Header ('Location: http://www.nowamagic.net ');
Exit;
}

// Check if wap
Function check_wap (){
// Check whether it is a wap proxy with high accuracy
If (stristr ($ _ SERVER ['http _ pass'], "wap ")){
Return true;
}
// Check whether the browser accepts WML.
Elseif (strpos (strtoupper ($ _ SERVER ['http _ ACCEPT ']), "VND. WAP. WML")> 0 ){
Return true;
}
// Check USER_AGENT
Elseif (preg_match ('/(blackberry | configuration \/cldc | hp-| htc _ | htc-| iemobile | kindle | midp | mmp | motorola | mobile | nokia | opera mini | opera | Googlebot-Mobile | YahooSeeker \/M1A1-R2D2 | android | iphone | ipod | mobi | palm | palmos | pocket | portalmmm | ppc; | smartphone | sonyericsson | sqh | spv | symbian | treo | up. browser | up. link | vodafone | windows ce | xda _)/I ', $ _ SERVER ['http _ USER_AGENT']) {
Return true;
}
Else {

The code is as follows:

Function is_mobile_request ()
{
$ _ SERVER ['all _ http'] = isset ($ _ SERVER ['all _ http'])? $ _ SERVER ['all _ http']: '';
$ Mobile_browser = '0 ';
If (preg_match ('/(up. browser | up. link | mmp | symbian | smartphone | midp | wap | phone | iphone | ipad | ipod | android | xoom)/I ', strtolower ($ _ SERVER ['http _ USER_AGENT '])
$ Mobile_browser ++;
If (isset ($ _ SERVER ['http _ ACCEPT ']) and (strpos (strtolower ($ _ SERVER ['http _ ACCEPT']), 'application/vnd.wap.xhtml + XML ')! = False ))
$ Mobile_browser ++;
If (isset ($ _ SERVER ['http _ X_WAP_PROFILE '])
$ Mobile_browser ++;
If (isset ($ _ SERVER ['http _ PROFILE '])
$ Mobile_browser ++;
$ Mobile_ua = strtolower (substr ($ _ SERVER ['http _ USER_AGENT '], 0, 4 ));
$ Mobile_agents = array (
'W3c ', 'ACS-', 'alav', 'alca', 'amodi', 'Audi', 'avany', 'benq', 'bird ', 'blac ',

);
If (in_array ($ mobile_ua, $ mobile_agents ))
$ Mobile_browser ++;
If (strpos (strtolower ($ _ SERVER ['all _ http']), 'operamini ')! = False)
$ Mobile_browser ++;
// Pre-final check to reset everything if the user is on Windows
If (strpos (strtolower ($ _ SERVER ['http _ USER_AGENT ']), 'windows ')! = False)
$ Mobile_browser = 0;
// But WP7 is also Windows, with a slightly different characteristic
