What is the significance of naming the textarea tag instead of the form tag when using $_POST method in PHP?

When using the $_POST method in PHP, it is important to name the textarea tag (or any other form input) instead of the form tag itself. This is because the form tag does not carry any data when submitted, only the form inputs do. Therefore, if you want to retrieve the data from a textarea input using $_POST, you must name the textarea itself. 

```php
<form method="post" action="process_form.php">
    <textarea name="message"></textarea>
    <input type="submit" value="Submit">
</form>
```

In the above code snippet, the textarea input is named "message", so when the form is submitted, the data entered into the textarea can be accessed using $_POST['message'].
