MCAL FunctionsMCAL stands for Modular Calendar Access Library. Libmcal is a C library for accessing calendars. It's written to be very modular, with pluggable drivers. MCAL is the calendar equivalent of the IMAP module for mailboxes. With mcal support, a calendar stream can be opened much like the mailbox stream with the IMAP support. Calendars can be local file stores, remote ICAP servers, or other formats that are supported by the mcal library. Calendar events can be pulled up, queried, and stored. There is also support for calendar triggers (alarms) and recurring events. With libmcal, central calendar servers can be accessed, removing the need for any specific database or local file programming. Most of the functions use an internal event structure that is unique for each stream. This alleviates the need to pass around large objects between functions. There are convenience functions for setting, initializing, and retrieving the event structure values.
Note:
This extension has been moved to the » PECL repository and is no longer bundled with PHP as of PHP 5.0.0.
Note:
PHP had an ICAP extension previously, but the original library and the PHP extension is not supported anymore. The suggested replacement is MCAL.
Note:
This extension is not available on Windows platforms. This extension requires the mcal library to be installed. Grab the latest version from » http://mcal.chek.com/ and compile and install it.
After you installed the mcal library, to get these functions to
work, you have to compile PHP
The constants below are defined by this extension, and will only be available when the extension has either been compiled into PHP or dynamically loaded at runtime.

MCAL is a great little package, but has changed quite a bit since the documentation has been updated. If you're having trouble stop by mcal.chek.com and pop a question onto the mcal users mailing list and we'll be happy to help you out.

Correction to previous extensive note: ANDing distinct bit values will always result in zero, so your weekly events won't ever be raised. You must use the bitwise-or operator (|) to combine several week days. mcal_event_set_recur_weekly takes an additional integer parameter "weekdays" which is basicly a binary mask created by bitwise ORing together integers representing the days of the week. Sunday = 1 Monday = 2 Tuesday = 4 Wednesday = 8 Thursday = 16 Friday = 32 Saturday = 64 So if I wanted the value needed to raise the event every "Monday, Wednesday, and Friday" I would do this: $weekdays = 2 | 8 | 32; jeff
As of 7/3/2001, libmcal can be built shared (libmcal.so), which should get rid of the linking problem with the MySQL driver. Check the latest version out of the repository if you're planning on building it this way.

After a thorough search of the web for documentation of how recurence works in MCAL, or even for documentation of the recurence function parameters, I found nothing. So, I gave up and dove into the MCAL source code for answers, and this is what I have found. Please keep in mind that this is all "As far as I can tell" information. First of all, I believe that mcal_list_events DOES return events that recur in the range being searched. The mcal_event_set_recur_* functions take in an mcal stream, and date for the event to stop recuring by (given by day, month, year), and an "interval". mcal_event_set_recur_weekly takes an additional integer parameter "weekdays" which is basicly a binary mask created by bitwise ANDing together integers representing the days of the week. Sunday = 1 Monday = 2 Tuesday = 4 Wednesday = 8 Thursday = 16 Friday = 32 Saturday = 64 So if I wanted the value that represented "Monday, Wednesday, and Friday" I would do this: $weekdays = 2 & 8 & 32; Here is how to interpret "interval" and "weekdays". For mcal_event_set_recur_daily: This event should recur every "interval" days. For mcal_event_set_recur_weekly: This event should recur on every day specified in "weekdays", and should do so every "interval" weeks. For mcal_event_set_recur_monthly_mday: This event should recur on the "interval" day of every month. For mcal_event_set_recur_monthly_wday: This event should recur every on every Xday of the Yth week of the month, every "interval" months. (Where Xday is a day of the week, e.g. Monday, Tuesday, etc. Note: This is the one I am the least sure about though it seems to be the logical assumption for how it should work based on the fact that there are two monthly functions and the other one's operation is intuitive.) For mcal_event_set_recur_yearly: This event should recur every "interval" years. |
