How can PHP timestamps be converted to MySQL timestamps for database storage?

PHP timestamps can be converted to MySQL timestamps for database storage by using the `date()` function in PHP to format the timestamp in a way that MySQL can understand. The format commonly used for MySQL timestamps is "Y-m-d H:i:s". By converting the PHP timestamp to this format, it can be easily stored in a MySQL database.

$phpTimestamp = time(); // Get current PHP timestamp
$mysqlTimestamp = date('Y-m-d H:i:s', $phpTimestamp); // Convert PHP timestamp to MySQL timestamp format

// Now $mysqlTimestamp can be stored in a MySQL database
