What common mistakes are made when creating tables in PHP?

One common mistake when creating tables in PHP is not properly sanitizing user input, which can lead to SQL injection attacks. To solve this issue, always use prepared statements with parameterized queries to prevent SQL injection vulnerabilities. 

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