A3 Write the missing code for parts (a) to (f) in the PHP script A3.php which processes the product ID and order quantity data passed in the query string.
Assume the following two GET requests are sent to the web server, the PHP script A3.php will store the productid value and qty value in a session file and then create a cookie to store the last received productid value.
http://127.0.0.1/A3.php?productid=P003&qty=10 http://127.0.0.1/A3.php?productid=P008&qty=2
If there is no query string in the GET request and the stored cookie is not expired, the PHP script A3.php will output the information as shown in Figure A3.

Create a new session file if it does not exist, otherwise open the existing session file.
[1 mark] Store the qty value in the session file using productid value as the index. [1 mark]
Create a cookie named lastid to store the productid value found in the query string.
echo “Product ID in your last transaction is {$_COOKIE[‘lastid’]}
“;
The cookie should expire after 2 hours.
Check if a cookie named lastid has been sent to the server.
Write a foreach loop to output all session data as shown in Figure A3. Delete all session data.
