移动设备（手机和平板）环境检测的 PHP 类库Mobile_Detect.php

Mobile Detect 是一个轻量级的开源移动设备（手机和平板）检测的 PHP Class，它使用 User-Agent 中的字符串，并结合 HTTP Header，来检测移动设备环境
这个设备检测的 PHP 类库最强大的地方是，它有一个非常完整的库，可以检测出所用的设备类型（包括操作类型，以及手机品牌等都能检测）和浏览器的详细信息。

Mobile_Detect 简单使用实例

// 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():
$userAgents = array(
'Mozilla/5.0 (Linux; Android 4.0.4; Desire HD Build/IMM76D) AppleWebKit/535.19 (KHTML, like Gecko) Chrome/18.0.1025.166 Mobile Safari/535.19',
'BlackBerry7100i/4.1.0 Profile/MIDP-2.0 Configuration/CLDC-1.1 VendorID/103',
// [...]
);
foreach($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)
$detect->version('Android'); // 2.1 (float)
$detect->version('Opera Mini'); // 5.0 (float)
