What are the potential consequences of using different versions of MySQL in the test and production environments in PHP development?

Using different versions of MySQL in test and production environments can lead to compatibility issues, resulting in unexpected behavior or errors in your PHP application. To avoid this, it is recommended to ensure that the MySQL versions are the same in both environments. This can be achieved by setting up a consistent development workflow and using tools like Docker to create identical environments for testing and production. 

// Sample PHP code to check MySQL version before connecting

$mysql_version = mysqli_get_server_info($connection);

if ($mysql_version != '5.7.32') {
    die("MySQL version mismatch. Please ensure the same version is used in both test and production environments.");
}

// Proceed with connecting to MySQL and running queries
