如果我们要判断访问网站的是手机用户还是PC用户我们只要获取用户的HTTP_USER_AGENT即可，我先介绍了一个通用的Mobile_Detect，后面两个例子是自己写的希望对各位有帮助。
php代码
| 代码如下 |
复制代码 |
|
//使用实例
include 'Mobile_Detect.php';
$detect = new Mobile_Detect();
// Check for any mobile device.
if ($detect->isMobile())
// Check for any tablet.
if($detect->isTablet())
// Check for any mobile device, excluding tablets.
if ($detect->isMobile() && !$detect->isTablet())
if ($detect->isMobile() && !$detect->isTablet())
// Alternative to $detect->isAndroidOS()
$detect->is('AndroidOS');
// Batch usage
foreach($userAgents as $userAgent){
$detect->setUserAgent($userAgent);
$isMobile = $detect->isMobile();
}
// Version check.
$detect->version('iPad'); // 4.3 (float)

{
$Loaction = 'wap/';
if (!empty($Loaction))
{
ecs_header("Location: $Loactionn");
exit;
}
}
/**

**/
function ecs_header($string, $replace = true, $http_response_code = 0)
{
if (strpos($string, '../upgrade/index.php') === 0)
{
echo '';
}
$string = str_replace(array("r", "n"), array('', ''), $string);
if (preg_match('/^s*location:/is', $string))
{
@header($string . "n", $replace);
exit();
}
if (emptyempty($http_response_code) || PHP_VERSION < '4.3')
{
@header($string, $replace);
}
else www.111cn.net
{
@header($string, $replace, $http_response_code);
