Are there any potential pitfalls to using multiple submit buttons in a PHP form?

Using multiple submit buttons in a PHP form can lead to ambiguity in determining which button was clicked when the form is submitted. To solve this issue, you can assign a unique name and value to each submit button and then check which button was clicked based on the submitted form data. 

<form method="post" action="process_form.php">
    <!-- Submit button 1 -->
    <button type="submit" name="submit1" value="Submit1">Submit 1</button>
    
    <!-- Submit button 2 -->
    <button type="submit" name="submit2" value="Submit2">Submit 2</button>
</form>
```

In the PHP script (process_form.php), you can check which button was clicked using the following code:

```php
if(isset($_POST['submit1'])) {
    // Code to handle form submission for Submit 1
} elseif(isset($_POST['submit2'])) {
    // Code to handle form submission for Submit 2
} else {
    // Handle other form submissions or no button clicked
}
