User Agent String Decipher...

[henryrhenryr]

Hi

I am trying to write a function to decode / decipher the user agent string. I've got so far but I wondered if anyone knows any quick ways to do this or any useful resources to help me finish. I have tried searching to little avail.

Here's my present code:

[code=php]

function decipher_agent( $in) {
$out['string']=$in;
if ($l= strpos(' '.$in,'MSIE')) {
$out['browser']='IE';
$l=$l+5;
$f=$l+3;
$out['version']=substr(' '.$in,$l,$f);
}
elseif ($l= strpos(' '.$in,'Firefox' )) {
$out['browser']='FireFox';
if ($t= strpos(substr($ in,$l),'2.')) {
$out['version']='2';
}
elseif ($t= strpos(substr($ in,$l),'1.')) {
$out['version']='1';
}
}
if ($l= strpos(' '.$in,'Windows' )) {
$out['os']='Windows';
$t= substr($in,$l);
if (strpos(' '.$t,'6')) {
$out['version']='Vista';
}
elseif (strpos(' '.$t,'5')) {
$out['version']='XP';
}
elseif (strpos(' '.$t,'4')) {
$out['version']='2K';
}
else {
$out['version']=substr($t,8,11 );
}
}
elseif ($l= strpos(' '.$in,'Mac')) {
$out['os']='Mac';
if (strpos(' '.$in,'OS X')) {
$out['version']='OS X';
}
else {
$out['version']=null;
}
}
elseif ($l= strpos(' '.$in,'Linux')) {
$out['os']='Linux';
$out['version']=null;
}
else {
$out['os']='Unknown OS';
}
return $out;
}
[/code]

Not so pretty ;) Any pointers much appreciated.

Your code is already quite short in achieving this task.

But these may help a bit.
