php thinkphp3.2.3怎么获取数据库一条数据

并再模板中输出

Answer 1

$db = M('table'); //表名
$where = array( //条件数组

'id' => 2,

);

$rs = $db->where($where)->select(); //查询， 用find()只能查出一条数据，select()多条

$this->assign('datalist',$rs); //模板赋值
$this->display();//输出到模板

Answer 2

$ret = M('表名')->where('条件')->field(' 要查的字段')->find();
