What is the difference between the DATE and DATETIME data types in MySQL and how does it affect PHP usage?

The main difference between the DATE and DATETIME data types in MySQL is that DATE stores only the date without the time, while DATETIME stores both the date and time. This can affect PHP usage when retrieving and displaying the data, as DATE values will not include a time component and may need to be formatted differently compared to DATETIME values. 

// Example PHP code snippet to handle DATE and DATETIME values from MySQL

// Assuming $row is an associative array containing data fetched from MySQL
$dateValue = $row['date_column']; // Retrieve a DATE value
$datetimeValue = $row['datetime_column']; // Retrieve a DATETIME value

// Format DATE value
$formattedDate = date('Y-m-d', strtotime($dateValue));
echo "Date: ".$formattedDate;

// Format DATETIME value
$formattedDatetime = date('Y-m-d H:i:s', strtotime($datetimeValue));
echo "Datetime: ".$formattedDatetime;
