This is basic code to check ip, host and browser.

If you wanna to check ip, you can use global variable:

$_SERVER["REMOTE_ADDR"];

To check host, you can use also global variable:

$host=gethostbyaddr($ip)

And at the end to check browser:

$_SERVER["HTTP_USER_AGENT"];

If we integrate this variables we can create code like this:

<?php
$ip=$_SERVER["REMOTE_ADDR"];
$host=gethostbyaddr($ip);
$browser=$_SERVER["HTTP_USER_AGENT"];

echo '<center>


<span>Your IP:';
echo $ip;
echo '
Your host:';
echo $host;
echo '
Your browser:';
echo $browser;
echo '</span></center>';
?>

First three lines declarate new variables: ip, host, browser. Rest - echo code show result on the screen.
