How can HTML select or checkbox elements be used to handle multiple form actions in PHP?

When using HTML select or checkbox elements in a form, we can handle multiple form actions in PHP by checking the submitted values of these elements and executing different actions based on those values. We can use conditional statements in PHP to determine which action to take based on the selected options in the form. 

```php
<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    if (isset($_POST['action'])) {
        $action = $_POST['action'];
        
        switch ($action) {
            case 'option1':
                // Handle action for option 1
                break;
            case 'option2':
                // Handle action for option 2
                break;
            // Add more cases for additional options if needed
        }
    }
}
?>
```
In this code snippet, we are checking if a form has been submitted using the POST method. We then check the value of the 'action' parameter in the form data to determine which action to take based on the selected option. This allows us to handle multiple form actions in PHP based on the selected values of the HTML select or checkbox elements.
