What are some best practices for structuring customer numbers in PHP MySQL databases to avoid potential customer perception issues?

When structuring customer numbers in PHP MySQL databases, it is important to avoid using sensitive information such as social security numbers or phone numbers as customer identifiers to prevent potential privacy concerns. Instead, it is recommended to generate unique customer numbers using a combination of alphanumeric characters or a sequential numeric identifier to maintain anonymity and protect customer data. 

// Generate a unique customer number using a combination of alphanumeric characters
$customerNumber = 'CUST' . uniqid();

// Insert the customer number into the database
$query = "INSERT INTO customers (customer_number, name, email) VALUES ('$customerNumber', 'John Doe', 'johndoe@example.com')";
$result = mysqli_query($connection, $query);

if ($result) {
    echo "Customer added successfully with number: $customerNumber";
} else {
    echo "Error adding customer";
}
