<?php
// Sally has a Computer Science class on Tuesdays and Thursdays

if ( ($date % 7) == 0) {
	print "Today is Tuesday<br/>\n";	// a sample code - need

Your task for this question is to make the program behave as written in the comments. Note that the sample output in the above program is not what's required: you don't need to print out the days of the week, instead you need to say what classes Sally has on the day given as an input or whether it's a weekend.

Some hints:

  1. Use || to combine the conditions. For instance, Sally has a Computer Science class if it's Tuesday or Thursday.
  2. Upload your program to rynite. To test it, type in the path to it and add the input at the end of the URL, for instance ?input=17. Make sure to try your program with different inputs.
  3. If your program is not working, check it carefully. Make sure that all parentheses, brackets, and quotation marks are closed, check the semicolon at the end of each print statement, and make sure that you follow the right format for the if/else or if/elseif statement.
  4. If your program doesn't work and you can't find a mistake, please ask me.
  5. For those who weren't in the lab: When you are done, send me an e-mail with the file name.
