实例如下：

/** * 判断当前访问的用户是 PC端 还是 手机端 返回true 为手机端 false 为PC 端 * @return boolean */function isMobile(){   $useragent=isset($_SERVER["HTTP_USER_AGENT"]) ? $_SERVER["HTTP_USER_AGENT"] : "";   //echo $useragent;die;  $useragent_commentsblock=preg_match("|(.*?)|",$useragent,$matches)>0?$matches[0]:"";      function CheckSubstrs($substrs,$text){     foreach($substrs as $substr)       if(false!==strpos($text,$substr)){         return true;       }       return false;   }  $mobile_os_list=array("Google Wireless Transcoder","Windows CE","WindowsCE","Symbian","Android","armv6l","armv5","Mobile","CentOS","mowser","AvantGo","Opera Mobi","J2ME/MIDP","Smartphone","Go.Web","Palm","iPAQ");  $mobile_token_list=array("Profile/MIDP","Configuration/CLDC-","160×160","176×220","240×240","240×320","320×240","UP.Browser","UP.Link","SymbianOS","PalmOS","PocketPC","SonyEricsson","Nokia","BlackBerry","Vodafone","BenQ","Novarra-Vision","Iris","NetFront","HTC_","Xda_","SAMSUNG-SGH","Wapaka","DoCoMo","iPhone","iPod");   $found_mobile=CheckSubstrs($mobile_os_list,$useragent_commentsblock) ||        CheckSubstrs($mobile_token_list,$useragent);   if ($found_mobile){     return true;   }else{     return false;   } }
