How do you handle form data submission and processing in Zend Framework?

Answer: In Zend Framework, form data submission and processing is typically handled by following these steps:

1. Create a Form Class: Define a form by extending `ZendFormForm` and add elements and validation rules.

2. Controller Action: In your controller, create an action method to handle the form. Instantiate the form and check if it is submitted using the `isPost()` method.

3. Bind Data: If the form is submitted, use `setData($this->getRequest()->getPost())` to bind the submitted data to the form.

4. Validation: Call `isValid()` to validate the form data. If valid, process the data (e.g., save to the database).

5. Error Handling: If not valid, retrieve error messages and repopulate the form for user correction.

6. Rendering the Form: Render the form in the view, typically using a view script.

This approach enables structured and efficient handling of form submissions.
