你写的没有什么问题。

构造函数没有数据库名参数

是不是改成
protected $_host;
protected $_root;
protected $_password;
合适

直接用ADODB不好吗

构造函数只有3个参数没有数据库名字,没有选择到库,就查不出来数据,这个错误还是比较明显的

你的select方法没有使用mysql_fetch_assoc或者mysql_fetch_array获取数据,所以出不来结果。
应该这样

$result = mysql_query("SELECT * FROM users");$rows = array()while ($row = mysql_fetch_assoc($result)) {        $rows[] = $row;    }print_r($rows);
Copy after login
