What are some best practices for storing and manipulating datetime values in PHP and MySQL databases?

When storing and manipulating datetime values in PHP and MySQL databases, it is important to use the correct data types and formats to ensure accuracy and consistency. In PHP, you can use the DateTime class to handle datetime values, and in MySQL, you can use the DATETIME data type to store datetime values. When interacting with the database, make sure to properly format datetime values using functions like date() or DateTime::format(). 

// Storing a datetime value in MySQL database
$datetime = new DateTime();
$datetimeString = $datetime->format('Y-m-d H:i:s');
$query = "INSERT INTO table_name (datetime_column) VALUES ('$datetimeString')";
// Execute the query using mysqli or PDO

// Retrieving and manipulating datetime values from MySQL database
$query = "SELECT datetime_column FROM table_name";
// Execute the query using mysqli or PDO
$result = $stmt->fetch();
$datetime = new DateTime($result['datetime_column']);
$datetime->modify('+1 day');
$newDatetimeString = $datetime->format('Y-m-d H:i:s');
