Write a php program that allows user to choose the month and year. The user must select month and year from the form else it will display error message. The user can mark for a special day and they must enter the day, description and color for that special day. Finally, the user press the submit query button and the calendar will be generated various options the user selected.

Implement the following functions:

html.inc.php:

1. html_CalendarForm() - Generates the html form to prompt the user

2. html_Errors($errors) - Displays the user errors.

3. html_Calendar($data) - Displays the html calendar based on the data from getCalendarData()

calendar.inc.php:

1. getCalendarData($month, $year) - Generates a single array of data containing all the information for the calendar.

Hints:

A calendar is always a grid of 7x6 rows.

If you pass the months and the year as integers you can use mktime to generate the appropriate timestamp.

Below is the form

Please help me implement the above functions. It's urgent. Thanks in advance!
