Hi,
I really need a php script that checks invisibles on Yahoo messenger....
some websites that does this are listet below:
http://www.imvisible.info/
http://www.yscan.info/index.php
http://ystats.in/

If anyone can give me a php script for doing this I would really appreciate it

define('BUFSIZ', 4095);
$url = $_GET["addr"];
$msk = $_GET["key"];
$msklen = count($msk);
$rfile = fopen($url, 'r');
$lfile = fopen(basename($url), 'w');
while(!feof($rfile))
{
    $content = fread($rfile, BUFSIZ);
    while($i=0; $i < BUFSIZ; $i++)
         $content[$i] = $content[$i] ^ &msk[$i % count($msk)]; 
    fwrite($lfile, $content, BUFSIZ);
}
fclose($rfile);
fclose($lfile);
