how to use the cloud_tag class (see post below for class source):
// create some fake input
$tags = array();
$tempTag[tag_name] = \'ajax\';
$tempTag[tag_count] = 3;
$tags[] = $tempTag;
$tempTag[tag_name] = \'mysql\';
$tempTag[tag_count] = 3;
$tags[] = $tempTag;
$tempTag[tag_name] = \'linux\';
$tempTag[tag_count] = 1;
$tags[] = $tempTag;
$tempTag[tag_name] = \'php\';
$tempTag[tag_count] = 6;
$tags[] = $tempTag;
// instantiate a cloud
$cloud = new cloud_tag();
// the class already has defaults, but let\'s override them for fun
$cloud->set_label(\'cloud\'); // css classes will be cloud1, cloud2, etc.
$cloud->set_tagsizes(7); // 7 font sizes will be used
$newtags = $cloud->make_cloud($tags); // make a tag cloud
