What are the potential issues with using duplicate IDs in HTML elements and how can they be avoided in PHP applications?

Using duplicate IDs in HTML elements can cause issues with JavaScript functionality and CSS styling, as IDs should be unique within a document. To avoid this problem in PHP applications, you can dynamically generate unique IDs using a counter variable or a random string generator. 

<?php
// Generate a unique ID using a counter variable
$counter = 1;
$id = "element_" . $counter;
$counter++;

// Use the generated ID in your HTML element
echo "<div id='$id'>Unique element</div>";
?>
