Are there any specific considerations when using multiple forms in PHP, as seen in the function.php code snippet?

When using multiple forms in PHP, it is important to ensure that each form has a unique identifier to distinguish them when processing the submitted data. One way to achieve this is by adding a hidden input field with a unique value for each form. This hidden input field can be used to identify which form was submitted and take appropriate actions based on that. 

<form action="process_form.php" method="post">
    <input type="hidden" name="form_id" value="form1">
    <!-- Other form fields -->
    <button type="submit">Submit Form 1</button>
</form>

<form action="process_form.php" method="post">
    <input type="hidden" name="form_id" value="form2">
    <!-- Other form fields -->
    <button type="submit">Submit Form 2</button>
</form>
```

In the `process_form.php` file, you can then check the value of the `form_id` field to determine which form was submitted and process the data accordingly.

```php
<?php
if(isset($_POST['form_id'])) {
    $form_id = $_POST['form_id'];

    if($form_id == 'form1') {
        // Process data for Form 1
    } elseif($form_id == 'form2') {
        // Process data for Form 2
    }
}
?>
