How can PHP automatically insert the current date into a date calculation script for comparison?

To automatically insert the current date into a date calculation script for comparison, you can use the PHP `date()` function to get the current date in the desired format. You can then use this current date in your date comparison script to compare it with other dates.

$currentDate = date('Y-m-d'); // Get the current date in 'YYYY-MM-DD' format
$otherDate = '2022-12-31'; // Example date to compare with

if ($currentDate < $otherDate) {
    echo "Current date is before $otherDate";
} elseif ($currentDate > $otherDate) {
    echo "Current date is after $otherDate";
} else {
    echo "Current date is equal to $otherDate";
}
