Summary

In this chapter, you pulled together the PHP date-related functions you learned about earlier in the book to work within a basic calendar application display. You learned how to test the validity of an input date using checkdate(), and you worked through an example script that applied some of the tools you have learned. You also were shown one method for adding and viewing events within your calendar application.

You also were shown how to build a date-related class library, which can be used to automate some of the more tedious aspects of working with dates within HTML forms.
