/*
Extension to PHP iCalendar for supporting publishing from Apple iCal
Date: 11.12.2003
Author: Dietrich Ayala
Copyright 2003 Dietrich Ayala

Description:
This allows iCal to publish to your PHP iCalendar site *without* WebDAV support.
This helps with commercial hosts where WebDAV is not available.

Features:
- supports publishing and deleting calendars
- does not require WebDAV

Installation:
1. place this file in your PHP iCalendar calendars directory (or anywhere else)
2. configure path to PHP iCalendar config file (below)
3. make sure that PHP has write access to the calendars directory (or whatever you set $calendar_path to)
4. set up directory security on your calendars directory
5. turn on publishing in your PHP iCalendar config file by setting $phpicalendar_publishing to 1.

Usage (Apple iCal):
1. Open iCal, select a calendar for publishing
2. Select "Publish" from the "Calendar" menu
3. Configure to your liking, and set the URL to (eg): http://localhost/~dietricha/calendar/calendars/publish.php
4. Click the "Publish" button

Security:
The calendars directory should be configured to require authentication. This can be done via any methods
supported by your webserver. There is much documentation available on the web for doing per-directory
authentication for Apache. This protects any private calendar data, and prevents unauthorized users
from updating or deleting your calendar data.
There's also code below that forwards any GET requests to the PHP iCalendar front page.

Troubleshooting:
You can turn on logging by setting the PHPICALENDAR_LOG_PUBLISHING constant to 1 below.
This will write out a log file to the same directory as this script.
Don't forget to turn off logging when done!!

3. Configure to your liking, and set the URL to (eg): http://localhost/~dietricha/calendar/calendars/publish.php
4. Click the "Publish" button

Usage (Mozilla Calendar):
1. Your version of php and apache MUST support $_SERVER['PATH_INFO']
2. You must have supplied a username and password in your config.php
2. Create your calendar in Mozilla
3. Add something to it (it must not be empty)
4. Manually upload it to your calendars directory.
5. Make sure that the webserver can write to the calendar file.
(Mozilla will not save to the remote location without first downloading a copy
from the remote location)
6. Edit your calendar setup in mozilla
   Location http://example.com/path/to/publish.php/calendarname.ics
   calendarname.ics should be a unique filename and must end with .ics
7. Username (username from config.php)
8. Password (password from config.php)
9. Check "publish changes automatically"

Security:
The calendars directory should be configured to require authentication. This can be done via any methods
supported by your webserver. There is much documentation available on the web for doing per-directory
authentication for Apache. This protects any private calendar data, and prevents unauthorized users
