What are the key components needed to create a PHP form that saves data to a database?

To create a PHP form that saves data to a database, you will need the following key components: 1. HTML form with input fields for user data. 2. PHP script to process form data and save it to the database. 3. Database connection code to establish a connection to the database. Here is a sample PHP code snippet that demonstrates how to create a form that saves data to a database: 

<?php
// Database connection
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Form processing
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $name = $_POST['name'];
    $email = $_POST['email'];

    $sql = "INSERT INTO users (name, email) VALUES ('$name', '$email')";

    if ($conn->query($sql) === TRUE) {
        echo "New record created successfully";
    } else {
        echo "Error: " . $sql . "<br>" . $conn->error;
    }
}

$conn->close();
?>

<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
    Name: <input type="text" name="name"><br>
    Email: <input type="text" name="email"><br>
    <input type="submit" value="Submit">
</form>
