When expanding the functionality to store additional information about teams, such as the date since they have been trained, the database design will impact the scalability and maintainability of the PHP application. It is important to ensure that the database schema is well-structured to efficiently store and retrieve this new information. This includes creating appropriate tables, relationships, and indexes to support the new data requirements. 

// Example of adding a new column for training date in the teams table
$sql = "ALTER TABLE teams ADD training_date DATE";
if ($conn->query($sql) === TRUE) {
    echo "Training date column added successfully";
} else {
    echo "Error adding training date column: " . $conn->error;
}
