laravel查询结果集转成数组

toArray 方法将集合转换成 PHP 数组。如果集合的值是 Eloquent 模型，那也会被转换成数组

$collection = collect(['name' => 'Desk', 'price' => 200]);

$collection->toArray();

DB:table()->get(); 的返回值怎么转换为数组？

$objectData =  DB::table('spaces')->get();

//返回的是 object(Illuminate\Support\Collection)

$arrayData = DB::table('spaces')->get()

 ->map(function ($value) {return (array)$value;})

 ->toArray();

//返回的是 array

public function objectToArray($object) {

    //先编码成json字符串，再解码成数组

    return json_decode(json_encode($object), true);

}

DB::table('spaces')->first();

//返回值是  object(stdClass)

$arrayData = get_object_vars($objectData);

//返回值是array
