How can PHP classes be utilized effectively in creating a dynamic calendar?

To create a dynamic calendar using PHP classes, we can define a Calendar class that handles the generation of the calendar grid, navigation between months, and highlighting of current day. By encapsulating the calendar logic within a class, we can easily reuse and customize the calendar across different parts of our application.

<?php

class Calendar {
    private $month;
    private $year;

    public function __construct($month, $year) {
        $this->month = $month;
        $this->year = $year;
    }

    public function generateCalendar() {
        // Calendar generation logic goes here
    }

    public function navigateMonth($direction) {
        // Navigation logic goes here
    }

    public function highlightCurrentDay() {
        // Highlighting current day logic goes here
    }
}

// Example usage
$calendar = new Calendar(9, 2022);
$calendar->generateCalendar();
$calendar->navigateMonth('next');
$calendar->highlightCurrentDay();

?>
