Visitor Sniffer
This PHP Visitors Sniffer uses the HTTP Header sent from your browser, to detect the type and version of browser and platform. There are lots of other sniffers on the web, this one is very simple and effective. It hasn't been designed to detect all browser and operating system combinations. Feel free to modify it if you see a need, and please let us know of any bugs.
Many browsers allow user to change the User Agent string used to detect the browser.
There is no simple way to detect if the User Agent has been changed. Most developers no longer rely on User Agent sniffing, instead they use JavaScript object testing to test if the function they wish to use is supported by the browser.
Latest update version 1.4 added Mozilla Firefox to the list of detected browsers.
Visitor Sniffer can be used to customize web pages for different browsers or for
gathering statistics on web visitors.
To use the visitor sniffer on your php page:
include("sniffer.php");
$snif = new sniffer();
Then the variables can be accessed like:
$snif->browser
$snif->browservers
$snif->version
$snif->major
$snif->minor
$snif->platform
