Default help: register_global=off, I can not get URL

I set register_global=off in php.ini file, and I found my codes as
below does not work:
================================================== =================
<html>

<body>
<?php
$myid=$_GET['myid'];
$db = mysql_connect("localhost", "root", "949701");
mysql_select_db("school",$db);

if ($myid) {
   $result = mysql_query("SELECT * FROM teacher WHERE id=$myid",$db);
   $myrow = mysql_fetch_array($result);
   printf("name: %s\n<br>", $myrow["name"]);
   printf("address: %s\n<br>", $myrow["address"]);
   printf("year: %s\n<br>", $myrow["year"]);
}
else
{
    $result = mysql_query("SELECT * FROM teacher",$db);
    if ($myrow = mysql_fetch_array($result))
    {
        do {
                printf("<a href=\"%s?$myid=%s\">%s %s</a><br>\n",$_SERVER['PHP_SELF'],
                $myrow["id"], $myrow["name"], $myrow["address"]);
            } while ($myrow = mysql_fetch_array($result));
    }
    else
    {
        echo "sorry no records!";
    }
}
?>
</body>
</html>
================================================== ==================
The error is as below:
Notice: Undefined index: myid in D:\Apache Group\Apache2\htdocs\tt.php on line 6

I don't know how to define the variable "myid" when register_global=off. and my intention in my above code is to
get the related record through "myid".

Thanks in advance!
