With the help of JavaScript we can determine exact browser name and its version. The JavaScript object “navigator.userAgent” contains the complete information of a browser like CodeName, Name, Version etc. With the help of regular expressions we can extract the information that we need.
<!DOCTYPE html>
<html>
<head>
<script>
function detectBrowser(){
var N= navigator.appName;
var UA= navigator.userAgent;
var temp;
var browserVersion= UA.match(/(opera|chrome|safari|firefox|msie)\/?\s*(\.?\d+(\.\d+)*)/i);
if(browserVersion && (temp= UA.match(/version\/([\.\d]+)/i))!= null)
browserVersion[2]= temp[1];
browserVersion= browserVersion? [browserVersion[1], browserVersion[2]]: [N, navigator.appVersion,'-?'];
return browserVersion;
};
function browserCheck(){
alert(detectBrowser());
}
</script>
</head>
<body>
</br>
</br></br>
<button onclick="browserCheck();">Click here to check!</button>
</body>
</html>
Here we are determine exact browser name and its version with the help of PHP.
$browserAgent = $_SERVER['HTTP_USER_AGENT']; echo $browserAgent;
OR
You can also try this code
function GetBrowserName()
{
$GetBrowserNameUA=$_SERVER[‘HTTP_USER_AGENT’];
If (strpos(strtolower($GetBrowserNameUA), “safari/”) and strpos(strtolower($GetBrowserNameUA), “opr/”)) {
// OPERA
$GetBrowserNameBR=”Opera”;
} ElseIf (strpos(strtolower($GetBrowserNameUA), “safari/”) and strpos(strtolower($GetBrowserNameUA), “chrome/”)) {
// CHROME
$GetBrowserNameBR=”Chrome”;
} ElseIf (strpos(strtolower($GetBrowserNameUA), “msie”)) {
// INTERNET EXPLORER
$GetBrowserNameBR=”Internet Explorer”;
} ElseIf (strpos(strtolower($GetBrowserNameUA), “firefox/”)) {
// FIREFOX
$GetBrowserNameBR=”Firefox”;
} ElseIf (strpos(strtolower($GetBrowserNameUA), “safari/”) and strpos(strtolower($GetBrowserNameUA), “opr/”)==false and strpos(strtolower($GetBrowserNameUA), “chrome/”)==false) {
// SAFARI
$GetBrowserNameBR=”Safari”;
} Else {
// OUT OF DATA
$GetBrowserNameBR=”OUT OF DATA”;
};
return $GetBrowserNameBR;
}
echo GetBrowserName();
