How can the use of arrays and loops in PHP help in determining the weekday and month based on a specific day of the year?

To determine the weekday and month based on a specific day of the year, we can use arrays to store the names of weekdays and months. By using loops to iterate through the days of the year, we can calculate the weekday and month based on the given day. 

<?php
// Array of weekdays and months
$weekdays = array("Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday");
$months = array("January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December");

// Input day of the year
$day_of_year = 150;

// Calculate weekday and month
$weekday_index = $day_of_year % 7;
$month_index = floor($day_of_year / 30);

// Output results
echo "Day $day_of_year is on a " . $weekdays[$weekday_index] . " in " . $months[$month_index];
?>
