facebook application php post to friends wall

问题:

I have a script that succesfully posts to my friend wall link and message, but when i turn on loop like this:

for ($i = $from; $i <= $to; $i++) {
        $sendTo = $userid[$i];

        echo '<p>sending user '.$i.'</p>';

        if($result = $facebook->api("/$sendTo/feed/",'post', $attachment))                        

                    {
            echo '<p>sended user '.$i.'</p>';
        } else {
            echo 'Oops something went wrong';
        }}           

it only posts 4 or 5 messages and then break. I suppos the problem is at facebook does not allowing many message to send in short time. How can i make some timeout function or something to post at least 100 messages? When i post only 5 messages i manage to post 100 messages 5 by 5, but i need to post 100 by 100. Can you help me please?

Thank you for your time and best regards

Posting on multiple user's walls like this is discouraged by Facebook. If you want to send multiple users a message, they recommend you use the requests dialog.

To delay sending requests, you could add a sleep(300) command after every 5 posts to give a 5 minute delay between postings. You'll have problems with script timeouts. Better would be to have your script create a cron job that posts 5 items at a time, and only runs every 5 minutes.

With either of these methods, you are spamming your users and you run a risk of your app getting disabled. See this Facebook Developers blog post for more info.
