What are common pitfalls when creating tables in PHP?

One common pitfall when creating tables in PHP is not properly escaping user inputs, which can lead to SQL injection attacks. To prevent this, always use prepared statements with parameterized queries when interacting with databases in PHP. 

// Example of creating a table with prepared statements
$stmt = $pdo->prepare("CREATE TABLE IF NOT EXISTS users (
    id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
    username VARCHAR(30) NOT NULL,
    password VARCHAR(255) NOT NULL
)");

$stmt->execute();
