Detect Mobile Phone(or not), then what?

Post by ninethousandfeet »

hello,

i have read multiple posts online and articles related to making a site better for those viewing it via a mobile phone. i have this script to detect if it is a mobile phone or not (which seems to be a popular script in various forums... but i don't know what to do at the end of the script) i added

Code: Select all

header(location: mysite.com/mobile) } else { header(location:mysite.com)
but that produces this error: "Too many redirects occurred trying to open..."
any suggestions? basically, i don't know how to proceed when the detection script is finished..

Code: Select all

 
<?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',

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']),' ppc;')>0) {
    $mobile_browser++;
}
 
if (strpos(strtolower($_SERVER['HTTP_USER_AGENT']),'windows ce')>0) {
    $mobile_browser++;
}
else if (strpos(strtolower($_SERVER['HTTP_USER_AGENT']),'windows')>0) {
    $mobile_browser=0;
}
 
if (strpos(strtolower($_SERVER['HTTP_USER_AGENT']),'iemobile')>0) {
    $mobile_browser++;
}
 
if($mobile_browser>0) {
   // do something, yes mobile
   header("Location: Mobile_index.php");
}
else {
   // do something else NOT mobile
   header("Location: index.php");
}
?>
