It
'
s
written
to
be
very
modular
,
with
plugable
drivers
.
There
is
also
support
for
calendar
triggers
(
alarms
)
and
reoccuring
events
.
With
libmcal
,
central
calendar
servers
can
be
accessed
and
used
,
removing
the
need
for
any
specific
database
or
local
file
programming
.
To
get
these
functions
to
work
,
you
have
to
compile
PHP
with
--with-mcal
.
That
requires
the
mcal
library
to
be
installed
.
The
following
constants
are
defined
when
using
the
MCAL
module
:
MCAL_SUNDAY
