Display Users Browser

Display Users Browsers

Here is a small function to detect a users browser, and display a browser icon, if you have any. If you don't have any icons, or just don't want to use the feature, you can of course turn it off.

Source Code:

PHP:

<?php

function defineUserAgent($browser, $icon = true) {

$browserIcons = array(

'Mozilla Firefox' => './firefox.png', // Mozilla Firefox Icon Location
'Internet Explorer' => './explorer.png', // Internet Explorer Icon location
'Opera' => './opera.png', // Opera Icon Locations
'Netscape' => './netscape.png' // Netscape Icon Location

);

$browserIndex = array(

'Mozilla Firefox' => '/(firebird|firefox|gecko)/i',
'Opera' => '/opera/i',
'Netscape' => '/(netscape|mozilla)/i',
'Safari' => '/safari/i',
'Internet Explorer' => '/\msie/i',
'SearchBot' => '/(nuhk|googlebot|yammybot|openbot|slurp/cat|msnbot|ia_archiver)/i',
'OmniWeb' => '/omniweb/i',
'Flock' => '/flock/i',
'Links' => '/links/i',
'cURL' => '/curl/i',
'Galeon' => '/galeon/i',
'Epiphany' => '/epiphany/i',
'Lynx' => '/lynx/i',
'Wget' => '/wget/i',
'Phoenix' => '/phoenix/i',
'iCab' => '/icab/i',
'Camino' => '/camino/i',
'SeaMonkey' => '/seamonkey/i',
'Konqueror' => '/konqueror/i',
'Chimera' => '/chimera/i',
'MyIE' => '/myie/i'

);


foreach($browserIndex as $browserName => $pattern) {

if(preg_match($pattern, $browser)) {

$browserIcon = '';
if ($browserIcons[$browserName]) {

$browserIcon = ($icon) ? '<img src="' . $browserIcons[$browserName] . '" border="0">&nbsp;' : $browserIcon;

}

return $browserIcon . $browserName;

}

}

}

$userAgent = $_SERVER['HTTP_USER_AGENT'];

$browser_with_icon = defineUserAgent($userAgent); // Browser name with a icon

$browser_without_icon = defineUserAgent($userAgent, false); // Browser name without a icon

echo 'You are running <b>' . $browser_with_icon . '</b><br /><br />';

echo 'You are running <b>' . $browser_without_icon . '</b>';

?>

Hope this helps you all.

Wow, nice post. Couldn't you also use call letters to find out if they are using a certain browser, then do something different.

Yes, it is possible to edit the code to instead of showing images, to show letters or numbers.
