GROUP a result of JOINS using QUERY BUILDER in Codeigniter - php

Question

I have the following function, the params are "asc,PV1"
public function get_products($order, $sku){
if(is_array($result) && $result['active']){
$id_emp = $result['id_emp'];
$mts = 'module_tienda_status';
$mtc = 'module_tienda_categories';
$mtp = 'module_tienda_productos';
$mtpt = 'module_tienda_product_type';
$mtpa = 'module_tienda_product_attribute';
$mta = 'module_tienda_attributes';
$mtao = 'module_tienda_attribute_option';
$mtpv = 'module_tienda_product_variation';
$mtpvo = 'module_tienda_product_variation_options';
$get = array(
$mtp.'.id',
$mtp.'.name',
$mtp.'.sku',
$mtp.'.desc_short',
$mtp.'.desc_long',
$mtp.'.id_category',
$mtp.'.price',
$mtp.'.id_status',
$mtp.'.inventory',
$mtp.'.imgs',
$mtp.'.qty',
$mtp.'.featured',
$mtc.'.name as cat_name',
$mtpt.'.id as type_id',
$mtpa.'.id_attribute',
$mtpa.'.id_option',
$mta.'.name as attr_name',
$mtao.'.option as opt_name',
$mtpv.'.inventory as var_inv',
$mtpv.'.qty as var_qty',
$mtpv.'.price as var_price',
$mtpvo.'.id_product_variation as var_id',
$mtpvo.'.id_attribute as var_attr',
$mtpvo.'.id_option as var_opt'
);
$this->db->select($get);
$this->db->from($mts);
$this->db->join($mtp, $mtp.'.id_status = '.$mts.'.id');
$this->db->join($mtc, $mtp.'.id_category = '.$mtc.'.id', 'left');
$this->db->join($mtpt, $mtp.'.id_product_type = '.$mtpt.'.id');
$this->db->join($mtpa, $mtpa.'.id_product = '.$mtp.'.id', 'left');
$this->db->join($mta, $mta.'.id = '.$mtpa.'.id_attribute', 'left');
$this->db->join($mtao, $mtao.'.id = '.$mtpa.'.id_option', 'left');
$this->db->join($mtpv, $mtp.'.id = '.$mtpv.'.id_product', 'left');
$this->db->join($mtpvo, $mtpv.'.id = '.$mtpvo.'.id_product_variation', 'left');
$this->db->where($mtp.'.id_emp', $id_emp);
if($sku != 'null'){
$this->db->where($mtp.'.sku', $sku);
}
if(!is_null($order)){
$this->db->order_by('module_tienda_productos.created', $order);
}
$query = $this->db->get()->result();
}else{
return $result;
}
}
the result is an array with 49 rows of the same product, the difference is that there are different attributes and variations, here is the example https://pastebin.com/3X4w6wEi
What i want is 1 single result with an array of attributes and 1 array of variations something like this (is a json, please decode it)
[{'id':'343','name':'Producto variable 1','sku':'PV1','desc_short':'<p><br></p>','desc_long':'<p><br></p>','id_category':null,'price':null,'id_status':'1','inventory':'0','imgs':null,'qty':'0','featured':'0','cat_name':null,'type_id':'2','attributes':[{'id_attribute':'49','attr_name':'Colors','opts':{'107':'Amarillo','110':'Celeste','121':'Rojo','122':'Azul'}},{'id_attribute':'57','attr_name':'Size','opts':{'112':'xs','113':'s','114':'n','116':'xl'}}],'variations':[{'var_id':'42','var_inv':'0','var_qty':'0','var_price':'0.00','opts':[{'id_attribute':'49','attr_name':'Colors','opts':{'107':'Amarillo','110':'Celeste','121':'Rojo','122':'Azul'}},{'id_attribute':'57','attr_name':'Size','opts':{'112':'xs'}}]}]}]
