如何使用PHP检测访问者的浏览器？

Question

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:

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?

Answer 1

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();
