Hello, i want to split the searchrequest into parts, if there's nothing to find. example: "nelly furtado ft. jimmy jones" -> no results -> try to find with nelly, furtado, jimmy or jones.. i have an api url.. thats the difficult part.. i show you some of the actually snippets:

$query = urlencode (strip_tags ($_GET[search]));

and

 $found = '0';
    if ($source == 'all')
    {
      if (!($res = @get_url ('http://api.example.com/?key=' . $API . '&phrase=' . $query . ' . '&sort=' . $sort)))
      {
        exit ('<error>Cannot get requested information.</error>');
        ;
      }

how can i put a else request in this snippet, like if nothing found take the first word, or the second word, is this possible? or maybe you can tell me were i can read stuff about this function?

thank you!!
