#!/usr/bin/php -q
<?
$host=localhost;
$port=129;
system(´telnet $host $port´);
?>

You don't want to be running telnet through system() unless you use 'telnet < mysession.txt', because you can no longer write to the process, i.e. to enter a username or password. You would need [man]popen/man if you only need to write to telnet, or [man]proc_open/man if you need to read and write to the subprocess. Be aware that not everything will work in a pipe like this - some programs need a proper console (ssh for example).
