Example one (recommended):

<?PHPHeader("Content-type:text/html;charset=utf-8");functionIsMobile () {$useragent=isset($_server[' Http_user_agent ']) ?$_server[' Http_user_agent ']: '; $useragent _commentsblock=Preg_match(' |\ (. *?\) | ',$useragent,$matches) >0?$matches[0]: '; functionChecksubstrs ($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-', ' 160x160 ', ' 176x220 ', ' 240x240 ', ' 240x320 ', ' the ' + ', ' up '.
