Exlude key words?

    In a code like this:

    <?php
    $pid = "111111"; // put your CJ pid here
    $keyword = "Steel chain"; // put your keyword here
    $display = "15"; // how many items to display
    include "blahblah.php";
    ?>

    Now I am including key words. Is it possible to exclude words in any way?

    Green rep to good answers :)

    Thanks.

    No one is going to be able to answer your question with the info you're providing.

    Post the code that uses the keywords...

    Ok, here it is, do you need the lastrss.php to?

    <?php
    if ($display==''){$display=3;}
    if ($pid==''){$pid='00000';}
    $keyword = str_replace(' ', '+', $keyword);
    $url = 'rss.api.ebay.com/ws/rssapi?FeedName=SearchResults&siteId=0&language=en-US&output=RSS20&sacqy=&catref=C5&sacur=0&from=R6&saobfmts=exsif&dfsp=1&sacqyop=ge&saslc=0&floc=1&sabfmts=0&saprclo=&saprchi=&saaff=afcj&ftrv=1&ftrt=1&fcl=3&frpp=50&afcj='.$pid.'&nojspr=yZQy&satitle='.$keyword.'&afmp=&sacat=-1&saslop=1&fss=0';
    $rsscount = null;
    include_once './lastRSS.php';
    $rss = new lastRSS;
    $rss->cache_dir = './cache';
    $rss->cache_time = 3600; // one hour
    if ($rs = $rss->get($url)) {
    foreach ($rs['items'] as $item) {
    $rsscount++;
    if (($rsscount < ($display+1))) {
    $ebay = '<a href="'.$item[link].'"><b>'.$item[title].'</b></a>'.$item[description].'<hr size="1" noshade="noshade" />';
    $ebay = str_replace('<a', '<a rel="nofollow"', $ebay);
    echo $ebay;
    }}}
    ?>



    Ok, here ist the lastrss.php:
