        foreach ($comments as $i)
        {
            $comment_id[] = $i->id;

        for($i=0;$i<count($comments);$i++)
        {
            Comment::find($comment_id[$i])->delete();
        }
    }
    elseif (count($comments)==1)
    {
        $comments->delete();
    }

Since each Eloquent model serves as a query builder, try this, all in one line:

Comment::where('post_id',$id)->delete();

Tested in tinker, works as expected, returns count of deleted rows.
