Php: Symlink Script

[nsane]

i wrote most of it but i found the delete file & symlink parts in a tutorial i read a while back (been tinkering with it for a while )

any ways, everything works except it wont delete the files

<?php

$refs = "ref.txt";
$getref = getenv(HTTP_REFERER);
$start = "TRUE";
$addref = 0;
$fp = fopen($refs,"r");
while (!feof($fp)){$line = fgets($fp, 4096); $line=trim($line);
if ($line != ""){$addref++;}
if ($line==$getref){$start = "FALSE";}}
fclose($fp);
if ($start == "TRUE"){$fp = fopen($refs,"a");fwrite($fp, "\n");fwrite($fp, $getref);fclose($fp);$addref++;}

if(
$HTTP_REFERER=="http://www.geocities.com/kazaalite243/download_kazaa_lite_here.html" ||

){header("Location: /index.htm");}else{

    if(isset($_REQUEST["file"])){
    $name=basename($_REQUEST["file"]);
    $file="/home/site/public_html/nsane/dl/".$name;
    if($name==""){header("Location: /index.htm");}

        if(file_exists($file)&&is_file($file)){
        umask("0000");
        $newdir=md5(crypt("random"));
        $size=filesize($file);
        if(ereg(".rar",$name)){$type="application/x-rar-compressed";}
        elseif(ereg(".zip",$name)){$type="application/x-zip-compressed";}
        elseif(ereg(".exe",$name)){$type="application/x-msdownload";}
        else{$type="application/octet-stream";}
        mkdir("/home/site/public_html/nsane/sym/$newdir/");
        symlink("/home/site/public_html/nsane/dl/$name","/home/site/public_html/nsane/sym/$newdir/$name");
        header("Location: /sym/$newdir/$name");

           $root="/home/site/public_html/nsane/sym/";
           if($handle=opendir($root)){
           while(false !== ($dir = readdir($handle))){
           if ($dir != "." && $dir != ".." && $dir != ".htaccess" && $dir !== "index.php"){
           $made=filectime("$root/$dir");
           $now=time();
           $diff=($now-$made)/60;
           if ($diff > 30){
           system("rm -r $root/$dir");}}}
           closedir($handle);exit();}

        }else{header("Location: /index.htm");}

    }else{header("Location: /index.htm");}

}

nevermind, just relized the delete folder part was meant to be used as a different file. which you run to delete folders older than 30 minutes old

works perfect now, tho
