โค้ดการสร้าง tagcloud จาก array ก็ดังรูปเลยครับ
<style type="text/css">
.tag_cloud { padding: 3px; text-decoration: none; }
.tag_cloud:link { color: #81d601; }
.tag_cloud:visited { color: #019c05; }
.tag_cloud:hover { color: #ffffff; background: #69da03; }
.tag_cloud:active { color: #ffffff; background: #ACFC65; }
</style>
<?
function get_tag_data() {
$arr = Array('Actionscript' => 35, 'Adobe' => 22, 'Array' => 44, 'Background' => 43,

$cloud_tags[] = '<a style="font-size: '. floor($size) . 'px'
. '" class="tag_cloud" href="http://www.google.com/search?q=' . $tag
. '" title="' . $tag . '" returned a count of ' . $count . '">'
. htmlspecialchars(stripslashes($tag)) . '</a>';

?>
<h3>Sample Tag Cloud results</h3>
<div id="wrapper" align="center">
<!-- BEGIN Tag Cloud -->
<?php print get_tag_cloud(); ?>
<!-- END Tag Cloud -->
</div>
อันนี้ผมปรับแต่งมาจากเว็บเมืองนอกน่ะครับ
