本文实例讲述了php实现通过cookie换肤的方法。分享给大家供大家参考。具体如下：

saveStyleSheet.php页面如下：

<?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;   } } ?>

index.php页面如下：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /><title>My Test Page</title><?php include("saveStyleSheet.php"); if(isset($_COOKIE["StyleSheet"])){ ?> <link rel="stylesheet" type="text/css" href="stylesheets/ <?php echo styleSheet($_COOKIE["StyleSheet"]); ?> " /><?php }else{ ?> <link rel="stylesheet" type="text/css" href="stylesheets/style.css" /><?php } ?> </head><body><a href="saveStyleSheet.php?style=1">Style Sheet 1</a><br /><a href="saveStyleSheet.php?style=2">Style Sheet 2</a><br /><a href="saveStyleSheet.php?style=3">Style Sheet 3</a><br /><a href="saveStyleSheet.php">Default Style Sheet</a></body></html>

希望本文所述对大家的php程序设计有所帮助。
