Open Port checker Script problem

[ba55meister]

Hi

I'm trying to create PHP script that checks if the port is open. I've configured my router port forwarding for port no 23000 and I get a "success" result from www.canyouseeme.org

But when I upload my script on to my domain and run it i get an error message:

 

Warning: fsockopen() [function.fsockopen]: unable to connect to 90.192.247.56:23000 (Connection timed out) in /home/user109/public_html/test/pcheck.php on line 4

cant see

 

Please help

 

<?php
$ipnumber = $_SERVER[REMOTE_ADDR];
$portnumber = "23000";
$fp = fsockopen($ipnumber,$portnumber,$errnum,$errstr,10);
if(!$fp)
{
$result = "cant see";
} else {
$result = "success";
fclose($fp);
}
echo $result;
?>

I found this thread http://forum.utorrent.com/viewtopic.php?id=38371

the link to the script there shows my port 23000 as open but when I copy the script and upload it to my hosting i get the "closed" result. bah!

Any ideas? is it my PHP configuration on the server? or it Apache or what? it's doing my head in
