mcal_list_alarms — List alarms active at a given time


array mcal_list_alarms(MCALconnection, year, month, day, hour, min, sec);
int MCALconnection: An open MCAL connection
int year: The year of the search date
int month: The month of the search date
int day: The day of the search date
int hour: The hour of the search time
int min: The minute of the search time
int sec: The second of the search time


An array of events with active alarms


mcal_list_alarms() returns an array containg every event which has an alarm active during the given date and time. Alarms are considered active if the specified time is during the event and the event has an alarm set, or if it is alarm minutes before the event or less, where alarm is the alarm set for the event.


Until very recently (early May, 2001), searching for alarms was broken in libmcal's mstore driver. Any version of PHP with MCAL support will work, but you will need to have linked against a recent copy of libmcal.

Example 725. Listing active alarms

$calendar = "{/mstore}";
$MCALconnection = mcal_open($calendar, "username", "password");

// List all events with an alarm active right now
list($year, $month,
     $day, $hour,
     $min, $sec) = explode(":", date("Y:n:j:G:i"));

$events = mcal_list_alarms($MCALconnection, $year, $month,
                           $day, $hour, $min, $sec);

foreach ($events as $eventid) {
    echo "Event " . $eventid . " has an alarm active.<br />";
