Issue in php json formatting - php

Question

I am currently stuck in json formatting for php. I have given my outputted json below. What I need to do is to make the format of the current json to the desired one. I am missing the arrays in the JSON format. Can anyone help me on this.
My code to print the json output is below:
$menuHead=array();
$i=0;
foreach($res as $key => $value){
$i=$key+1;
//$menuHead[$i]['menuHead']=$value['category'];
if(isset($menuHead[$key]['menuHead'])){
if($menuHead[$key]['menuHead']==$value['category']){
$menuHead[$key]['data'][$i]['itemName']=$value['sub_category'];
$menuHead[$key]['data'][$i]['price']=$value['price'];
$menuHead[$key]['data'][$i]['description']=$value['description'];
$menuHead[$key]['data'][$i]['itemId']=$value['id'];
$menuHead[$key]['data'][$i]['customizable']=$value['customizable'];
}else{
$menuHead[$i]['menuHead']=$value['category'];
$menuHead[$i]['data'][$i]['itemName']=$value['sub_category'];
$menuHead[$i]['data'][$i]['price']=$value['price'];
$menuHead[$i]['data'][$i]['description']=$value['description'];
$menuHead[$i]['data'][$i]['itemId']=$value['id'];
$menuHead[$i]['data'][$i]['customizable']=$value['customizable'];
}
}else{
$menuHead[$i]['menuHead']=$value['category'];
$menuHead[$i]['data'][$i]['itemName']=$value['sub_category'];
$menuHead[$i]['data'][$i]['price']=$value['price'];
$menuHead[$i]['data'][$i]['description']=$value['description'];
$menuHead[$i]['data'][$i]['itemId']=$value['id'];
$menuHead[$i]['data'][$i]['customizable']=$value['customizable'];
}
}
$final['MenuList']=$menuHead;
echo json_encode($final);
Current format:
{
"MenuList": {
"1": {
"menuHead": "Main Course",
"data": {
"1": {
"itemName": "Chicken Thai Curry",
"price": "599",
"description": "",
"itemId": "67",
"customizable": "1"
}
}
},
"2": {
"menuHead": "Refreshments",
"data": {
"2": {
"itemName": "Kingfisher Premium",
"price": "999",
"description": "Kingfisher beer",
"itemId": "69",
"customizable": "1"
},
"3": {
"itemName": "Mocktail",
"price": "999",
"description": "",
"itemId": "68",
"customizable": "1"
}
}
},
"4": {
"menuHead": "Rice biriyani",
"data": {
"4": {
"itemName": "Dal makni risotto",
"price": "499",
"description": "Dal makhni risotto",
"itemId": "66",
"customizable": "1"
}
}
}
}
}
Desired Format:
{
"menuList": [
{
"menuHead": "In Steamer (Momos)",
"data": [
{
"itemName": "Tandoori Momo",
"description": "",
"price": "150",
"itemId": "16",
"customizable": "0"
},
{
"itemName": "Fried Momo Pork",
"price": "100",
"description": "",
"itemId": "15",
"customizable": "0"
}
]
},
{
"itemName": "Rice and Noodles",
"data": [
{
"sub_category": "Tandoori Momo",
"description": "",
"price": "150",
"itemId": "16",
"customizable": "0"
},
{
"itemName": "Fried Momo Pork",
"price": "100",
"description": "",
"itemId": "15",
"customizable": "0"
}
]
}
]
}
Raw response is below:
array(4) { [0]=> array(7) { ["id"]=> string(2) "67" ["restaurant_id"]=> string(1) "5" ["category"]=> string(11) "Main Course" ["sub_category"]=> string(18) "Chicken Thai Curry" ["price"]=> string(3) "599" ["description"]=> string(0) "" ["customizable"]=> string(1) "1" } [1]=> array(7) { ["id"]=> string(2) "69" ["restaurant_id"]=> string(1) "5" ["category"]=> string(12) "Refreshments" ["sub_category"]=> string(18) "Kingfisher Premium" ["price"]=> string(3) "999" ["description"]=> string(15) "Kingfisher beer" ["customizable"]=> string(1) "1" } [2]=> array(7) { ["id"]=> string(2) "68" ["restaurant_id"]=> string(1) "5" ["category"]=> string(12) "Refreshments" ["sub_category"]=> string(8) "Mocktail" ["price"]=> string(3) "999" ["description"]=> string(0) "" ["customizable"]=> string(1) "1" } [3]=> array(7) { ["id"]=> string(2) "66" ["restaurant_id"]=> string(1) "5" ["category"]=> string(13) "Rice biriyani" ["sub_category"]=> string(17) "Dal makni risotto" ["price"]=> string(3) "499" ["description"]=> string(18) "Dal makhni risotto" ["customizable"]=> string(1) "1" } }

Answer 1

If you want a javascript compatible array, the index must start at 0. The easiest way to do that, is to use array_values():
$final['MenuList'] = array_values($menuHead);

Answer 2

The problem is that when your adding the data items, you need to add them without specific keys, as you add them with $i as in...
$menuHead[$key]['data'][$i]['itemName']=$value['sub_category'];
This will stop them being a normal array as you want it to be. For json_encode() an array must start at 0 and be sequential for it to be an array.
Instead create them in one go and add them to the end of the existing data using []...
$menuHead[$key]['data'][] = ['itemName' =>$value['sub_category'],
'price'=> $value['price'],
'description'=>$value['description'],
'itemId'=>$value['id'],
'customizable'=>$value['customizable']];
This needs to be done with each set of similar code, which includes the overall array itself, this can be done using
$final['MenuList'] = array_values($menuHead);
To try and fix the data you already have, which means no changes except adding the following code...
foreach ( $menuHead as $menu ) {
$menu['data'] = array_values($menu['data']);
}
$final['MenuList'] = array_values($menuHead);

Answer 3

Use array_values();
I fixed your code, it should work
$menuHead=array();
$i=0;
foreach($res as $key => $value){
$i=$key+1;
//$menuHead[$i]['menuHead']=$value['category'];
if(isset($menuHead[$key]['menuHead'])){
if($menuHead[$key]['menuHead']==$value['category']){
$menuHead[$key]['data'][$i]['itemName']=$value['sub_category'];
$menuHead[$key]['data'][$i]['price']=$value['price'];
$menuHead[$key]['data'][$i]['description']=$value['description'];
$menuHead[$key]['data'][$i]['itemId']=$value['id'];
$menuHead[$key]['data'][$i]['customizable']=$value['customizable'];
}else{
$menuHead[$i]['menuHead']=$value['category'];
$menuHead[$i]['data'][$i]['itemName']=$value['sub_category'];
$menuHead[$i]['data'][$i]['price']=$value['price'];
$menuHead[$i]['data'][$i]['description']=$value['description'];
$menuHead[$i]['data'][$i]['itemId']=$value['id'];
$menuHead[$i]['data'][$i]['customizable']=$value['customizable'];
}
}else{
$menuHead[$i]['menuHead']=$value['category'];
$menuHead[$i]['data'][$i]['itemName']=$value['sub_category'];
$menuHead[$i]['data'][$i]['price']=$value['price'];
$menuHead[$i]['data'][$i]['description']=$value['description'];
$menuHead[$i]['data'][$i]['itemId']=$value['id'];
$menuHead[$i]['data'][$i]['customizable']=$value['customizable'];
}
}
// i'am use array_values()
$final['MenuList']= array_values($menuHead);
echo json_encode($final);
