Show OS

patracy

Any idea on how to show a users OS and verision through PHP?

Hi,

you might be able to extract that info from

$_SERVER["HTTP_USER_AGENT"]

But you can't trust on that info in all cases.

I must admit I'm new to PHP. I've only used a few pre made scripts. How would I go about pulling the OS from that?

Hmmm ... I thought a little bit about my last post ... can't do it like that.

Not all browsers post that info in the same way.

Check out get_browser.

The downside is that you might need to install a browscap.ini file and change the php configuration.

Some ISPs have the browscap file installed. There's a link in the manual to a page where you can download a browscap.ini.

I think there's no easier solution than the above.

I know this is kinda silly. But I thought I've seen something that in did what I'm asking for. I saw it once in someone's sig. it was a simple image that looked like a sign. It displayed IP, OS, and browser. Was that in PHP?

Don't know ... but you can do this with PHP.

What tsinka said.

Here's a simple example creating a PNG image:

First, download the browscap.ini for PHP users here

Copy the file to a directory (web server needs read access to that directory)

Then edit php.ini and change the browscap = .....

line so that it contains the full path to the browscap file.

Then restart the web server.

<?php
$objBrowser = get_browser();
//print_r($objBrowser);
//exit;

$platform    = $objBrowser->platform;
$browser     = $objBrowser->browser;
$version     = $objBrowser->version;
$browser_string = "$browser, Ver. $version on $platform";
$ip          = $_SERVER['REMOTE_ADDR'];
$remote_host = gethostbyaddr($ip);
$decid = urldecode($_REQUEST['id'].$_REQUEST['key']);
header("Content-type: image/png");
$img = imagecreatetruecolor(200, 44);
$white = imagecolorallocate($img, 255, 255, 255);
$grey  = imagecolorallocate($img, 178, 178, 178);
imagefill($img, 0, 0, $grey);
imagestring($img, 3, 6, 3, $browser_string, $white);
imagestring($img, 3, 6, 15, "IP: $ip", $white);
imagestring($img, 3, 6, 27, "ISP: $remote_host", $white);
imagepng($img, '', 75);
imagedestroy($img);
?>

Browse the PHP manual a little bit to get an idea about how to do something like this using an existing image instead of creating an empty image.
