A Class for Validating and Formatting Dates
by Tony MarstonTonyMarston.net
Summary
It is always useful to have a standard way of validating and formatting dates. Hopefully this tutorial has demonstrated how easily this can be done by using functions defined within a date class. It should now be a straightforward process for you to take this source code and customise it for your own purposes.
The full source code for this class can be viewed here.

About The Author:
I have been a software engineer, both designing and developing, since 1977. I have worked with a variety of 2nd, 3rd and 4th generation languages on a mixture of mainframes, mini- and micro-computers. I have worked with flat files, indexed files, hierarchical databases, network databases and relational databases. The user interfaces have included punched card, paper tape, teletype, block mode, CHUI, GUI and web. I have written code which has been procedural, model-driven, event-driven, component-based and object oriented. I have built software using the 1-tier, 2-tier, 3-tier and Model-View-Controller (MVC) architectures. After working with COBOL for 16 years I switched to UNIFACE in 1993, starting with version 5, then progressing through version 6 to version 7. In the middle of 2002 I decided to teach myself to develop web applications using PHP and MySQL.
