How can PHP date functions be utilized to accurately calculate the days of a week based on a given date?

To accurately calculate the days of a week based on a given date in PHP, you can use the date() function along with the 'w' format character to get the numeric representation of the day of the week (0 for Sunday, 1 for Monday, etc.). Then, you can use this information to calculate the start and end dates of the week. 

$date = "2022-10-15"; // Given date
$dayOfWeek = date('w', strtotime($date)); // Get the numeric representation of the day of the week

// Calculate the start date of the week (Sunday)
$startDate = date('Y-m-d', strtotime($date . " -" . $dayOfWeek . " days"));

// Calculate the end date of the week (Saturday)
$endDate = date('Y-m-d', strtotime($startDate . " +6 days"));

echo "Start Date: " . $startDate . "\n";
echo "End Date: " . $endDate;
