code to achieve a shopping cart storage cycle of 1 days

Shopping cart cookies are stored for 1 days. Note: Browsers must support cookies to be able to use them. This article mainly and everyone introduced in detail the PHP implementation of the storage cycle for 1 days shopping cart category, with a certain reference value, interested in small partners can refer to, hope to help everyone.

Example code:

<?php/** * Shopping cart cookies are stored for 1 days Note: The browser must support cookies to be able to use */class Cartapi {private $CartArray = array ();//Store two-dimensional array of cart Private $CartCount; Statistics Shopping Cart number public $Expires = 86400; Cookie expiration time, if 0 is not saved to local unit in seconds/** * constructor Initialization action if $id is not empty, add directly to cart */Public Function __construct ($Id = "", $Nam E = "", $Price 1 = "", $Price 2 = "", $Price 3 = "", $Count = "", $Image = "", $Expires = 86400) {if ($Id!
