he request and redis lpop(queue,timeout) to wait for the token, and send data out, something like this:
<?php
    require __DIR__.'/predis-1.0/autoload.php';
    header("Content-Type: text/event-stream");
    header("Cache-Control: no-cache");
    header("Connection: keep-alive");

    $lastId = isset($_SERVER["HTTP_LAST_EVENT_ID"]) ? 
              $_SERVER["HTTP_LAST_EVENT_ID"] : null;
    if (isset($lastId) && !empty($lastId) && is_numeric($lastId)) {
        $lastId = intval($lastId);
        $lastId++;
    }

    $index = isset($_GET['index']) ? $_GET['index'] : null;

    echo "retry: 2000\n";

    $client = new Predis\Client();
    while (true) {
        $data = $client->blpop('queue',5);
        if ($data) {
            error_log("$index : " . strlen($data));
            sendMessage($lastId, $data);
            $lastId++;
        }
    }

    function sendMessage($id, $data) {
        echo "id: $id\n";
        echo "data: $data\n\n";
        ob_flush();
        flush();
