New calendar libraries make CodeIgniter multi-calendar capable with completely old code compatibility.
For developing international projects using CodeIgniter framework, beside language string support there is need of other calendars that is used on those countries specially in Asia.
There is a Multi_Calendar library in the heart of new calendar library. This class is a collection of functions and constants converted to PHP syntax from an already JS code mentions in PHP documentation, Calendar reference.
User can load it and use it to convert about 11 different calendars dates or check if it is Leap year in that calendar. This way users will have a complete calendar library for almost all existing calendar.
The old calendar library has been changed too. Now there will be Calendar_gregorian, Calendar_persian, ... classes that will implement the current calendar class for that particular calendar. The old one will call functions of extended classes and it will remain compatible with old codes.
It can make Codeigniter it richer without any much complexity or overhead in size,
Persian and Gregorian(no change from original calendar class) calendars have been prepared and others are in the way. CI_Calendar has been changed to call Gregorian(default) Persian, Hebrew, Arabic ... calendars. So this changes are completely compatible with old version of using Calendar (without any changes), just if anyone want to use other calendars it is possible not just by passing a "base_calendar" config parameter.
This way codeigniter may be the first framework to support multiple calendars (now it means truly a internationalization support).
The base JS codes are Public domain and new changes license will be GPL or it can be changed to fit in codeigniter license.
Here there is a libs and a sample controller to use them File:multi_calendar.zip
This file contains:
