Php 用于与pdo进行数据库连接的类 `

分析错误：语法错误，意外的“public”（T_public），应为“，”或“；”在第7行的C:\xampp\htdocs\lr\lib\Database.php中

缺少分号：

<?php
class Database{
    private $hostdb="localhost";
    private $userdb = "root";
    private $passdb = "";
    private $namedb = "database"
    public $pdo;

    public function __construct(){
        if(!isset($this->pdo)) {
            try{
                $link = new PDO("mysql:host=".$this->hostdb.";dbname=".$this->namedb, $this->userdb, $this->passdb);
                $link->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
                $link->exec("SET CHARACTER SET utf8");
                $this->pdo = $link;
            }catch(PDOException $e){
                die("failed to connect with database".$e->getMessage());
            }   

        }
    }
}

private$namedb=“数据库”//
private $namedb = "database" ; // <--
