Where to place this code.

[Xtrigit]

Hello, everyone!

I would like to redirect mobile(iPhone) users to the mobile version of my site.

Here is what I found but I'm not sure where I should paste the code.

To get started all you have to do is place the following code in the stop of your php page. If your loading an application you can post this below your application just don?t output any data before the code is executed.

PHP Code:

<php
$mobile_browser = '0';if(preg_match('/(up.browser|up.link|mmp|symbian|smartphone|midp|wap|phone)/i',
strtolower($_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',
'ipaq','java','jigs','kddi','keji','leno','lg-c','lg-d','lg-g','lge-',
'maui','maxo','midp','mits','mmef','mobi','mot-','moto','mwbp','nec-',
'newt','noki','oper','palm','pana','pant','phil','play','port','prox',
'qwap','sage','sams','sany','sch-','sec-','send','seri','sgh-','shar',
'sie-','siem','smal','smar','sony','sph-','symb','t-mo','teli','tim-',
'tosh','tsm-','upg1','upsi','vk-v','voda','wap-','wapa','wapi','wapp',
'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;
}

//change this to your mobile friendly page
if($mobile_browser>0){
header( "Location: http://www.yourwebsite.com/mobile/" ) ;
} else {
// do something else
}

$ua = $HTTP_USER_AGENT;
if (stristr($ua, "Windows CE") or stristr($ua, "AvantGo") or stristr($ua,
"Mazingo") or stristr($ua, "Mobile") or stristr($ua, "T68") or stristr($ua,
"Syncalot") or stristr($ua, "Blazer") or stristr($ua, "NetFront"))
{
$DEVICE_TYPE="MOBILE";
}

if (isset($DEVICE_TYPE) and $DEVICE_TYPE=="MOBILE")
{
//change this to your mobile friendly page
header( "Location: http://www.yourwebsite.com/mobile/" ) ;
exit;
}

?> 


I want this to work, especially for iPhone and Android users.

Thanks!
