What are the best practices for handling form submissions in PHP when using frames?

When handling form submissions in PHP within frames, it is important to target the form submission to the correct frame to ensure the data is processed correctly. This can be achieved by setting the "target" attribute of the form to the name of the frame. Additionally, make sure to include the necessary PHP code to process the form data within the target frame. 

<form action="process_form.php" method="POST" target="frame_name">
  <!-- form fields go here -->
  <input type="submit" value="Submit">
</form>
```

In the process_form.php file within the target frame, you can retrieve the form data using $_POST as usual:

```php
<?php
// process_form.php
if($_SERVER["REQUEST_METHOD"] == "POST") {
  $data = $_POST['data'];
  // process the form data here
}
?>
