How can developers use the Parameter pattern to define custom date formats in PHP?

Developers can use the Parameter pattern to define custom date formats in PHP by creating a function that accepts a date format string as a parameter. This allows developers to easily specify different date formats without having to modify the function itself.

php

function formatDate($date, $format) {
    return date($format, strtotime($date));
}

// Example of using the function with custom date formats
echo formatDate('2022-01-01', 'Y-m-d'); // Output: 2022-01-01
echo formatDate('2022-01-01', 'F j, Y'); // Output: January 1, 2022
