How to modify only one value in thinkphp?

Database operation: modify a piece of data (thinkPHP)

The first method: the database contains an automatically growing field ID, and the ID is used as the where condition

<?php
class UserAction extends Action{
 public function updateUser(){
  $user = M(&#39;Userinfo&#39;);　　　　　　//实例化Model
  $data = array(&#39;ID&#39;=>5,&#39;username&#39;=>&#39;王美人&#39;,&#39;email&#39;=>&#39;meiren@163.com&#39;);//$data中包含有自动增长字段uid
  $res = $user->save($data);//调用Model下的save()函数进行数据的修改
  var_dump($res);
 }
}
?>

Second method: If there is no automatic growth of field ID in the database, you need to add where conditions

<?php
class UserAction extends Action{
 public function updateUser(){
  $user = M(&#39;userinfo&#39;);//实例化Model
  $data = array(&#39;username&#39;=>&#39;王美人&#39;,&#39;email&#39;=>&#39;mei@163.com&#39;);//$data中没有自动增长字段uid
  $res = $user->where(&#39;ID=5&#39;)->save($data);//需要增加where条件。调用Model下的save()函数进行数据的修改
  var_dump($res);//返回影响的行数
 }
}
?>
