Okay. So it sounds like you have your file

#EXTINF:-1,Channel 1
rtmp://cdn1.domain.com/iptv/ch2?code=key
#EXTINF:-1,Channel 2
rtmp://cdn1.domain.com/iptv/ch3?code=key
#EXTINF:-1,Channel 3
rtmp://cdn1.domain.com/iptv/ch4?code=key

and when you load

/get.php?key=112233445566

You want the key in that file to be replaced. Is that correct?

If so try:

$string = file_get_contents('location');
echo nl2br(str_replace('code=key', 'code=' . $_GET['key'], $string));

A user could manipulate the content on your site with this approach so be careful with that. If key is not literal you will need to use a regex. If the case of that parameter/value can vary use str_ireplace.
