Question

I cant figure out why it wont write the client IP address to the file, everything else works.

<?php 
$myFile = "ips.txt";
$fh = fopen($myFile, 'a') or die("can't open file");
fwrite($fh, $_SERVER['REMOTE_HOST']);
fclose($fh);
echo $_SERVER['REMOTE_ADDR'];


?>

Thanks in advance.

Answer 1

Maybe fwrite($fh, $_SERVER['REMOTE_ADDR']); ?

Why do you think that if echo $_SERVER['REMOTE_ADDR']; works,
fwrite($fh, $_SERVER['REMOTE_HOST']); should too?

Try echo $_SERVER['REMOTE_HOST']; first and see if it outputs something.

My guess: just change _HOST to _ADDR in fwrite as I said in the beginning.
