What PHP functions or methods can be used to manipulate and format dates to ensure accurate calculations in scenarios like the one described in the forum thread?

To ensure accurate date calculations in scenarios like the one described in the forum thread, PHP functions like strtotime(), date(), and DateTime class can be used to manipulate and format dates. By converting dates to Unix timestamps using strtotime(), performing calculations, and then converting them back to formatted dates using date() or DateTime class methods, accurate date calculations can be achieved. 

// Example code snippet to manipulate and format dates for accurate calculations

// Input dates
$date1 = "2022-01-15";
$date2 = "2022-02-20";

// Convert dates to Unix timestamps
$timestamp1 = strtotime($date1);
$timestamp2 = strtotime($date2);

// Calculate the difference in seconds
$diff_seconds = $timestamp2 - $timestamp1;

// Convert the difference to days
$diff_days = floor($diff_seconds / (60 * 60 * 24));

// Output the result
echo "The difference between $date1 and $date2 is $diff_days days.";
