What are the limitations of using PHP to create image maps with dynamic links?

When using PHP to create image maps with dynamic links, one limitation is that the image map coordinates need to be hardcoded in the HTML code, making it difficult to dynamically change the links based on user input or database values. To solve this issue, you can use PHP to generate the entire image map HTML code dynamically, including the coordinates and links. 

<?php
// Array containing image map coordinates and corresponding links
$imageMap = [
    ['x1', 'y1', 'x2', 'y2', 'link1'],
    ['x3', 'y3', 'x4', 'y4', 'link2'],
    // Add more coordinates and links as needed
];

// Generate the image map HTML code dynamically
echo '<map name="dynamicMap">';
foreach ($imageMap as $coords) {
    echo '<area shape="rect" coords="' . implode(',', $coords) . '" href="' . $coords[4] . '">';
}
echo '</map>';

// Output the image map with an image
echo '<img src="image.jpg" usemap="#dynamicMap">';
?>
