Browser detect code in PHP not detecting Opera

I found the code in PHP documentation. This seems to be a nice and simple code, it can detect google chrome, firefox, IE and safari however it cannot detect Opera.

OUTPUT in OPERA:
Your browser: Google Chrome 45.0.2454.93 on windows reports: 
Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/45.0.2454.93 Safari/537.36 OPR/32.0.1948.69

Need help in modifying this code so it can detect opera.

  <?php
    function getBrowser()
    {
        $u_agent = $_SERVER['HTTP_USER_AGENT'];
        $bname = 'Unknown';
        $platform = 'Unknown';
        $version= "";

        //First get the platform?
        if (preg_match('/linux/i', $u_agent)) {
            $platform = 'linux';
        }
        elseif (preg_match('/macintosh|mac os x/i', $u_agent)) {
            $platform = 'mac';
        }
        elseif (preg_match('/windows|win32/i', $u_agent)) {
            $platform = 'windows';
        }

        // Next get the name of the useragent yes seperately and for good reason
        if(preg_match('/MSIE/i',$u_agent) && !preg_match('/Opera/i',$u_agent))
        {
            $bname = 'Internet Explorer';
            $ub = "MSIE";
        }
        elseif(preg_match('/Trident/i',$u_agent))
        { // this condition is for IE11
            $bname = 'Internet Explorer';
            $ub = "rv";
        }
        elseif(preg_match('/Firefox/i',$u_agent))
        {
            $bname = 'Mozilla Firefox';
            $ub = "Firefox";
        }
        elseif(preg_match('/Chrome/i',$u_agent))
        {
            $bname = 'Google Chrome';
            $ub = "Chrome";
        }
        elseif(preg_match('/Safari/i',$u_agent))
        {
            $bname = 'Apple Safari';
            $ub = "Safari";
        }
        elseif(preg_match('/Opera/i',$u_agent))
        {
            $bname = 'Opera';
            $ub = "Opera";
        }
        elseif(preg_match('/Netscape/i',$u_agent))
        {
            $bname = 'Netscape';
            $ub = "Netscape";
        }

        // finally get the correct version number
        // Added "|:"
        $known = array('Version', $ub, 'other');
        $pattern = '#(?<browser>' . join('|', $known) .
         ')[/|: ]+(?<version>[0-9.|a-zA-Z.]*)#';
        if (!preg_match_all($pattern, $u_agent, $matches)) {
            // we have no matching number just continue
        }

        // see how many we have
        $i = count($matches['browser']);
        if ($i != 1) {
            //we will have two since we are not using 'other' argument yet
            //see if version is before or after the name
            if (strripos($u_agent,"Version") < strripos($u_agent,$ub)){
                $version= $matches['version'][0];
            }
            else {
                $version= $matches['version'][1];
            }
        }
        else {
            $version= $matches['version'][0];
        }

        // check if we have a number
        if ($version==null || $version=="") {$version="?";}

        return array(
            'userAgent' => $u_agent,
            'name'      => $bname,
            'version'   => $version,
            'platform'  => $platform,
            'pattern'    => $pattern
        );
    }

    // now try it
    $ua=getBrowser();
    $yourbrowser= "Your browser: " . $ua['name'] . " " . $ua['version'] . " on " .$ua['platform'] . " reports: <br >" . $ua['userAgent'];
    print_r($yourbrowser);
    ?>

well, in opera

first check opera then for Chrome as the $u_agent is showing Chrome/, Safari/ and OPR/ in the result of $u_agent. So check for Opera as soon as you done with internet explorer by changing the code suggested by @aabejero.

elseif(preg_match('/OPR/i',$u_agent))
        {
            $bname = 'Opera';
            $ub = "OPR";
        }

if you don't do this sometime in Opera it gives Google Chrome as Browser

it's working now after some changes...

I changed this part....

 elseif(preg_match('/Opera/i',$u_agent))
        {
            $bname = 'Opera';
            $ub = "Opera";
        }

to

 elseif(preg_match('/OPR/i',$u_agent))
        {
            $bname = 'Opera';
            $ub = "OPR";
        }

Just use the basic function given in documentation get_browser.

<?php
echo $_SERVER['HTTP_USER_AGENT'] . "\n\n";

$browser = get_browser(null, true);
print_r($browser);
?>

In order for this to work, your browscap configuration setting in php.ini must point to the correct location of the browscap.ini file on your system.

browscap.ini is not bundled with PHP, you can download it here
