How can the use of arrays in PHP improve the efficiency of date calculations and manipulations?

Using arrays in PHP can improve the efficiency of date calculations and manipulations by allowing for easy storage and retrieval of date-related data. For example, you can store days of the week or months of the year in an array and easily access them when needed. This can streamline your code and make date calculations more readable and maintainable. 

// Example of using arrays for date calculations and manipulations

// Define an array of days of the week
$daysOfWeek = ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday'];

// Get the current day of the week
$currentDay = date('w');
echo 'Today is ' . $daysOfWeek[$currentDay];

// Define an array of months of the year
$monthsOfYear = ['January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December'];

// Get the current month
$currentMonth = date('n');
echo 'It is currently ' . $monthsOfYear[$currentMonth - 1];
