php mysql 救命呀！！！！
thinkphp框架
  public function select() {
  $db_dsn = mysql://root:guozhixin@localhost:3306/my_table;
  $db = new db($db_dsn);
  echo $db->execute(select * from think_person);
  }

数据库设置全对，怎么就是访问以后是一片空白呢？有人能帮帮我吗？
------解决方案--------------------
echo $db->execute(select * from think_person);
你改成： dump($db->execute(select * from think_person)); 试试。
＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋
如下为数据库配置：
//'配置项'=>'配置值'
'db_type'=>'mysql',
'db_host'=>'localhost',
'db_name'=>'test',
'db_user'=>'root',
'db_pwd'=>'123456',
'db_port'=>'3306',
'db_prefix'=>'think_',
写一个action:
function get_data()
{
$db=m('user');
dump($db->where('id=1')->select());
}
