$mobile_browser = '0';

if (preg_match('/(up.browser|up.link|mmp|symbian|smartphone|midp|wap|phone|android)/i', strtolower($_SERVER['HTTP_USER_AGENT']))) {
    $mobile_browser++;
}

if ((strpos(strtolower($_SERVER['HTTP_ACCEPT']),'application/vnd.wap.xhtml+xml') > 0) or ((isset($_SERVER['HTTP_X_WAP_PROFILE']) or isset($_SERVER['HTTP_PROFILE'])))) {
    $mobile_browser++;
}    

$mobile_ua = strtolower(substr($_SERVER['HTTP_USER_AGENT'], 0, 4));
$mobile_agents = array(
    'w3c ','acs-','alav','alca','amoi','audi','avan','benq','bird','blac',
    'blaz','brew','cell','cldc','cmd-','dang','doco','eric','hipt','inno',

    'wapr','webc','winw','winw','xda ','xda-');

if (in_array($mobile_ua,$mobile_agents)) {
    $mobile_browser++;
}

if (strpos(strtolower($_SERVER['ALL_HTTP']),'OperaMini') > 0) {
    $mobile_browser++;
}

if (strpos(strtolower($_SERVER['HTTP_USER_AGENT']),'windows') > 0) {
    $mobile_browser = 0;
}

if ($mobile_browser > 0) {
   // do something
