Question

Advice on PHP browser detection, specifically Palm

Asked by: smetterd

The following seems to work well... I would like to get expert opinion on if it's a good way to do it...


//If principal is using a Palm, then set it for presentation changes, etc.
$string    =  $_SERVER['HTTP_USER_AGENT'];
$substring = 'Palm';
$pos = 0;
$pos = strpos($string, $substring, $pos);
   if ($pos ==''){
   $isPalm="0";
   }
   else {
   $isPalm="1";
   }

This is a quick and easy way to detect mobile phones with PHP. Try this script that i use:

<?php
$mobile_browser = '0';

if(preg_match('/(up.browser|up.link|mmp|symbian|smartphone|midp|wap|phone|vodafone|o2|pocket|mobile|pda|psp)/i',strtolower($_SERVER['HTTP_USER_AGENT'])))
{
      $mobile_browser++;
}

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

$mobile_ua = strtolower(substr($_SERVER['HTTP_USER_AGENT'],0,4));

$mobile_agents = array('acs-','alav','alca','amoi','audi','aste','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','opwv','palm','pana','pant','pdxg','phil','play','pluc','port','prox','qtek','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($mobile_browser > 0)
{
      // is a mobile browser
}
else
{
      // is not a mobile browser
}
?>

It's well deserved. What a USEFUL script!

Hi Ellandrd,

Thanks for this super-useful reply! I hope you're still around and wouldn't mind answering a couple of follow-up newbie questions:

1. If I am using a CMS, where would I put the code? The CMS (Concrete5) delivers everything from a database to the index.php page.

2. What do I need to do to actually have it do the re-direct? I think this code just has placeholders...

if($mobile_browser > 0)
{
      // is a mobile browser
}
else
{
      // is not a mobile browser

Thanks so much!

Andrey
