foreach 3d array

[Daveyz1983]

for ($i=1; $i<=12; $i++) {
for ($j=2003; $j<= 2023; $j++) {
$year = $j;
$month = $i;
@ ($calendar[$year][$month] as $key => $temp) {
soomefunction();
}
}
}

some of the arrays might be empty, so the scripts actually returns an error

Parse error: parse error, unexpected T_FOREACH in c:\intranet\applyaleave.php on line 28

how do i solve this?

[drew010]

well, in that snippet $year and $month arent array so they cant be used in a foreach, also i dont know what the variable $calendar is.

[Daveyz1983]

$calendar is the 3d doman.

$month and $years are just values

the calender array are stored as [year][month][day]

so 15 january 2003 will be
$calendar[2003][1][15] = 1;

something like this

so now i need to loop through all the arrays to search for value.
