Make Money With Laravel Query Builder

I have a connection in laravel 5.1 and it works great, but I am returning an array with each result of my connection. Is there a way to return results with nested array join results inside my main select query, or should it be something I do in PHP after getting the results?

$single = $this->db->table($this->table)
            ->leftJoin("ootd_clothing", "ootd_clothing.ootd_id", "=" ,"$this->table.id")
            ->leftJoin("users", "users.id", "=", "$this->table.user_id")
            ->where("$this->table.slug", "=", $slug)
            ->select("$this->table.name AS ootd_name", "$this->table.image_path", "$this->table.slug", "$this->table.description", "users.name AS user_name", "ootd_clothing.item", "ootd_clothing.brand")
            ->get();

      

        
        
        
      

    

The result I am getting:

array:5 [▼
0 => {#158 ▶}
1 => {#159 ▶}
2 => {#160 ▶}
3 => {#161 ▶}
4 => {#162 ▶}
]

      

        
        
        
      

    

The result that I would like:

array:1 [
  'id': 1, 
  'joinResults':array:5 [▼
     0 => {#158 ▶}
     1 => {#159 ▶}
     2 => {#160 ▶}
     3 => {#161 ▶}
     4 => {#162 ▶}
 ]
]
