What are some common pitfalls when using PHP to fill a table with data from a form?

One common pitfall when using PHP to fill a table with data from a form is not properly sanitizing user input, which can lead to SQL injection attacks. To solve this issue, always use prepared statements or parameterized queries to safely insert data into the database. 

// Example of using prepared statements to insert form data into a table
$stmt = $pdo->prepare("INSERT INTO table_name (column1, column2) VALUES (:value1, :value2)");
$stmt->bindParam(':value1', $value1);
$stmt->bindParam(':value2', $value2);

// Assuming $value1 and $value2 are retrieved from the form
$value1 = $_POST['value1'];
$value2 = $_POST['value2'];

$stmt->execute();
