how to search a multi-Dimensial array

[arianhojat]

hello, i was hoping to use in_array($searchForThis,$array[0]) to look at a multiD array's values like
$array[0][0]
$array[0][1]
$array[0][2]

i think maybe this would be easier if i used another structure and how to do it with that structure. bascially my structre looks like this

$array[12][1][2005]="<a href='blah.asp?meetingID=1'>meeting1 for today</a>";
$array[12][1][2005]="<a href='blah.asp?meetingID=2'>meeting2 for today</a>";
$array[12][4][2005]="<a href='blah.asp?meetingID=3'>meeting1 for today</a>";
$array[12][4][2005]="<a href='blah.asp?meetingID=4'>meeting2 for today</a>";
$array[12][4][2005]="<a href='blah.asp?meetingID=5'>meeting3 for today</a>";
$array[12][17][2005]="<a href='blah.asp?meetingID=6'>meeting1 for today</a>";

and i loop through creating my calender for the month, if that day (the 28th pretend) is same as current day i output the all the info for the day into the table cell. i only really need i guess $array[$dayNumber] so is this a hash map?

It would seem to make more sense to nest your arrays in a more useful order; $array[$year][$month][$day] would seem to make the most sense. Then all the days for a particular month are in one array (e.g, $array[2005][1]), all the months for a particular year are in one array ($array[2005]), and so on.
