Description: Contains a core class with no visual interface for use by you in your scripts AND a HTML interface class that will use the core class to display a one month calender with drop down month & year selector, next/previous month buttons, dates displayed are clickable and highlightable.
Currently it doesn’t look so great in netscape so I would appreciate any assistance with that.
<?php /* This an extension to the class I wrote, v 2.5.1 written by: David Hernandez Sanz ([email protected]) http://www.dhs.sitio.net/ This class is intended to be an extension, so make sure you download 2.5.1 first.
