in chat.php

$data = getCache($room);
while(1){
     if($data == false || empty($data[1]) ) 
 sleep(10);
     else 
        break; }

in sendmemcache.php $value = $_GET['value']; setCache($room,array($username,$value));

However, in infinite loop $data's value never change. I send $value with manuel for sendmemcache.ophp. sendmemcache.php never finish its proces. (Always "Transferring data ....")

How can i resolve this ?
