Access variable of stdClass Object

Question

I am using Laravel with a select statement to select the row with the highest id like this:

$user_id = DB::connection('mysql2')->select('SELECT MAX(id) FROM users')[0];

This returns an array with an object that looks like this:

stdClass Object ( [MAX(id)] => 11 ) 1

I have tried $object->MAX(id) and $object['MAX(id)'] but it does not seem to work.

Answer 1

Why are you using the RAW queries when you can utilise the power of Eloquent. You can do this

User::max('id')

This code will return the maximum value of 'id' column in 'users' table. Given that you have set up your model User . You can read more about Eloquent max at given docs link.

Answer 2

可以使用大括号访问通常不允许使用字符的动态属性，如下所示：

$object->{"MAX(id)"}
