How do you get information from a form that is submitted using the "get" method?

Documentation and Google are your friends.

assume: http://xxx.xxx.xxx.xxx/proc.php?ref=12345

proc.php
<?php
$REMOTE_ADDR = $_SERVER['REMOTE_ADDR'];

$RECNO = $_SERVER['QUERY_STRING'];
$RECNO = `echo $RECNO |cut -d"=" -f2`;
$RECNO = rtrim($RECNO);

thanks for the solution
