Laravel return value

First understand a few concepts:

• StdClass target => base objects

• Eloquent Object Model (Model object) => class object associated with the model

• Eloquent set => be understood as a simple array of objects, in which each element is an Object Model

DB Facades

1, $users = DB::table('users')->get(); 返回值：数组结果，其中每一个结果都是 StdClass

2, $user = DB::table('users')->first(); 返回值：单个 StdClass 实例

 

Eloquent

1, $user = User::first(); 返回值：Eloquent 对象

2, $user = User::find(); 返回值：Eloquent 对象

3, $users = User::get(); 返回值：Eloquent 集合

4, $users = User::all(); 返回值：Eloquent 集合

5, $user = User::create($data); 返回值：Eloquent 对象

6,  $user = new User();
    $user->name = "admin"
    $user->save();

    返回值：Eloquent 对象

7, $result = User::insert($data); 返回值：bool

8, $result = $user->delete(); 返回值：bool

9, $count = User::destroy([1, 2]); 返回值：删除记录数

10, $count = User::where('id', '>', 1)->delete(); 返回值：删除记录数

11, $count = User::where('id', '>', 10)->update(['status' => 1]);返回值：更新记录数

12, $count = User::where('id', '>', 10)->increment('age', 1); 返回值：更新记录数
