How can you differentiate between multiple forms on a webpage in PHP?

When dealing with multiple forms on a webpage in PHP, you can differentiate between them by giving each form a unique name or ID attribute. This way, when the form is submitted, you can check which form was submitted by checking the name or ID in the $_POST or $_GET superglobal arrays. This allows you to handle each form submission separately based on the form identifier. 

<form name="form1" method="post" action="process_form.php">
    <!-- Form 1 fields here -->
    <input type="submit" name="submit_form1" value="Submit Form 1">
</form>

<form name="form2" method="post" action="process_form.php">
    <!-- Form 2 fields here -->
    <input type="submit" name="submit_form2" value="Submit Form 2">
</form>
```

In the `process_form.php` file, you can differentiate between the forms by checking the submitted form data:

```php
if(isset($_POST['submit_form1'])) {
    // Process Form 1 data
} elseif(isset($_POST['submit_form2'])) {
    // Process Form 2 data
}
