PHP: class Sd_Yabd

…Yet Another Browser Detector
First I thought about calling this script ‹ExtrAgent›, then I thought, hey,
there’s a whole bunch of other browser detection scripts around, so actually
it’s just yet another browser detector!
I have just updated this code and replaced the old function with the new class Sd_Yabd. It takes part of my upcoming PHP framework «Sourdough» which will be released in april/may 2004.

This class should be capable to recognize all major browser/systems. Pass the agent string to extract_agent() and get the browser information by one of the follwing functions: getAgent(), getName(), getFullname(), getSystem(), getFullsystem(), isBot(), getVersion()

sample usage:


include_once('Sd_Yabd.class.php');
$YABD = new Sd_Yabd(); // if no agent string specified, get the current agent
$YABD-&gt;printInfo();
// parse another agent string...
$YABD-&gt;parse("Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322)");
$browserName = $YABD-&gt;getName(); // this should return 'IE'
$browserFull = $YABD-&gt;getFullname(); // this should return 'Internet Explorer'
$browserVer  = $YABD-&gt;getVersion(); // this should return 6.0
$YABD-&gt;printInfo();

include_once('Sd_Yabd.class.php');

$YABD = new Sd_Yabd(); // if no agent string specified, get the current agent

$YABD->printInfo();

// parse another agent string...

$YABD->parse("Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322)");

$browserName = $YABD->getName(); // this should return 'IE'

$browserFull = $YABD->getFullname(); // this should return 'Internet Explorer'

$browserVer = $YABD->getVersion(); // this should return 6.0

$YABD->printInfo();
