CSC 341: The Week beginning Sept. 18

• Homework:
  
  Write an HTML page that allows the user to enter his/her birthday (month and day) using drop-down selects and then hit a submit button. A responding PHP should display the day of the week of the user's birthday for the next 10 years. (Do not assume the user accesses the page in 2017.) What does your program do if the user enters Feb. 29th?
  
  Make a page or pages that use FILTER_VALIDATE_URL to determine if the user has entered a correctly formed URL.

  Lab: REGEX Validation
  Create a page with a form and some PHP to validate that form (they could be but don't have to be the same page). The user should enter the following data and you should write regular expressions (regex) to test their validity.
  
  • La Salle ID (exactly 7 digits)
  • La Salle usename -- two or more lowercase letters following by 0, 1, 2 or 3 digits (e.g. blum, smithj106, etc.)
  • La Salle Course -- three or four capital letters, possibly white space, and then three digits (CSC 341, CSIT 327, CSIT220, etc.)
  • La Salle Room Location -- four capital letters, possibly white space, and then two or three digits (OLNE 113, HOLR 53, LSBB179, etc.)
  
  As the data is being posted, you should apply a trim function (http://php.net/manual/en/function.trim.php) as well as a htmlspecialchars (http://php.net/manual/en/function.htmlspecialchars.php).
  
  You might also consider the function strip_tags (http://php.net/manual/en/function.strip-tags.php) if you don't want the tags but still follow it up with an htmlspecialchars.
