Here is the script with all your needs.

<?php
if ( strpos($_SERVER['HTTP_USER_AGENT'], 'Gecko') )
{
   if ( strpos($_SERVER['HTTP_USER_AGENT'], 'Netscape') )
   {
     $browser = 'Netscape (Gecko/Netscape)';
   }
   else if ( strpos($_SERVER['HTTP_USER_AGENT'], 'Firefox') )
   {
     $browser = 'Mozilla Firefox (Gecko/Firefox)';
   }
   else
   {
     $browser = 'Mozilla (Gecko/Mozilla)';
   }
}
else if ( strpos($_SERVER['HTTP_USER_AGENT'], 'MSIE') )
{
   if ( strpos($_SERVER['HTTP_USER_AGENT'], 'Opera') )
   {
     $browser = 'Opera (MSIE/Opera/Compatible)';
   }
   else
   {
     $browser = 'Internet Explorer (MSIE/Compatible)';
   }
}
else
{
   $browser = 'Others browsers';
}

if ($_SERVER['HTTP_X_FORWARD_FOR']) {
$ip = $_SERVER['HTTP_X_FORWARD_FOR'];
} else {
$ip = $_SERVER['REMOTE_ADDR'];
}

$hostname = gethostbyaddr($_SERVER['REMOTE_ADDR']);

echo "Hello Visitor, here is your Info:<br><br>";

echo "You are using: " . $browser . "<br>";

echo "Your IP is: " . $ip . "<br>";

echo "Your Hostname is: " . $hostname;

?>

Thank you very much mehdi I added you a reputation. Also I am looking for a free script with no link back which shows a beautiful Country flag of the visitors Also if there's any script to find the User's ISP details. It would be great if you help me again in these matters

 

Try looking at:
http://www.analysespider.com/ip2country/

hope its what you are finding.

 

I was looking for same but free, totally free

 

Have a look:
http://www.boastology.com/tools/ip2c.php

they are not providing the script, but give you a code to insert in your webpage.

 

I would use the following for IP, it tends to work better.

<?
$ip = (getenv(HTTP_X_FORWARDED_FOR)) ? getenv(HTTP_X_FORWARDED_FOR):getenv(REMOTE_ADDR);
echo $ip;
?>

PHP:
