    hi, great class! In my case I modified showCloud function a bit.

    if(strlen($arrayInfo['url'])){
    $return .= "<a href=\'{$arrayInfo[\'url\']}\' class='word size{$sizeRange}'> &nbsp; {$arrayInfo[\'word\']} &nbsp; </a>";
    }else{
    $return .= "<span class=\'word size{$sizeRange}\'> &nbsp; {$arrayInfo['word']} &nbsp; </span>";
    }

    This way I don't need to get array first and create links myself. This might be useful for other users?

    I think your tutorial should also include the Rewrite Engine rule required to make the domain.dom/tag// link work :)

    I had a problem with this code. I wanted to pass a load of strings into it then have it show the top 10 most popular strings. Perhaps i missed somthing.? isnt this the entire point of a TagCloud?

    There is a bug at the Limit:

    $i = 1;
    foreach ($this->wordsArray as $key => $value) {
    if ($this->limitAmount < $i) {
    $wordsArray[$value['word']] = $value;
    }
    $i++;
    }

    limitAmount $i

    @Gabriel
    When you parse a string into the tag cloud class, it converts the string to tags, you can order and limit the tags using specific methods in the class, these are shown in the tutorial.

    @Arnaud
    Good idea, although this isn't really something i can control as each site system will work differently.

    @Bandorka

    Thanks for the comment, could you please expand on this as it's very difficult for me to replicate the bug you are encountering! Looking at the code, it looks fine to me and i have tested the method and i seem to get the desired results ... ?

    Nice class, great work :)

    Found a bug though, and the fix I believe.

    In the getMax()-method in wordcloud.class.php a "{" and a "}" is missing.

    Before it was this:
    ...
    row 306: if ($c_size > $p_size)
    row 307: $max = $c_size;
    row 308: $p_size = $c_size;

    After my fix:
    ...
    row 306: if ($c_size > $p_size) {
    row 307: max= $c_size;
    row 308: $p_size = $c_size;
    row 309: }

    You can see the bug in action on your demo-page actually. If you view that page and just hits F5 5-10 times you will see how your first Basic Example change appearance (the order), and some times the "weight" of the tags change too. That "randomness" in tag-weight is a bug in my oppinion.

    Indeed it was a minor bug, thank you for mentioning this it is now fixed ;-) and it works a little smoother and consistent when the page is reloaded.

    As each item was looped through only two items were compared in size, now we store the largest item in size and then compare it to each item as it loops through the array.

    Thanks again!

    Hi,

    I was wondering how I would go about using an RSS feed as the data source for your cloud script?

    Any help you could provide would be greatly appreciated.

    All the best.

    Thanks for script. Could you please do some more fixes. For example if you have a small array of tags all of them are getting big size classes. This looks not to good on website.

    Hi, this is what i need, great job, thank you. Before I publish om my site i need some help...i can't make tags w/links working when I use $string for language change dynamically, for example:

    $cloud = new wordCloud();
    $cloud->addWord(array('word' => ''$acc'', 'size' => 1, 'url' => 'http://www.link.com'));
    ...
    where $acc is defined before in several language and change it when language=$language

    how can I define $acc string? with echo don't work ether.
    thank you,
    M.

    Is there anyway to a make it so the tag cloud takes the 10 top used words on the website itself and makes a cloud based on those repetitions? That way each page has a unique page cloud based on the content of the individual pages.

    for a much better speed change all
    return $this->wordsArray;
    to
    return true;

    I've used this code on a couple of websites now, always works perfectly. Thanks :-)

    I added a new utility function:

    /*
    * Sets a limit for the amount of clouds
    * @example setLimitPercent(.50) will show only 50% of the words
    *
    * @param string $limit as a fraction
    *
    * @returns string $this->limitAmount
    */

    function setLimitPercent($limit)
    {
    if (!empty($limit)) {
    $this->limitAmount = round($limit * count($this->wordsArray));
    }
    return $this->limitAmount;
    }

    -------
    It was too much work in my current code base to keep track of unique words and since tagCloud already knew that amount, this function works out really well.
