Hello Friends,

There are plenty of browsers(Mozilla Firefox , Internet Explorer , Google Crome , Safari , Opera and many more) and Operating systems (Windows , Linux , Unix and many more) available in web world. It might be a case when you want to get browser/operating system details of visitors or users who came across your website built up with PHP and fill up a contact request form. Browser/Operating System details will help you to analyze the contact us request made by visitor or user. By looking at browser info & Operating system info,you have a brief idea about users before replying them.

If you want to track visitor's or user's browser details than you may use get_browser() PHP function which is a very easy to remember also. But here i am sharing a function from which you will get a filtered data(only useful details). Below is the function and answer of all those people who want to know "How to get Browser/Operating system details in PHP".

function check_browser()
{
      $browsers = "mozilla msie gecko firefox ";
      $browsers.= "konqueror safari netscape navigator ";
      $browsers.= "opera mosaic lynx amaya omniweb";
      $browsers = split(" ", $browsers);
      $userAgent = strtolower( $_SERVER['HTTP_USER_AGENT']);
      $l = strlen($userAgent);
      for ($i=0; $i
      {
            $browser = $browsers[$i];
            $n = stristr($userAgent, $browser);
            if(strlen($n)>0)
            {
                  $version = "";
                  $navigator = $browser;
                  $j=strpos($userAgent, $navigator)+$n+strlen($navigator)+1;
                  for (; $j<=$l; $j++)
                  {
                         $s = substr ($userAgent, $j, 1);
                         if(is_numeric($version.$s) )
                               $version .= $s;
                         else
                               break;
                  }
            }
       }
       if (strpos($userAgent, 'linux')) {
            $platform = 'linux';
       }
       else if (strpos($userAgent, 'macintosh') || strpos($userAgent, 'mac platform x')) {
            $platform = 'mac';
       }
       else if (strpos($userAgent, 'windows') || strpos($userAgent, 'win32')) {
            $platform = 'windows';
       }
       return array(
            "browser" => $navigator,
            "version" => $version,
            "platform" => $platform,
            "userAgent" => $userAgent);
 }

 $browserdata = check_browser();
 $browser_with_version = $browserdata['browser'].' '.$browserdata['version'];
 $operating_system = $browserdata['platform'];

You need to call simply check_browser() and you will get the specific data of browser details with version and operating system details. Comment below if you find any problem.
