我的 sql 表在行中包含脱机访问令牌包含 id 列和访问令牌我想编辑代码以运行 $output 为从 1 到 50 的 ids 然后下一个按钮运行下一个 50 直到全部完成而不是一次全部运行

   <?php

require './config.php';
require './facebook.php';

//connect to mysql database
mysql_connect($db_host, $db_username, $db_password);
mysql_select_db($db_name);
mysql_query("SET NAMES utf8");

//Create facebook application instance.
$facebook = new Facebook(array(
  'appId'  => $fb_app_id,
  'secret' => $fb_secret
));

$output = '';

//if form below is posted- 
//lets try to send wallposts to users walls, 
//which have given us a access_token for that
if(isset($_POST['send_messages'])){

    //default message/post
    $msg =  array(
        'message' => 'date: ' . date('Y-m-d') . ' time: ' . date('H:i')
    );

    //construct the message/post by posted data
    if(isset($_POST['message'])){
        $msg['message'] = $_POST['message'];
    }
    if(isset($_POST['url']) && $_POST['url'] != 'http://'){
        $msg['link'] = $_POST['url'];
    }
    if(isset($_POST['picture_url']) && $_POST['picture_url'] != ''){
        $msg['picture'] = $_POST['picture_url'];
    }

    //get users and try posting our message/post
    $result = mysql_query("
        SELECT
            *
        FROM
            offline_access_users
    ");

    if($result){
        while($row = mysql_fetch_array($result, MYSQL_ASSOC)){
            $msg['access_token'] = $row['access_token'];
            try {
                $facebook->api('/me/feed', 'POST', $msg);
                $output .= "<p>Posting message on '". $row['name'] . "' wall success</p>";
            } catch (FacebookApiException $e) {
                $output .= "<p>Posting message on '". $row['name'] . "' wall failed</p>";
            }
        }
    }
}

奖励：使用PDO而不是 mysql_* 函数。
