How can PHP developers ensure data integrity and security when automating form data processing for database insertion?

To ensure data integrity and security when automating form data processing for database insertion, PHP developers can use prepared statements with parameterized queries to prevent SQL injection attacks. Additionally, input validation should be performed to sanitize and validate user input before inserting it into the database. 

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

// Prepare a SQL statement with placeholders for parameters
$stmt = $pdo->prepare("INSERT INTO users (username, email) VALUES (:username, :email)");

// Bind the parameters with user input
$stmt->bindParam(':username', $_POST['username']);
$stmt->bindParam(':email', $_POST['email']);

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