What best practices should be followed when dealing with arrays and form data in PHP for database storage?

When dealing with arrays and form data in PHP for database storage, it's important to properly sanitize and validate the input to prevent SQL injection attacks and ensure data integrity. Using prepared statements with parameterized queries is a best practice to securely insert array data into a database. 

// Assuming $formData is an array containing form data
$stmt = $pdo->prepare("INSERT INTO table_name (column1, column2) VALUES (:value1, :value2)");

foreach ($formData as $data) {
    $stmt->bindParam(':value1', $data['value1']);
    $stmt->bindParam(':value2', $data['value2']);
    $stmt->execute();
}
