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：

<&#63;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; 
  } 
}
