To my surprise I found that none of the get_browser alternatives output the correct name / version
combination that I was looking for using Opera or Chrome. They either give the wrong name eg Safari
when in fact it should be Chrome and if the ua string includes a version number as with the latest
versions of Chrome and Opera the wrong number is reported. So I took bits and pieces from the
various examples and combined them and added a check for version.
<?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';
$ub = "MSIE";
}
elseif(preg_match('/Firefox/i',$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
$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);
?>
