How can I detect a visitor's browser using PHP?

Followed the steps presented on Beginner PHP Tutorial - How To Detect a Visitors Browser and got different result.

Run the following code:

<?php
  $browser = get_browser(null, true);
  echo $browser['browser'];
?>

Result on Google Chrome:

谷歌浏览器上的结果
Instead of displaying Chrome , the browser displayed Default Browser .

Files in my folder:

  • browscap.ini - C:\\xampp\\php\\extras
  • php.ini - clearly specified the path of browscap.ini as shown below;

[browscap]
; http://php.net/browscap
browscap="C:\\xampp\\php\\extras\\browscap.ini"

What should I do to get the correct type of browser to be displayed on the page?

You can use this function to detect your browser :

function getBrowser(){

$agent = $_SERVER['HTTP_USER_AGENT'];
$name = 'NA';


if (preg_match('/MSIE/i', $agent) && !preg_match('/Opera/i', $agent)) {
    $name = 'Internet Explorer';
} elseif (preg_match('/Firefox/i', $agent)) {
    $name = 'Mozilla Firefox';
} elseif (preg_match('/Chrome/i', $agent)) {
    $name = 'Google Chrome';
} elseif (preg_match('/Safari/i', $agent)) {
    $name = 'Apple Safari';
} elseif (preg_match('/Opera/i', $agent)) {
    $name = 'Opera';
} elseif (preg_match('/Netscape/i', $agent)) {
    $name = 'Netscape';
}


return $name;

}

echo getBrowser();

I do this:

echo $_SERVER['HTTP_USER_AGENT'];
$browser = get_browser();
print_r($browser);
