How can PHP developers effectively manage and generate unique identifiers, such as invoice numbers, in a database system?

Managing and generating unique identifiers, such as invoice numbers, in a database system can be achieved by using auto-increment primary keys in database tables or by generating unique identifiers programmatically in PHP before inserting records into the database. 

// Generate a unique invoice number
$invoiceNumber = uniqid('INV-');

// Insert data into the database table with the generated invoice number
$query = "INSERT INTO invoices (invoice_number, amount, customer_id) 
          VALUES ('$invoiceNumber', '$amount', '$customer_id')";
$result = mysqli_query($connection, $query);

if ($result) {
    echo "Invoice created successfully with number: $invoiceNumber";
} else {
    echo "Error creating invoice";
}
