What are common pitfalls when using PHP for creating tables and how can they be avoided?

Common pitfalls when using PHP for creating tables include not sanitizing user input, not properly handling errors, and not using prepared statements for executing SQL queries. To avoid these pitfalls, always sanitize user input to prevent SQL injection attacks, handle errors gracefully by checking for errors after executing queries, and use prepared statements to securely execute SQL queries. 

// Example of creating a table in PHP with error handling and prepared statements

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

// Create table query
$query = "CREATE TABLE IF NOT EXISTS users (
            id INT(11) AUTO_INCREMENT PRIMARY KEY,
            username VARCHAR(50) NOT NULL,
            email VARCHAR(50) NOT NULL
          )";

// Execute query with error handling
if($pdo->exec($query) === false){
    die("Error creating table: " . print_r($pdo->errorInfo(), true));
}

// Close connection
$pdo = null;
