What common pitfalls should be avoided when dynamically creating database tables in PHP?

One common pitfall to avoid when dynamically creating database tables in PHP is not properly sanitizing user input, which can lead to SQL injection attacks. To prevent this, always use prepared statements with parameterized queries to securely insert user input into SQL statements. 

// Example code snippet using prepared statements to dynamically create a database table

// Assume $tableName and $columnName are user inputs
$tableName = $_POST['tableName'];
$columnName = $_POST['columnName'];

// Connect to the database
$pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");

// Prepare the SQL statement with placeholders
$stmt = $pdo->prepare("CREATE TABLE $tableName ($columnName VARCHAR(255))");

// Execute the prepared statement
$stmt->execute();
