php实现通过cookie换肤的方法
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
functionstyleSheet($currentCookie){
//GetCurrentStyleSheet
$currentCookie=$_COOKIE["StyleSheet"];
//GetNewcookiefilename
switch($_GET['style']){
case1:
$value='style1.css';
break;
case2:
$value='style2.css';
break;
case3:
$value='style3.css';
break;
default:
$value='style.css';
break;
}
//Iftheuserviewsthispage,withoutusing
//style=...thensetcookietothedefault
if(!isset($_GET['style'])){
$value='style.css';
}
//Ifthenewvaluedoesn'tequaltheoldvalueallowcookiechange
if(isset($value)||$currentCookie!=$value||isset($currentCookie)){
setcookie("StyleSheet",$value,time()+600000);/*expiresin10,000hours*/
return$_COOKIE["StyleSheet"];
}else{
return$_COOKIE["StyleSheet"];
}
if(isset($_GET['style'])){
header("Location:".$_SERVER['HTTP_REFERER']);
exit;
}
}
?>
index.php页面如下：
<!DOCTYPEhtmlPUBLIC"-//W3C//DTDXHTML1.0Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<htmlxmlns="http://www.w3.org/1999/xhtml">
<head>
<metahttp-equiv="Content-Type"content="text/html;charset=iso-8859-1"/>
<title>MyTestPage</title>
<?php
include("saveStyleSheet.php");
if(isset($_COOKIE["StyleSheet"])){
?>
<linkrel="stylesheet"type="text/css"href="stylesheets/<?phpechostyleSheet($_COOKIE["StyleSheet"]);?>"/>
<?php
}else{
?>
<linkrel="stylesheet"type="text/css"href="stylesheets/style.css"/>
<?php
}
?>
</head>
<body>
<ahref="saveStyleSheet.php?style=1">StyleSheet1</a><br/>
<ahref="saveStyleSheet.php?style=2">StyleSheet2</a><br/>
<ahref="saveStyleSheet.php?style=3">StyleSheet3</a><br/>
<ahref="saveStyleSheet.php">DefaultStyleSheet</a>
</body>
</html>
希望本文所述对大家的php程序设计有所帮助。
