php Flash标签云(flash tagcloud)的实现代码

<?php
require("config.php");
require_once 'Tags.php';   
$sql = "SELECT tags FROM demo";  //在这里你可以随机或者限制一下取出的个数. 
$rs = $db->query($sql);
while ($tags = $db->fetch_array($rs)) {
     $arr[] = split("\|",iconv("gb2312","utf-8",$tags['tags']));
}
$tags = new Tags($arr);
$tagsArr = $tags->getTags();
$tagsStr = '<tags>'; 
foreach ($tagsArr as $value){
     $tagsStr .= urlencode('<a href="testtags.php?action='.urlencode($value).'" style="font-size:'.rand(8,24).'pt;">'.$value.'</a>');
}
$tagsStr .= '</tags>';
?>

<script type="text/javascript">
    var rnumber = Math.floor(Math.random()*9999999); 
    var cloud = new SWFObject("Tags/tagcloud.swf?r="+rnumber, "tagcloudflash", "250", "250", "9", "#ffffff");
