Are there best practices for securely transmitting form data in PHP without manually assigning variables for each input field?

When transmitting form data in PHP, it is important to ensure that the data is securely handled to prevent security vulnerabilities such as SQL injection or cross-site scripting attacks. One way to securely transmit form data without manually assigning variables for each input field is to use PHP's `$_POST` superglobal array along with prepared statements for database interactions. This approach helps sanitize the input data and protect against malicious input. 

// Using prepared statements to securely transmit form data in PHP

// Establish a database connection
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

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

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

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

// Bind parameters to the placeholders
$stmt->bind_param("ss", $username, $email);

// Set parameters and execute the statement
$username = $_POST['username'];
$email = $_POST['email'];

$stmt->execute();

// Close the statement and connection
$stmt->close();
$conn->close();
