PHP Unable to determine user's browser information - php

Question

I want to determine which user uses which browser when they visit to my website.
For this process i'am using $_SERVER['HTTP_USER_AGENT'] but when i try to print it while i'am using chrome i get this result(on localhost):
Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.1916.153 Safari/537.36
What can i do to fix that ? Any help would be appriciated

Answer 1

$_SERVER['HTTP_USER_AGENT']
This gives the information of the browser as you said.
Always keep in mind that HTTP_USER_AGENT can be easily spoofed by the user.
get_browser() gives the browser's capability.
you can also use the php class provided by Wolfcast
use like:
$browser = new BrowserDetection();
echo 'You are using ', $browser->getBrowser(), ' version ', $browser->getVersion();
if you really want to differentiate the browsers from the client-side you could use the javascript to find the browser and apply the changes through that based on different browser.
this is a code that i obtained from internet that exactly differentiate the browsers.
var isOpera = !!window.opera || navigator.userAgent.indexOf(' OPR/') >= 0;
var isFirefox = typeof InstallTrigger !== 'undefined'; // Firefox 1.0+
var isChrome = !!window.chrome && !isOpera; // Chrome 1+
if(isFirefox){
//do the change
} else if (isChrome){
//do the change
}
