php - How to write nested joins with Laravel Query builder? -

i have sql query next join order (two join's nested in left join):

select * mytable left join table1   join table2 on table2.id = table1.document_id   join table3 on table3.content_id = table2.id on table1.link_id = mytable.link_id 

how write query laravel query builder?

my way:

$query = mytable::select('*')     ->leftjoin(db::raw('table1         join table2 on table2.id = table1.document_id         join table3 on table3.content_id = table2.id     '),      'table1.link_id', '=', 'mytable.link_id'); 

it works, way without db::raw()? maybe $join->nest()?

the joins aren't nested being used limit number of viable records.

$query = mytable::select('*') ->leftjoin('table1', 'table1.link_id', '=', 'mytable.link_id') ->join('table2', 'table2.id', '=', 'table1.document_id') ->join('table3 ', 'table3.content_id', '=', 'table2.id');
