How can PHP developers ensure their scripts remain functional even with changes in the design of a webpage?

PHP developers can ensure their scripts remain functional despite changes in webpage design by using CSS classes or IDs to target specific elements for manipulation rather than relying on specific HTML structure. This way, even if the layout of the webpage changes, the PHP script will still be able to interact with the intended elements. 

<?php
// Example of using CSS classes to target elements
echo '<div class="content">Hello, world!</div>';

// PHP script targeting elements with class 'content'
$elements = $dom->getElementsByClassName('content');
foreach ($elements as $element) {
    echo $element->textContent;
}
?>
