<code> ThinkPHP find方法 查询一条数据记录 find() ThinkPHP find() 方法是和 select() 用法类似的一个方法,不同之处 find() 查询出来的始终只有一条数据,即系统自动加上了 LIMIT 1 限制。 当确认查询的数据记录只能是一条记录时,建议使用 find() 方法查询,如用户登录账号检测: public function chekUser(){ header("Content-Type:text/html; charset=utf-8"); $Dao = M("User"); // 构造查询条件 $condition['username'] = 'Admin'; $condition['password'] = MD5('123456'); // 查询数据 $list = $Dao->where($condition)->find(); if($list){ echo '账号正确'; }else{ echo '账号/密码错误'; } } 与 select() 的另一个不同之处在于,find() 返回的是一个一维数组,可以在模板里直接输出数组单元的值而无需使用 volist 等标签循环输出: {$list['username']} find() 主键查询 当 find() 查询的条件参数为表主键时,可以直接将参数写入方法内,如: $Dao = M("User"); $list = $Dao->find(1); user 表主键为 uid,该例子将查询 uid=1 的数据,这是 ActiveRecords 模式实现之一,简洁直观。 </code>
For example: $list = $Base->where("id='".$id."'")->select();
echo echo $list['title'];
Extract array:
$list = $Base->where("id='".$id."'")->select();
Change to
$list = $Base->where("id='".$id."'")->find();
Select found out that it is a two-dimensional array
If you are sure that there is only one record in the result, please use find. Of course, you are right to use select, but it feels like taking off your pants and farting. If you use select, you have to echo $list[0]['title'];
