php实现通过cookie换肤的方法_php技巧

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：

<?php 
include("saveStyleSheet.php"); 
if(isset($_COOKIE["StyleSheet"])){ 
?> 
 " />
<?php 
}else{ 
?> 

<?php 
} 
?>
