What best practices should be followed when validating form data before inserting it into a database using PHP?

When validating form data before inserting it into a database using PHP, it is important to sanitize and validate the input to prevent SQL injection attacks and ensure data integrity. This can be done by using PHP filters and prepared statements to sanitize and validate user input before inserting it into the database. 

// Example of validating form data before inserting into a database using PHP

// Sanitize and validate form data
$name = filter_var($_POST['name'], FILTER_SANITIZE_STRING);
$email = filter_var($_POST['email'], FILTER_VALIDATE_EMAIL);

// Create a prepared statement to insert data into the database
$stmt = $pdo->prepare("INSERT INTO users (name, email) VALUES (:name, :email)");
$stmt->bindParam(':name', $name);
$stmt->bindParam(':email', $email);

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