php如何通过cookie切换网页风格？这篇文章主要介绍了php实现通过cookie换肤的方法，通过cookie存储用户选择信息实现换肤效果，希望对大家有所帮助。

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[&#39;style&#39;]){ 
    case 1: 
      $value = &#39;style1.css&#39;; 
    break; 
    case 2: 
      $value = &#39;style2.css&#39;; 
    break; 
    case 3: 
      $value = &#39;style3.css&#39;; 
    break; 
    default: 
      $value = &#39;style.css&#39;; 
    break; 
  } 
  // If the user views this page, without using 
  // style=... then set cookie to the default 
  if(!isset($_GET[&#39;style&#39;])){ 
    $value = &#39;style.css&#39;; 
  } 
  // If the new value doesn&#39;t equal the old value allow cookie change 
  if(isset($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[&#39;style&#39;])){ 
    header("Location: ".$_SERVER[&#39;HTTP_REFERER&#39;]); 
    exit; 
  } 
} 
?>
