You are given a php program that has a variable \$celsius for temperature in celsius:

<?php
\$celsius = -5.5;
?>
<html>
<title>
Celsius/Fahrenheit converter
</title>
<body>

<p>The current temperature is <? print \$celsius?>C. </p>
</body>
</html>
``````

1. Start jedit, copy/paste this code into a file temperature.php, save the file.
2. Using sftp, upload this file to rynite into your public_html (or its subdirectory).
3. Type in the URL of the file in your browser to make sure that it works as it should.
4. Add another variable \$fahrenheit to the program. This variable should compute the corresponding temperature in Fahrenheit according to the following formula:

Tf = (9/5)*Tc+32; Tc = temperature in degrees Celsius, Tf = temperature in degrees Fahrenheit.

Convert this formula into PHP, use the variable \$celsius for temperature in celsius.
5. Add another paragraph to the page to display the temperature in degrees Fahrenheit. Upload the file to rynite and make sure it works.
6. Change the value of the variable celsius, upload the file to rynite. Check that the temperature in Fahrenheit changed as well.

You are given the following code that you need to save in a file madlibs.php

Your task is to write a story that has in it a person, a place, and an object (at least two of these should be used more than once in the story). Use the php variables \$person, \$place, and \$object so that when the program is run, the values of these variables are displayed. After you add a sentence upload the file to rynite, make sure that the program works. Add another sentence, upload again. Continue until the story is completed. Change the values of the three variables, upload the file again, and make sure that the story has changed.

#### To submit

Just upload the two files to rynite.
