Are there any best practices for handling form data in PHP arrays?

When handling form data in PHP arrays, it is a best practice to use the $_POST superglobal array to access the form data submitted via POST method. This allows for easy and secure retrieval of form data for processing. Additionally, sanitizing and validating the form data before storing it in PHP arrays can help prevent security vulnerabilities and ensure data integrity. 

// Accessing form data submitted via POST method
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $username = $_POST['username'];
    $email = $_POST['email'];
    
    // Sanitize and validate form data
    $sanitized_username = filter_var($username, FILTER_SANITIZE_STRING);
    $validated_email = filter_var($email, FILTER_VALIDATE_EMAIL);
    
    // Storing form data in PHP arrays
    $formData = [
        'username' => $sanitized_username,
        'email' => $validated_email
    ];
    
    // Process the form data further
    // ...
}
