What are the advantages and disadvantages of using DATETIME vs. TIMESTAMP data types for date and time values in MySQL when importing CSV data with PHP?

When importing CSV data with PHP into MySQL, it's important to consider whether to use DATETIME or TIMESTAMP data types for date and time values. Advantages of using DATETIME: - DATETIME allows for a wider range of dates (from '1000-01-01 00:00:00' to '9999-12-31 23:59:59'). - DATETIME is not affected by the time zone settings of the server. Disadvantages of using DATETIME: - DATETIME requires more storage space compared to TIMESTAMP. - DATETIME does not automatically update when the row is modified. Advantages of using TIMESTAMP: - TIMESTAMP requires less storage space compared to DATETIME. - TIMESTAMP automatically updates when the row is modified. Disadvantages of using TIMESTAMP: - TIMESTAMP has a more limited range of dates (from '1970-01-01 00:00:01' UTC to '2038-01-19 03:14:07' UTC). - TIMESTAMP is affected by the time zone settings of the server. To import CSV data with PHP into MySQL and choose between DATETIME and TIMESTAMP data types for date and time values, you can use the following code snippet:

// Assuming $csvData is an array containing the CSV data to be imported

// Connect to MySQL database
$mysqli = new mysqli('localhost', 'username', 'password', 'database');

// Loop through the CSV data and insert into MySQL table
foreach($csvData as $row) {
    $date = date('Y-m-d H:i:s', strtotime($row['date_time']));

    // Using DATETIME data type
    $query = "INSERT INTO table_name (date_time_column) VALUES ('$date')";
    $mysqli->query($query);

    // Using TIMESTAMP data type
    $query = "INSERT INTO table_name (date_time_column) VALUES (TIMESTAMP('$date'))";
    $mysqli->query($query);
}

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