Let's say that right now you have a class defined as follows:
class Calendar {
var $month;
var $year;
... other class members...
function render() {
}
}
When you call Calendar::render(), it renders the calendar for the month
defined by $year and $month. To achieve what you want, you need to
modify Calendar::render() and pass it, let's say, an array of integers,
each signifying the day of the month that should be specially marked
(e.g., days on which posts were added to a blog). So you would have
something like this:
class Calendar {
var $month;
var $year;
... other class members...
function render($special = array()) {
$days = date('t', strtotime("{$this->year}-{$this->month}-01"));
// output the table heading...
// output blank cells before the first of the month, if any...
for ($i = 1; $i <= $days) {
if (in_array($i, $special)) {
// output a specially formatted cell
} else {
// output a "normal" cell
}
}
// output blank cells after the last of the month, if any...
}
}
