What are the implications of assigning the same ID to multiple elements in PHP-generated HTML?

Assigning the same ID to multiple elements in PHP-generated HTML can lead to conflicts and unexpected behavior when trying to target those elements using JavaScript or CSS. To solve this issue, ensure that each element has a unique ID by appending a unique identifier, such as a counter or a random string, to the ID when generating the HTML. 

<?php
// Example code to assign unique IDs to elements in PHP-generated HTML
$elements = ['element1', 'element2', 'element3'];

foreach ($elements as $key => $element) {
    $unique_id = $element . '_' . $key; // Append a unique identifier
    echo "<div id='$unique_id'>Element $key</div>";
}
?>
