php如何实现cookie换肤功能
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。
