What are the best practices for handling invalid dates like "0000-00-00 00:00:00" in a MySQL table when using PHP to sort and display data?

When handling invalid dates like "0000-00-00 00:00:00" in a MySQL table, it is best to replace them with NULL values to avoid any issues with sorting and displaying data. This can be done using a simple UPDATE query in PHP to set the invalid dates to NULL. 

// Connect to the database
$mysqli = new mysqli("localhost", "username", "password", "database");

// Update invalid dates to NULL
$query = "UPDATE table_name SET date_column = NULL WHERE date_column = '0000-00-00 00:00:00'";
$mysqli->query($query);

// Fetch and display the data
$result = $mysqli->query("SELECT * FROM table_name ORDER BY date_column");
while($row = $result->fetch_assoc()) {
    echo $row['date_column'] . "<br>";
}

// Close the connection
$mysqli->close();
