Question

我有两个while循环来获取两个不同的值作为数组，它们被称为标题和menu.In我希望像菜单数组值的结果在标题数组中。

这是我的代码：

        $heading = array();
        $menu = array();
        $stmt_heading = $this->conn->prepare("SELECT main_heading_name,sub_heading_name FROM `selected_food_main_sub_heading` WHERE branch_id = ? AND brand_id = ? AND business_id = ? ");
        $stmt_heading->bind_param("iii",  $branch_id, $brand_id,$business_id);
        $stmt_heading->execute();
        $result = $stmt_heading->get_result();
        while ($row = $result->fetch_assoc()) 
        {
            array_push($heading, $row);
            $stmt_menu = $this->conn->prepare("SELECT * FROM `menu_deatils` WHERE main_heading_name = ? AND sub_heading_name = ? ");
            $stmt_menu->bind_param("ss",  $row['main_heading_name'], $row['sub_heading_name']);
            $stmt_menu->execute();
            $result_menu = $stmt_menu->get_result();
            while ($row_menu = $result_menu->fetch_assoc()) 
            {
                array_push($menu, $row_menu);
            }
            $data['menu_list'] = $menu;
            array_push($heading, $data);
            $stmt_menu->close();

        }
        return $heading;

标题数组值：

[
      {
        "main_heading_name": "Quick Bites",
        "sub_heading_name": "Biryani & Rice"
      },
      {
        "main_heading_name": "Bites",
        "sub_heading_name": "Biryani & Rice"
      }
]

菜单数组值：

{
    "menu_list": [{
            "main_heading_name": "Quick Bites",
            "sub_heading_name": "Biryani & Rice"
        },
        {
            "main_heading_name": "Quick Bites",
            "sub_heading_name": "Biryani & Rice"
        }
    ]
}

我想要一个结果：

  [
      {
            "main_heading_name": "Quick Bites",
            "sub_heading_name": "Biryani & Rice",
            "menu_list": [{
                    "main_heading_name": "Quick Bites",
                    "sub_heading_name": "Biryani & Rice"
                },
                {
                    "main_heading_name": "Quick Bites",
                    "sub_heading_name": "Biryani & Rice"
                }
            ]
        },
        {
            "main_heading_name": "Bites",
            "sub_heading_name": "Biryani & Rice",
            "menu_list": [{
                    "main_heading_name": "Quick Bites",
                    "sub_heading_name": "Biryani & Rice"
                },
                {
                    "main_heading_name": "Quick Bites",
                    "sub_heading_name": "Biryani & Rice"
                }
            ]
        }
    ]

怎么办？提前谢谢！

Answer 1

$FullArray1 = $menu + $heading;
$FullArray2 = array_merge($menu, $heading);

这两个都会产生预期的结果。

array_push($menu, $heading);

如何将第二个数组推入php
