Share it with you for your reference. The details are as follows:

The saveStyleSheet. php page is as follows:

<?php function styleSheet($currentCookie){   // Get Current Style Sheet   $currentCookie = $_COOKIE["StyleSheet"];   // Get New cookie file name   switch($_GET['style']){     case 1:       $value = 'style1.css';     break;     case 2:       $value = 'style2.css';     break;     case 3:       $value = 'style3.css';     break;     default:       $value = 'style.css';     break;   }   // If the user views this page, without using   // style=... then set cookie to the default   if(!isset($_GET['style'])){     $value = 'style.css';   }   // If the new value doesn't equal the old value allow cookie change   if(isset($value)||$currentCookie!=$value||isset($currentCookie)){     setcookie("StyleSheet", $value, time()+600000); /* expires in 10,000 hours*/     return $_COOKIE["StyleSheet"];   }else{     return $_COOKIE["StyleSheet"];   }   if(isset($_GET['style'])){     header("Location: ".$_SERVER['HTTP_REFERER']);     exit;   } } ?>
