If you want to find if your user is using a mobile browser or not you can use this function :
| php: |
function checkmobile ($opp, $uap, $acp) {
$isMobile = false;
$op = strtolower($opp);
$ua = strtolower($uap);
$ac = strtolower($acp);
$ip = $ipp;
$isMobile = strpos($ac, 'application/vnd.wap.xhtml+xml') !== false
|| $op != ''
|| strpos($ua, 'sony') !== false
|| strpos($ua, 'symbian') !== false
|| strpos($ua, 'nokia') !== false
|| strpos($ua, 'samsung') !== false
|| strpos($ua, 'mobile') !== false
|| strpos($ua, 'windows ce') !== false
|| strpos($ua, 'epoc') !== false
|| strpos($ua, 'opera mini') !== false
|| strpos($ua, 'nitro') !== false
|| strpos($ua, 'j2me') !== false
|| strpos($ua, 'midp-') !== false
|| strpos($ua, 'cldc-') !== false
|| strpos($ua, 'netfront') !== false
|| strpos($ua, 'mot') !== false
|| strpos($ua, 'up.browser') !== false
|| strpos($ua, 'up.link') !== false
|| strpos($ua, 'audiovox') !== false
|| strpos($ua, 'blackberry') !== false
|| strpos($ua, 'ericsson,') !== false
|| strpos($ua, 'panasonic') !== false
|| strpos($ua, 'philips') !== false
|| strpos($ua, 'sanyo') !== false
|| strpos($ua, 'sharp') !== false
|| strpos($ua, 'sie-') !== false
|| strpos($ua, 'portalmmm') !== false
|| strpos($ua, 'blazer') !== false
|| strpos($ua, 'avantgo') !== false
|| strpos($ua, 'danger') !== false
|| strpos($ua, 'palm') !== false
|| strpos($ua, 'series60') !== false
|| strpos($ua, 'palmsource') !== false
|| strpos($ua, 'pocketpc') !== false
|| strpos($ua, 'smartphone') !== false
|| strpos($ua, 'rover') !== false
|| strpos($ua, 'ipaq') !== false
|| strpos($ua, 'au-mic,') !== false
|| strpos($ua, 'alcatel') !== false
|| strpos($ua, 'ericy') !== false
|| strpos($ua, 'up.link') !== false
|| strpos($ua, 'vodafone/') !== false
|| strpos($ua, 'wap1.') !== false
|| strpos($ua, 'wap2.') !== false;
return $isMobile;
}
?> |
and this is an example how I am using it .. you can use it to redirect to another page :
| php: | <?
$op = $_SERVER['HTTP_X_OPERAMINI_PHONE'];
$ua = $_SERVER['HTTP_USER_AGENT'];
$ac = $_SERVER['HTTP_ACCEPT'];
if(checkmobile($op, $ua, $ac)){
setcookie("environment", "mobile", time()+60*60*24*7);
setcookie("user_agent", $ua, time()+60*60*24*7);
}
else {
setcookie("environment", "desktop", time()+60*60*24*7);
setcookie("user_agent", $ua, time()+60*60*24*7);
}

This script was adapted from : http://www.russellbeattie.com/blog/mobile-browser-detection-in-php <- in his script you also can find how to detect for a Search Bot
Here is a script to detect the Operating system from the user agent : http://www.geekpedia.com/code47_Detect-operating-system-from-user-agent-string.html
Here is a list of all the recorded user agents : http://www.user-agents.org/ or the list in xml format : http://www.user-agents.org/allagents.xml
Here is a list (in case you need exect agent) of all the mobile devices agents : http://www.zytrax.com/tech/web/mobile_ids.html
Hope you find this info useful
