What potential pitfalls should beginners be aware of when importing data into a database with PHP?

Beginners should be aware of potential pitfalls such as SQL injection attacks when importing data into a database with PHP. To prevent this, it is important to use prepared statements or parameterized queries to sanitize user input before inserting it into the database. 

// Using prepared statements to prevent SQL injection
$stmt = $pdo->prepare("INSERT INTO table_name (column1, column2) VALUES (:value1, :value2)");
$stmt->bindParam(':value1', $value1);
$stmt->bindParam(':value2', $value2);
$stmt->execute();
