What are the best practices for formatting and storing dates in a MySQL database using PHP?

When storing dates in a MySQL database using PHP, it is best practice to use the `DATETIME` data type in MySQL for storing date and time values. This data type provides a standard format for date and time values and allows for easy manipulation and comparison of dates in queries. When inserting dates into the database, it is recommended to use the `date()` function in PHP to format the date in the desired format before inserting it into the database.

// Assuming $date is the date value to be inserted into the database
$formatted_date = date('Y-m-d H:i:s', strtotime($date));
$query = "INSERT INTO table_name (date_column) VALUES ('$formatted_date')";
// Execute the query to insert the formatted date into the database
