saveStyleSheet.PHP,经测试代码如下：
/**
* 通过cookie更换皮肤样式表
*
* @param
* @author 编程之家 jb51.cc jb51.cc
**/
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;
}
}
