How to use php to determine the type of client

This article mainly introduces the method of PHP to determine whether the client is a PC or a mobile phone, which can be used by the website for statistics. Friends who need to know more can refer to it.

When collecting website user data statistics, we often need to obtain the user's browser type and operating system type. This article mainly introduces how to determine the client type based on PHP. Friends who need it can come and find out.

Method one:

Method two:

    // 找不到为flase,否则为true
    return stristr($_SERVER[&#39;HTTP_VIA&#39;], "wap") ? true : false;

  // 脑残法，判断手机发送的客户端标志,兼容性有待提高

  } 
  // 协议法，因为有可能不准确，放到最后判断
  if (isset ($_SERVER[&#39;HTTP_ACCEPT&#39;]))
  {

    {
      return true;
    } 
  } 
  return false;
} 
?>

Determine whether the mobile phone is IOS or Android

The code is as follows :

/**
 * 判断是否手机访问
 */
function is_mobile()
{
  static $is_mobile;
  if (isset($is_mobile)) return $is_mobile;
  if (empty($_SERVER['HTTP_USER_AGENT'])) {
    $is_mobile = false;
  } elseif (strpos($_SERVER['HTTP_USER_AGENT'], 'Mobile') !== false // many mobile devices (all iPhone, iPad, etc.)
    || strpos($_SERVER['HTTP_USER_AGENT'], 'Android') !== false
    || strpos($_SERVER['HTTP_USER_AGENT'], 'Silk/') !== false
    || strpos($_SERVER['HTTP_USER_AGENT'], 'Kindle') !== false
    || strpos($_SERVER['HTTP_USER_AGENT'], 'BlackBerry') !== false
    || strpos($_SERVER['HTTP_USER_AGENT'], 'Opera Mini') !== false
    || strpos($_SERVER['HTTP_USER_AGENT'], 'Opera Mobi') !== false
  ) {
    $is_mobile = true;
  } else {
    $is_mobile = false;
  }
  return $is_mobile;
}
