PHP Script Mod to not allow banned words search

I have a video script to pull youtube videos.

The script is very basic and allows any word search's.

I want to include a bannedword part to stop
any searches for the obvious unwanted words
that are on some youtube videos.

Presumably a $bannedwords array in the main
config file.

Can anyone help with whats needed to the script.

$keyword is the subject of the search,
ie $keyword = golf

Heres the part of the script that needs modding.

<?
function YT_ListByTag($keyword, $page=1) {
global $config;

$keyword = urlencode($keyword);

$start_index = ($page - 1) * $config['list_per_page'] + 1;

$req = "http://gdata.youtube.com/feeds/videos?vq={$keyword}".
"&start-index={$start_index}".
"&max-results={$config['list_per_page']}".
"&orderby=updated";

if($config['xml_cache_enable']) {
$data[1] = YT_GetXMLRespCache($req);
}
else {
$data[1] = REST_Request($req);
}

$data[0] = Xml2Array($data[1]);

return $data;
}

Any help welcome.

Thanks


Terry

Thanks Stoli

Your code worked great.

function YT_ListByTag($keyword, $page=1) {
global $config;

$bannedwords = array("banned", "words", "here");

if (in_array($keyword, $bannedwords)) {
    // keyword is banned
    return;
}

$keyword = urlencode($keyword);

$start_index = ($page - 1) * $config['list_per_page'] + 1;

$req = "http://gdata.youtube.com/feeds/videos?vq={$keyword}".
"&start-index={$start_index}".
"&max-results={$config['list_per_page']}".
"&orderby=updated";

if($config['xml_cache_enable']) {
$data[1] = YT_GetXMLRespCache($req);
}
else {
$data[1] = REST_Request($req);
}

$data[0] = Xml2Array($data[1]);

return $data;
}
