Quicker / more effective moblie device detection script

Hi,

Not sure whether I should have posted this in the PHP forum or not, but thought I would try here first.

What I want to do it detect whether a user is on a PDA / phone or on a web browser to browse HTML pages. I have been playing around with some scripts but would like to have comments on a more effective way. I was thinking of additional stuff if it was a WAP browser, but just going for the (x)html first

PHP Code:


		
			
<?php

$browser = file('/path/browser.txt');

$match = '';

foreach ($browser as $line_num => $line) {

$match .= strstr(strtoupper($_SERVER['HTTP_USER_AGENT']), strtoupper($line)) ? TRUE : FALSE;        

}

echo $match == TRUE ? 'PDS or phone' : 'proper browser';

Basically it loops though a text file and if it returns true at all, it prints proper browser. So is there a better way?

I have attached teh browser list text that the script it reading. I have also included the current script that I have running to redirect to a wap site, but doesn't seem to work too well, so any comments on that much appreciated.

Thanks in advance..

Hi Jamie,

Your live index is from the same script I used on some of our wap sites, it seemed to do the trick most of the time but I modded ours to include more user agents then the default came with. Having more agents makes it more stable but I dumped it in the end.

PHP Code:


		
			
// check to see http_accept is wml

if(strpos(strtoupper($HTTP_ACCEPT),"VND.WAP.WML") > 0) {



$br = "WML";

}else{



// check to see if browser is recognised as a mobile or wap emulator

$browser=strtolower(substr(trim($HTTP_USER_AGENT),0,4));



// run if's against user agent

if($browser=="noki" || $browser=="sony" || $browser=="sec-" || $browser=="siem" ||

$browser=="sie-" || $browser=="pana" || $browser=="maxo" || $browser=="shar" ||

$browser=="eric" || $browser=="lge-" || $browser=="sams" || $browser=="wapI" ||

$browser=="mc21" || $browser=="aur " || $browser=="r380" || $browser=="qco7" ||

$browser=="up.B" || $browser=="winw" || $browser=="upg1" || $browser=="upsi" ||

$browser=="qwap" || $browser=="tsm-" || $browser=="jigs" || $browser=="java" ||

$browser=="alca" || $browser=="mits" || $browser=="moto" || $browser=="mot-" ||

$browser=="sage" || $browser=="webc" || $browser=="my s" || $browser=="wap j" ||

$browser=="fetc" || $browser=="alav" || $browser=="wapa"){

$br = "WML";

}else{

$br = "HTML";

}

}



//  manage output to reflect user agent

if($br == "WML") {



// user is mobile based echo wml

// check for xhtml?



}else{



// user is on a pc echo html



}

This list shows a load of user agents that have been by one of our wap sites if that helps. It should download as an Excel file but I just made it on a Mac without Office so if it's buggy let me know and I'll try to sort it.

In fact thinking about that list makes me realise how out of date that code snippet is, If I was still using it I'd prolly butcher it to eregi up.link as a match and add the other agents too in the hope it makes it more stable.

Hi Andy,
Thanks for the info.
I have actually modded my script a bit (now at work so no access to it).
Will play around some more when I get home.

Hi - took me a while to work out what you meant by eregi the Up.link but i've got it after looking at your browser string list - quick question though - what is the significance of the Up.link?

appreciate your help
