How can PHP developers ensure compatibility of date values between PHP and MySQL databases?

To ensure compatibility of date values between PHP and MySQL databases, PHP developers should use the same date format for both systems. This can be achieved by using the 'Y-m-d H:i:s' format for dates, as it is compatible with MySQL's DATETIME data type. Additionally, developers should set the timezone for both PHP and MySQL to ensure consistency in date and time calculations. 

// Set the timezone for PHP
date_default_timezone_set('UTC');

// Set the timezone for MySQL
$mysqli = new mysqli('localhost', 'username', 'password', 'database');
$mysqli->query("SET time_zone = '+00:00'");
