Finding IP address

Hi,

I have tried a few pieces of code to find and echo the IP adress in a page but have not had any success. Im sure its fairly simple but i cant do it!

Can someone please tell me how to do this sucessfully.

<?php
echo $_SERVER['REMOTE_ADDR'];
?>


or you can do this


<?php
$IP = $_SERVER['REMOTE_ADDR'];

echo $IP;
?>

That doesnt work, it just comes up blank.

Any ideas?

Does your webserver even support php?? lol

yes it does, im running several PHP scripts on it.

The following is the code i am using.

Your IP is: <?php echo $_SERVER['REMOTE_ADDR']; ?>It outputs "Your IP is: "

Can you send me your url?

Sure - http://andrewthomas.org.uk/ip/ip.php

<?php
echo "<font color=\"black\">$_SERVER['REMOTE_ADDR']</font>";
?>


Maybe it blends in, lol. I am sorry, I have not a clue. This happened to me ages ago and I don't know how I fixed it.

Ok, thanks for your help. If you find a solution please let me know otherwise no problems.

Thanks again!

unless that kind of thing has been somehow disabled by your host, I'm using <?php echo $_SERVER['REMOTE_ADDR']; ?> and it work's fine :p

Is there any other way of doing this or not?

$_SERVER array values are set by the server. If they're not set you should ask the admin why the server doesn't set them. Create a page with

<?php phpinfo(); ?>

in it and search for REMOTE_ADDR and to what it's set.

It would be extremley weird IWHT that $_SERVER variables be disabled...

Try

echo getenv('REMOTE_ADDR');

Cheers Nightfire :thumbsup: , it works!

Thanks a lot :)

Is there anyway to get the host name aswell, either from the PHP code or from the ip address?

Thanks

Yeah:


<?php
$hostname = gethostbyaddr(getenv('REMOTE_ADDR');

echo $hostname;
?>


should output the ISP host from the IP address ;)
