What resources or tutorials would you recommend for beginners looking to improve their understanding of PHP timestamp manipulation in database operations?

When working with database operations in PHP, it is essential to understand how to manipulate timestamps effectively. One common task is converting timestamps between PHP and database formats, such as from Unix timestamp to MySQL datetime format. To improve your understanding of PHP timestamp manipulation in database operations, I recommend checking out the official PHP documentation on date and time functions, as well as online tutorials and forums for practical examples and best practices.

// Convert Unix timestamp to MySQL datetime format
$unixTimestamp = time(); // Current Unix timestamp
$mysqlDatetime = date('Y-m-d H:i:s', $unixTimestamp); // Convert Unix timestamp to MySQL datetime format

echo $mysqlDatetime; // Output: Current datetime in MySQL format
