Once again i get put in some easy and tiresome web development class here at my university. I have to make a web page.... 5 pages, galary, submit form, mailto and href...blah blah blah. I really want to wow the teacher, and somthing that i tought would  be nice would be the option for mobile access and a secure line (https). I have the php server side down, but i have no clue how to impliment browser detection...? Im faily sure it is done through java. Anyone have any good lituratue for me? Hopfully somthing a little more idiot proff than this >> http://jibbering.com...t-browser/#bdFD


Thanks. Btw, my knowledge in java is trivial on a good day. C++ im intermediate and html im an advance user. Thanks everyone.

You may have more luck doing it with JavaScript. Everyone seems to be using jQuery nowadays:




Recommended practice is, include jQuery from Google since most browsers have already cached it. Google supports/encourages this. Of course, a JS source include from a non-HTTPS source makes your HTTPS-served page less secure.


If you want a canned UI to work with, take a look at Twitter Bootstrap. That may be considered cheating for your particular assignment, though!

User agent string is probably the quickest way out the door. No add-ons or plugins or runtime environments. Just capture User-Agent using your server- or client-side scripting language of choice, and roll with it. Easy. :shuriken:

Howdy. Bitviper is correct. I half-stole this when I wrote it for my site , but if you'd like to see an example of how the http user-agent string can be used, here you go!


        $address = ($_SERVER['REMOTE_ADDR']);
        $useragent = strtolower($_SERVER['HTTP_USER_AGENT']);
        echo '<span class="phptext">Your external IP address is </span>';
        echo '<span class="phptext">', $address, '</span>';
        echo '<br>';
        //The OS detection script used here was taken from geekpedia.com
        //It is sightly modified for my purposes.
        //The original code was by Andrew Pociu, and then modified by Kevin F.
        /*It can be found here:
         * http://www.geekpedia.com/code47_Detect-operating-system-from-user-agent-string.html
        $osList = array
'Windows 8' => 'windows nt 6.2',           
'Windows 7' => 'windows nt 6.1',
'Windows Vista' => 'windows nt 6.0',
'Windows Server 2003' => 'windows nt 5.2',

foreach($osList as $os=>$match)
        if (preg_match('/' . $match . '/i', $useragent))
        $os = "Not automatically detected.<br>$useragent";

echo '<span class="phptext">Your Operating System is </span>';
echo <<<HEYHO
<span class="phptext">$os</span>;
echo '<br>';

//I liked that code so much. I decided to make a browser checker from it.
        $browlist = array

If you'd like to see the end result check out www.thefunkspace.com, but be warned, I'm terribad at web design, so it looks horrendous. Also I don't have any good content on the site yet whatsoever. It's going to be remade with wordpress or drupal or something like that, and then it'll get some content.
