This document outlines a web programming activity that teaches functions in PHP. It has three tasks: 1) Create functions to wrap a string in red font tags and convert a number to a month name using an array. 2) Create the opposite function to convert a month name to a number. 3) Write explanations of the PHP code. The learning objectives are to understand how to define functions in PHP using the function keyword, include arguments, and return values.

Task 1:
• Create a PHP program with the following requirements
• Create a function named RedFont
– RedFont should accept a string, and return a string wrapped in <font
color=”red”></font>
• Create a function named NumberToMonth
– NumberToMonth should accept one argument, $number, and return the
name of the month
– So given the number 1, the program will return “January”
– Use an array to store month names
Write another function called MonthToNumber that does the opposite (given a Month
name, it returns a Number)
