How to Build a Calendar Table in PHP?

In PHP, by using the Date and DateTime Functions, we can build a dynamic Calendar Table based on user input.

Below are the approaches to Build a Calendar Table in PHP:

In this approach, we are using PHP's Date Functions like mktime() and date() to calculate and display a calendar table for a specified month and year entered by the user. The code dynamically generates the calendar based on the number of days in the month and the starting day of the week.

In this approach, we are using PHP's DateTime Object like new DateTime($dateString) to calculate the first day of the month and cal_days_in_month(CAL_GREGORIAN, $month, $year) to determine the number of days in the month. The code then generates a calendar table based on this information, displaying the days of the month
