Mobile Detect是检测移动设备（包括平板电脑）一个轻量级的PHP类。它使用的User-Agent字符串与特定的HTTP标头组合，以检测移动环境。

您可以考虑这个脚本是RESS（与服务器端组件响应网页设计）的一部分。通过阅读这些文章，你可以学到更多关于响应式的知识：

下面是Mobile Detect使用方法示例：

// Include and instantiate the class.
require_once \'Mobile_Detect.php\';
$detect = new Mobile_Detect;
 
// Any mobile device (phones or tablets).
if ( $detect->isMobile() ) {
 
}
 
// Any tablet device.
if( $detect->isTablet() ){
 
}
 
// Exclude tablets.
if( $detect->isMobile() && !$detect->isTablet() ){
 
}
 
// Check for a specific platform with the help of the magic methods:
if( $detect->isiOS() ){
 
}
 
if( $detect->isAndroidOS() ){
 
}
 
// Alternative method is() for checking specific properties.
// WARNING: this method is in BETA, some keyword properties will change in the future.
$detect->is(\'Chrome\')
$detect->is(\'iOS\')
$detect->is(\'UC Browser\')
// [...]
 
// Batch mode using setUserAgent():
$userAgents = array(

// [...]
);
foreach($userAgents as $userAgent){
 
  $detect->setUserAgent($userAgent);
  $isMobile = $detect->isMobile();
  $isTablet = $detect->isTablet();
  // Use the force however you want.
 
}
 
// Get the version() of components.
// WARNING: this method is in BETA, some keyword properties will change in the future.
$detect->version(\'iPad\'); // 4.3 (float)
$detect->version(\'iPhone\') // 3.1 (float)
