What are some alternative approaches to using if statements in PHP to check for specific holidays within a time frame?

One alternative approach to using if statements in PHP to check for specific holidays within a time frame is to use the `in_array` function with an array of holiday dates. This allows for a more concise and efficient way to check if a given date falls within the holiday time frame.

// Array of holiday dates
$holidays = array('2022-01-01', '2022-02-14', '2022-12-25');

// Date to check
$dateToCheck = '2022-02-14';

// Check if the date falls within the holiday time frame
if (in_array($dateToCheck, $holidays)) {
    echo "This date is a holiday";
} else {
    echo "This date is not a holiday";
}
