…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:
|
1 2 3 4 5 6 7 8 9 10 11 |
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(); |
