How can the Date function and Mktime function be utilized to determine the day of the week in PHP?

To determine the day of the week in PHP, you can use the Date function in conjunction with the Mktime function. By creating a Unix timestamp using Mktime for a specific date, and then using the Date function to format that timestamp to display the day of the week, you can easily determine the day of the week for any given date.

$date = mktime(0, 0, 0, 8, 12, 2022); // Create a Unix timestamp for August 12, 2022
$dayOfWeek = date("l", $date); // Format the timestamp to display the day of the week
echo "The day of the week for August 12, 2022 is: " . $dayOfWeek; // Output the day of the week
