Hey PHP masters,

I just started on php not too long ago. I was wondering is there a way to detect which browser the user is using with PHP?

Thanks.

Simply, by using

<?php 

$browser =  $_SERVER["HTTP_USER_AGENT"]; 

echo 'Your Browser is: '. $browser;

?>

Hey Chaos King, look a little closer at your code, you'll notice that we don't usually name a variable that shows the browser "ip"
And we also don't say, Your ip is firefox, yip

My bad, was reading two topics at the same time. Kinda got both the requests mixed up.

My apologies.

Umm i found this on php.net the other day and it works a treat

$browser = array (
   "MSIE",			// parent
   "OPERA",
   "MOZILLA",		// parent
   "NETSCAPE",
   "FIREFOX",
   "SAFARI"
);

$info[browser] = "OTHER";

foreach ($browser as $parent) {
   $s = strpos(strtoupper($_SERVER['HTTP_USER_AGENT']), $parent);
   $f = $s + strlen($parent);
   $version = substr($_SERVER['HTTP_USER_AGENT'], $f, 5);
   $version = preg_replace('/[^0-9,.]/','',$version);
  
   if (strpos(strtoupper($_SERVER['HTTP_USER_AGENT']), $parent)) {
   $info[browser] = $parent;
   $info[version] = $version;
   }
}
if ($info[browser] == "MOZILLA") {
$info[browser] = "FIREFOX";
}

echo $info[browser];
