What best practices should be followed when retrieving and processing date and time data from a MySQL database using PHP?

When retrieving and processing date and time data from a MySQL database using PHP, it is important to ensure that the data is properly formatted and handled to avoid any issues with time zones or date formats. One best practice is to use PHP's date and time functions to manipulate the data as needed.

// Retrieve date and time data from MySQL database
$query = "SELECT * FROM table_name";
$result = mysqli_query($connection, $query);

while ($row = mysqli_fetch_assoc($result)) {
    // Process date and time data
    $date = date('Y-m-d', strtotime($row['date_column']));
    $time = date('H:i:s', strtotime($row['time_column']));
    
    // Use the processed date and time data as needed
    echo "Date: $date, Time: $time";
}
