Are there any specific guidelines or rules to follow when creating interactive elements, such as clickable 10x10-pixel squares with multiple links in PHP?

When creating interactive elements like clickable 10x10-pixel squares with multiple links in PHP, it is important to ensure that each square has a unique identifier and that the links are properly handled when clicked. One way to achieve this is by using HTML image maps to define the clickable areas and their corresponding links. 

<?php
echo '<img src="image.jpg" usemap="#map1">';

echo '<map name="map1">';
echo '<area shape="rect" coords="0,0,10,10" href="link1.php">';
echo '<area shape="rect" coords="10,0,20,10" href="link2.php">';
echo '</map>';
?>
