What are some best practices for structuring PHP code, especially when dealing with form processing and object-oriented programming?

When dealing with form processing in PHP, it is important to separate your logic into different files or classes to maintain a clean and organized codebase. One common approach is to create a separate file for handling form submissions, where validation and processing logic is contained. Additionally, using object-oriented programming principles can help streamline your code and make it more maintainable. 

// form_processing.php

class FormProcessor {
    public function processForm($formData) {
        // Validation logic here
        // Processing logic here
    }
}

// index.php

if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $formProcessor = new FormProcessor();
    $formProcessor->processForm($_POST);
}
