How can MySQL Date/Time functions be utilized to simplify Date/Time calculations in PHP?

When working with Date/Time calculations in PHP, utilizing MySQL Date/Time functions can simplify the process by offloading some of the heavy lifting to the database server. This can help improve performance and reduce the complexity of the PHP code needed to handle Date/Time operations. 

// Example of utilizing MySQL Date/Time functions in PHP
$startDate = '2022-01-01';
$endDate = '2022-01-31';

// Calculate the number of days between two dates using MySQL DATEDIFF function
$query = "SELECT DATEDIFF('$endDate', '$startDate') AS dayDifference";
$result = mysqli_query($connection, $query);
$row = mysqli_fetch_assoc($result);

$dayDifference = $row['dayDifference'];

echo "Number of days between $startDate and $endDate: $dayDifference";
