What best practices should be followed when naming and structuring database columns to avoid errors in PHP scripts?

When naming and structuring database columns in PHP scripts, it is essential to follow best practices to avoid errors. One common practice is to use descriptive and consistent column names that reflect the data they store. Additionally, it is recommended to avoid using reserved words, special characters, or spaces in column names to prevent conflicts and syntax errors in SQL queries. Lastly, maintaining a standardized naming convention, such as using camelCase or underscores, can improve code readability and organization. 

// Example of creating a table with properly named columns in PHP
$sql = "CREATE TABLE users (
    user_id INT(11) AUTO_INCREMENT PRIMARY KEY,
    username VARCHAR(50) NOT NULL,
    email VARCHAR(100) NOT NULL,
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
)";
mysqli_query($conn, $sql);
