What best practices should be followed when creating a form in PHP to insert data into a database?

When creating a form in PHP to insert data into a database, it is important to follow best practices to ensure data integrity and security. Some key practices include validating user input to prevent SQL injection attacks, sanitizing input to prevent cross-site scripting attacks, and using prepared statements to securely interact with the database. 

<?php
// Validate and sanitize user input
$name = filter_var($_POST['name'], FILTER_SANITIZE_STRING);
$email = filter_var($_POST['email'], FILTER_SANITIZE_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();

// Redirect the user after successful insertion
header('Location: success.php');
exit();
?>
