How can PHP beginners effectively troubleshoot issues with form data not being processed correctly?

Issue: PHP beginners can troubleshoot issues with form data not being processed correctly by checking the form method (POST or GET), ensuring the form fields have correct names, and using PHP functions like isset() and $_POST to access form data. 

```php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    if (isset($_POST['submit'])) {
        $name = $_POST['name'];
        $email = $_POST['email'];
        // Process form data here
    }
}
```
In this code snippet, we check if the form was submitted using the POST method and if the submit button was clicked. We then retrieve the form data using $_POST and process it accordingly.
