//此处需要安装phpredis

$web_info= array(
'uid' => '123456',
'username' => '123',
'content' =>'123'

//将数组转成json来存储
$list = json_encode($web_info);
//lpush向KEY对应的头部添加一个字符串元素
$redis->lpush('weibo_lists',$list);
$redis->close();
///var_dump(json_encode($web_info));
var_dump($list);

//创建一个PDO数据库链接 data.php
class qq{
 public function post($uid='',$username='',$content=''){
  try{
   $dsn = "mysql:host;dbname=localhost;dbname=test";
   $db = new PDO($dsn,'root','root');

   $sql ="insert into test(uid,username,content)values('$uid','$username','$content')";
   $db->exec($sql);
  }catch(PDOException $e){
   $e->getMessage();

//处理redis数据库的数据 并把数据放到MYSQL数据库中

$qq = new qq();
$redis = new Redis();
$redis->connect('127.0.0.1', 6379);
//返回的列表的大小.如果列表不存在或为空,该命令返回0.如果该键不是列表,该命令返回FALSE

 //从LIST头部删除并返回删除数据
