How do you handle errors in a multi-table database system in PHP to prevent cascading failures?

In a multi-table database system in PHP, errors can lead to cascading failures if not handled properly. To prevent this, you should use try-catch blocks to catch and handle exceptions that may occur during database operations. By handling errors gracefully, you can prevent them from propagating through the system and causing further issues. 

try {
    // Perform database operations here
} catch (PDOException $e) {
    // Handle the exception, log the error, and prevent cascading failures
    echo "An error occurred: " . $e->getMessage();
}
