What are the drawbacks of using numbered fields in a database table design for PHP applications?

Using numbered fields in a database table design for PHP applications can make the code harder to maintain and understand. It can also lead to issues when adding or removing fields from the table. To solve this, it's better to use descriptive field names that clearly indicate the data they hold. 

// Example of using descriptive field names in a database table design
$sql = "CREATE TABLE users (
    id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
    username VARCHAR(30) NOT NULL,
    email VARCHAR(50) NOT NULL,
    password VARCHAR(255) NOT NULL
)";
