Answer 1

Take a look at the docs here, scroll down to "Using Where In With An Array":

http://four.laravel.com/docs/queries

The whereIn method takes an array, so pass in $var directly, no need to implode.

->whereIn('device_id', $var)

Answer 2

Laravel is using PDO library. Sadly, binding with PDO doesn't work with WHERE IN. You can read about it here.

So what you have to do is to put prepared string in your query like this:

"(...)
    WHERE device_id IN (".array(implode(',', $var)).")
    (...)"

Answer 3

"(...)
    WHERE device_id IN (".implode(',', $var).")
    (...)"
