How can the strtotime() function be utilized effectively in PHP for date calculations like determining the next Monday?

To determine the next Monday from a given date, you can use the strtotime() function in PHP along with the 'next Monday' keyword. This function converts a human-readable date/time string into a Unix timestamp, making it easy to perform date calculations. By adding the appropriate number of seconds to the current date, you can find the timestamp for the next Monday.

$current_date = strtotime('2022-12-01');
$next_monday = strtotime('next Monday', $current_date);

echo date('Y-m-d', $next_monday);
