Answer 1

$old_data = $old['body'];
foreach($old_data as $v){
    if (!array_key_exists($v['category_id'],$new)){
        $new[$v['category_id']]['cate_id']  = $v['category_id'];
        $new[$v['category_id']]['cate_name']= $v['c_name'];
    }
    
    $new[$v['category_id']]['boby'][] = $v;
    
}

Answer 2

$new_data   = [];  // 收集分类相同的数据
        $cate_goods = [];  // 收集分类和商品信息--最终数据
        $cate       = [];  // 拼接分类 将分类单独提出来
        if ( $result )
        {

            foreach ( $result as $key => $value ) 
            {
                $value['img_url'] = $this->img_url.$value['img_url'];
                $new_data[$value['category_id']][]  = $value;
            }

            // 将分类名称单独提出来
            if ( $new_data )
            {
                foreach ( $new_data as $k => $v ) 
                {
                    if ( $v )
                    {
                        $cate['cate_id']   = $v[0]['category_id'];
                        $cate['cate_name'] = $v[0]['c_name'];
                        $cate['info']      = $v;

                        $cate_goods[] = $cate;
                    }
                }
            }
        }
