Added new Algorithm to script, somethings gone wrong?

Hi
On my video site this is the code that merges the results and prepares them for displaying. <?
function getall($searchterms) {

<?
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");
	$wordstmp = fread($fp, filesize($bannedwords));
	fclose($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;	
}

?>

Code (markup):

At the moment this shuffles the results so they are in random order, i want to make them in order of relevance so i found this algorythym

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 have tried just putting this in the place of shuffle and changing the variables, but it doesnt work, how can i make this work? any help is appreciated.

Thanks

 

Please help?
