How can differences between two texts be highlighted using PHP?

To highlight the differences between two texts using PHP, you can utilize the `Diff` class from the `Text_Diff` package. This class can be used to compare two texts and generate a visual diff output that highlights the added, removed, and changed parts between them. 

require_once 'Text/Diff.php';

$text1 = "Lorem ipsum dolor sit amet, consectetur adipiscing elit.";
$text2 = "Lorem ipsum dolor sit amet, adipiscing elit.";

$diff = new Text_Diff('auto', array(explode(' ', $text1), explode(' ', $text2)));
$renderer = new Text_Diff_Renderer_inline();

echo $renderer->render($diff);
