What are the key considerations for handling form data submission and processing in PHP to ensure successful database insertion?

When handling form data submission in PHP to ensure successful database insertion, it is important to properly sanitize and validate the input data to prevent SQL injection and other security vulnerabilities. Additionally, make sure to establish a database connection, prepare the SQL statement with placeholders for the user input, bind the parameters, and execute the query to insert the data into the database. 

// Assuming you have already established a database connection

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

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

// Bind the parameters
$stmt->bindParam(':name', $name);
$stmt->bindParam(':email', $email);

// Execute the query to insert the data into the database
$stmt->execute();
