<?php
   //error_reporting(E_ERROR | E_PARSE);

    $name=$_REQUEST['name'];
    $email=$_REQUEST['email'];
    $address=$_REQUEST['address'];
    $phone=$_REQUEST['phone'];

    $result=mysql_query("insert into customers values('','$name','$email','$address','$phone')");
    $customerid=mysql_insert_id();
    $date=date('Y-m-d');
    $result=mysql_query("insert into orders values('','$date','$customerid')");
    $orderid=mysql_insert_id();

    $max=count($_SESSION['cart']);
    for($i=0;$i<$max;$i++){

To remove session variables, use unset. To redirect use header('Location: '.$url); die();

I believe this is what she means.

unset($_SESSION['name']);
header('location: done.php');
die();
