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：

<link rel="stylesheet" type="text/css" href="stylesheets/ <?php echo styleSheet($_COOKIE["StyleSheet"]); ?> " />

<?php
