How can a link be created to display the complete text from a database using PHP?

To display the complete text from a database using PHP, you can create a link that redirects to a separate page where the full text is displayed. This can be achieved by passing an identifier (such as an ID) through the URL to retrieve the relevant data from the database.

```php
// Assuming $row is the database row containing the text and an ID field

echo "<a href='full_text.php?id=" . $row['id'] . "'>Read More</a>";
```

In the `full_text.php` file, you can retrieve the ID from the URL and fetch the complete text from the database based on that ID to display it on the page.
