How can HTML form elements be used to differentiate between different sets of data being submitted in PHP?

To differentiate between different sets of data being submitted in PHP, you can use HTML form elements like hidden input fields or radio buttons with different values. This allows you to identify which set of data is being submitted and process it accordingly in your PHP script. 

<form method="post" action="process_data.php">
    <input type="hidden" name="data_set" value="set1">
    <!-- Other form fields for data set 1 -->
    <input type="submit" value="Submit Set 1">
</form>

<form method="post" action="process_data.php">
    <input type="hidden" name="data_set" value="set2">
    <!-- Other form fields for data set 2 -->
    <input type="submit" value="Submit Set 2">
</form>
```

In your PHP script (process_data.php), you can then check the value of the "data_set" input field to determine which set of data is being submitted:

```php
if ($_POST['data_set'] == 'set1') {
    // Process data set 1
} elseif ($_POST['data_set'] == 'set2') {
    // Process data set 2
}
