What are the advantages of using DATETIME data type in MySQL for timestamp calculations over PHP functions?

When dealing with timestamp calculations in MySQL, using the DATETIME data type is advantageous over PHP functions because MySQL has built-in functions for date and time calculations, which can simplify and optimize your queries. This can improve performance and reduce the amount of code needed in your PHP scripts. Additionally, storing timestamps as DATETIME in MySQL allows for easier sorting, filtering, and comparison operations directly in the database. 

// Example of using DATETIME data type in MySQL for timestamp calculations
// Assuming we have a table named 'events' with a column 'event_date' of type DATETIME

// Get the current date and time in PHP
$currentDateTime = date('Y-m-d H:i:s');

// Insert a new event with the current date and time
$query = "INSERT INTO events (event_date) VALUES ('$currentDateTime')";
// Execute the query using your MySQL connection

// Retrieve events that occurred after a specific date
$startDate = '2022-01-01';
$query = "SELECT * FROM events WHERE event_date > '$startDate'";
// Execute the query using your MySQL connection
