How can PHP variables be accessed dynamically when values are passed from a form?

When values are passed from a form, PHP variables can be accessed dynamically using the $_POST or $_GET superglobals. These superglobals allow us to retrieve form data based on the input field names. By accessing form data dynamically, we can process and manipulate the values submitted by the user easily. 

// Example code to access form data dynamically
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $username = $_POST['username'];
    $password = $_POST['password'];
    
    // Process the form data as needed
    echo "Username: " . $username . "<br>";
    echo "Password: " . $password;
}
