[PHP] Help with problem

[iUnknown]

Hello,

This is part of my PHP code:

<?php
if($port != !$port)
{
    $port = $_POST['port'];
    $handle = fopen('/home/XXXXXXXXXXX/public_html/players/'. $port .'.asx', "x+");
    $line1 = '<ASX version="3.0">'
    $line2 = '<title>Radio</title>'
    $line3 = '<entry>'
    $line4 = '    <title>Radio</title>'
    $line5 = '    <author>Tech-Hosts.co.uk</author>'
    $line6 = '    <ref href="http://shoutcasts.tech-hosts.com:'. $port .'/"/>'
    $line7 = '</entry>'
    $line8 = '</ASX>'
    
    fwrite($handle, $line1."\n")
    fwrite($handle, $line2."\n")
    fwrite($handle, $line3."\n")
    fwrite($handle, $line4."\n")
    fwrite($handle, $line5."\n")
    fwrite($handle, $line6."\n")
    fwrite($handle, $line7."\n")
    fwrite($handle, $line8."\n")
    fclose($handle);

I get this error when simply opening the document ($port is nothing/not defined).

Parse error: syntax error, unexpected T_VARIABLE in /home/XXXXXXXX/public_html/playercode.php on line 45

Line 45 is:

    $line2 = '<title>Radio</title>'

I'm not very good at PHP, I just pick things up as I go along and I've never spent time learning it. I'm trying to code a simple PHP script so I knew I'd need some real help along the way.

+rep to the first person to give a correct solution.

Thanks.

Haha thanks, +rep. One last thing, my bit at the top isn't working properly:

if($port != !$port)
{

It's doing that code even if $port isn't defined. Is there any other way to do this? I want it so when they post a form on that page it does the code below that, but if they haven't then I just want it to ignore that section (don't want to use else, just one if will do).

+rep to the person who can give me a correct solution fastest for that. Thanks.
