How can object-oriented programming principles be applied to improve the handling of form data in PHP, as demonstrated in the forum thread?

Issue: The handling of form data in PHP can become messy and hard to maintain as the codebase grows. By applying object-oriented programming principles such as encapsulation, inheritance, and polymorphism, we can create classes to represent form fields, validate input, and process data more efficiently. 

class FormField {
    private $name;
    private $value;

    public function __construct($name, $value) {
        $this->name = $name;
        $this->value = $value;
    }

    public function getName() {
        return $this->name;
    }

    public function getValue() {
        return $this->value;
    }

    public function validate() {
        // Add validation logic here
    }

    public function process() {
        // Add processing logic here
    }
}

// Usage example
$nameField = new FormField('name', $_POST['name']);
$nameField->validate();
$nameField->process();
