Hi
This is a script which combines many different video feeds together, at the moment you can see that it
PHP Code:
shuffle($all); 
instead of an algorithm to sort the records, i would like to change it so that it is sorted by relevancy to a string which i could specify. Here is the whole code for the page, and bellow that is an algoryhtym which i tried to implement into the code but would not work. Can anyone either help me implement this algorithm or write one that will work with this code?
PHP Code:
<?
function getall($searchterms) {
    require(
"yt.php");
    require(
"gv.php");
    require(
"dm.php");
    require(
"mc.php");
    
    
$yt yt($searchterms);
    
$gv gv($searchterms);
    
$dm dm($searchterms);
    
$mc mc($searchterms);
    
    
$all array_merge($yt,$gv,$dm,$mc);
    if(
count($all)) {
        include_once 
"latest.php";
        
updatelatest(str_replace("+","-",$searchterms));    
    }
    
$bannedwords "bannedwords.txt";
    
$fp fopen($bannedwords"r");
    
$wordstmp fread($fpfilesize($bannedwords));
    
fclose($fp);
    
$words explode("\n",$wordstmp);
    
$words array_map("strtolower",$words);
    
    foreach(
$all as $index=>$arr) {
        
$arrtitle $arr['title'];
        foreach(
$words as $index2=>$word) {
            if(
strstr(strtolower($arrtitle),strtolower(str_replace("\n","",str_replace("\r","",$word))))) {
                unset(
$all[$index]);
                break;    
            }
        }
    }
    
    
srand((float)microtime() * 1000000);
    
shuffle($all);
    foreach(
$all as $j=>$k) {
        if(!
trim($k['title'])||!trim($k['link']))
            unset(
$all[$j]);    
    }

    return 
$all;    
}

?>
This is the sort of algorythym

PHP Code:
usort($multifeed,'funnySort');

function 
funnySort($a,$b)
{
    
// assign numerical value so we can sort on 
        // whether "term" is in title or content or neither

    
$term 'funny';

    
$x 0;    
    if (
stripos($a->get_title(),$term))
        
$x 2;
    elseif (
stripos($a->get_content(),$term))
        
$x 1;

    
$y 0;    
    if (
stripos($b->get_title(),$term))
        
$y 2;
    elseif (
stripos($b->get_content(),$term))
        
$y 1;

    return 
$x <= $y


i also tried to use this code on this site http://www.webmastersherpa.com/tools/search.txt


Please can someone either help me adapt either of these algorithms or help me write one that will work with my code.
