PHP json_encode string key as array - php

i write a api for my games to get achievements and so on. i load the data from a webserver into unity c# over a www request. i need a array from php which contain achievements and more data. the problem is, the result is this
[
{"ID":"1",
"gameID":"1",
"name":"achv1",
"neededvalue":"50",
"player_achievements":{
"ID":"8",
"achievementID":"1",
"playerID":"9",
"value":"",
"completed":""
}
},
{"ID":"2",
"gameID": "1",
"name":"achv2",
"neededvalue":"100",
"player_achievements":{
"ID":"9",
"achievementID":"2",
"playerID":"9",
"value":"","completed":""
}
}
]
the player_achievements is a child array of the head array and i need the square_brackets around the player_achievements [] because untity c# cannot convert it to an object. i search hours for finding a solution but nobody explain how. i found this link but this is not a option for me. i want the string keys and not numbers. give it a way to use the string keys as array and not as object ?
i need it like so:
[
{ "ID":"1",
"gameID":"1",
"name":"achv1",
"neededvalue":"50",
"player_achievements":[
{ "ID":"8",
"achievementID":"1",
"playerID":"9",
"value":"",
"completed":""
}
]
},
{
"ID":"2",
"gameID":"1",
"name":"achv2",
"neededvalue":"100",
"player_achievements":[
{ "ID":"9",
"achievementID":"2",
"playerID":"9",
"value":"",
"completed":""
}
]
}
]

If I am reading your question correctly, you need to make the player_achievements element an array containing the original value of that element.
<?php
$json = <<<END
[
{"ID":"1",
"gameID":"1",
"name":"achv1",
"neededvalue":"50",
"player_achievements":{
"ID":"8",
"achievementID":"1",
"playerID":"9",
"value":"",
"completed":""
}
},
{"ID":"2",
"gameID": "1",
"name":"achv2",
"neededvalue":"100",
"player_achievements":{
"ID":"9",
"achievementID":"2",
"playerID":"9",
"value":"","completed":""
}
}
]
END;
$data = json_decode($json, true);
for($i=0;$i<sizeof($data);$i++)
{
$data[$i]['player_achievements'] = [$data[$i]['player_achievements']];
}
echo json_encode($data);
This produces a structure like the one you say you need.
[
{
"ID": "1",
"gameID": "1",
"name": "achv1",
"neededvalue": "50",
"player_achievements": [
{
"ID": "8",
"achievementID": "1",
"playerID": "9",
"value": "",
"completed": ""
}
]
},
{
"ID": "2",
"gameID": "1",
"name": "achv2",
"neededvalue": "100",
"player_achievements": [
{
"ID": "9",
"achievementID": "2",
"playerID": "9",
"value": "",
"completed": ""
}
]
}
]

I found an answer, I add a zero before the child element as key of array.

Rewrite json in loop

I have an array, which i wrote like a table for more reability.
[{
"id": "1",
"title": "boune",
"value": "3"
}, {
"id": "2",
"title": "check",
"value": "4"
}, {
"id": "3",
"title": "boune",
"value": "5"
}]
As the result of what i want to see is this json, where 'value' of identical 'titles' united inside [] brackets. I am very newbie in php. I undestand that i need for loop to sort query result, but can`t heck...Cant even put my mind to it...
[{
"id":"1",
"title": "boune",
"value": [3, 5]
}]
<?php
$json = '[{"id":"1","title":"boune","value":"3"},{"id":"2","title":"check","value":"4"},{"id":"3","title":"boune","value":"5"}]';
$json_data = json_decode($json,true);
function accumulateValuesByTitle($json_data){
$hash = [];
foreach($json_data as $each_record){
if(isset($hash[$each_record['title']])){
$hash[$each_record['title']]['value'][] = $each_record['value'];
if($hash[$each_record['title']]['id'] > $each_record['id']){
$hash[$each_record['title']]['id'] = $each_record['id'];
}
}else{
$hash[$each_record['title']] = $each_record;
$hash[$each_record['title']]['value'] = [$hash[$each_record['title']]['value']];
}
}
return array_values($hash);
}
$modified_data = accumulateValuesByTitle($json_data);
echo json_encode($modified_data);

Easiest way of accessing deep-nested value in json response?

I have the following response (I cut the extra short):
{
"meta": {
"current_page": "1",
"last_page": "1",
"per_page": "15",
"total": "1",
"from": "1",
"to": "1"
},
"Products": [
{
"archived": "0",
"committed_stock": "0",
"created_at": "2015-05-10T17:39:53+00:00",
"deleted": "0",
"description": "desc",
"id": "43061710",
"links": {
"Users": [
{
"id": "107534",
"type": "created_by"
}
],
"Attributes": [
{
"id": "31538870"
}
]
}
}
]
}
Everytime I get this response, there will only be one item in "Attributes." What is the easiest way of grabbing this value? So far I have this:
$json = json_decode($json_data);
$json = json_decode($json_data, true);
echo $json["Products"][0]["links"]["Attributes"][0]["id"];
try this:
var_dump( $json->Products[0]->links->Attributes);
the object field could be ether also an object, or an array:
refer to field: $object->object
refer to array's i cell: $object->array[i]
P.S.
please edit the json, it's missing it's end...

fetch values from array within an array

I have a multidimensional array, i wish to extract each value from this array.
The array is stored in $data.
{"success":true,"categories":
[
{"
category_id":"C1",
"parent_id":"P1",
"name":"N1",
"categories":
[
{
"category_id":"C11",
"parent_id":"P11",
"name":"N11",
},
{
"category_id":"C12",
"parent_id":"P12",
"name":"N12",
},
],
"status":"1"
},
{
category_id":"C2",
"parent_id":"P2",
"name":"N2",
"categories":
[
{
"category_id":"C21",
"parent_id":"P21",
"name":"N21",
[
{
"category_id":"C22",
"parent_id":"P23",
"name":"N24",
}
],
"status":"2"
}
],
"status":"3"
},
]
}
I tried using
$total = $data['categories']['category_id'];
to fetch value C11
but wasn't able to do so.
can anyone tell how i can fetch all the data especially C22
You have to first use json_decode.
$array = json_decode($data, true);
Then you can access the array as you have stated.
Or loop throught the categories:
if (!empty($array)) {
foreach ($array['categories'] as $category) {
echo $category['id'];
}
}
You may have to do this recursively to loop through the categories within the categories. But it depends completely what you want to achieve. A nested loop could do the job if it is always just one level deep.
EDIT
The JSON you have provided is not quite right, I have given a corrected one below:
{
"success": true,
"categories": [
{
"category_id": "C1",
"parent_id": "P1",
"name": "N1",
"categories": [
{
"category_id": "C11",
"parent_id": "P11",
"name": "N11"
},
{
"category_id": "C12",
"parent_id": "P12",
"name": "N12"
}
],
"status": "1"
},
{
"category_id": "C2",
"parent_id": "P2",
"name": "N2",
"categories": [
{
"category_id": "C21",
"parent_id": "P21",
"name": "N21",
"categories": [
{
"category_id": "C22",
"parent_id": "P23",
"name": "N24"
}
],
"status": "2"
}
],
"status": "3"
}
]
}
There were a few trailing commas and missing quote marks.
The data is not in PHP array, its a JSON array. You have to decode it, by using json_decode() function.
That's JSON, not php multidimensional array. You can use json_decode function to read through it.

PHP getting values from nested json

I have this json listed below. I was using json_decode to get some of the values. Such as getting the id value:
$decoded_array = json_decode($result, true);
foreach($decoded_array['issue'] as $issues ){
$value[] = $issues["id"];
This method is working for getting the id value, however, I want to get the emailAddress values for both Bob and John. I believe you can get a single value by doing this:
$value[] = $issues["fields"][people][0][emailAddress];
Is it possible to get both email addresses in an efficient manner?
Edited --------
How would you get data with an expanded dataset? Example:
{
"startAt": 0,
"issue": [
{
"id": "51526",
"fields": {
"people": [
{
"name": "bob",
"emailAddress": "bob#gmail.com",
"displayName": "Bob Smith",
},
{
"name": "john",
"emailAddress": "john#gmail.com",
"displayName": "John Smith",
}
],
"skill": {
"name": "artist",
"id": "1"
}
}
},
{
"id": "2005",
"fields": {
"people": [
{
"name": "jake",
"emailAddress": "jake#gmail.com",
"displayName": "Jake Smith",
},
{
"name": "frank",
"emailAddress": "frank#gmail.com",
"displayName": "Frank Smith",
}
],
"skill": {
"name": "writer",
"id": "2"
}
}
}
]
}
I only want to extract the email addresses from both "fields". Is there an easy way to loop through all the "fields" to get "emailAddress" data?
You need to delve deeper into the array.
foreach ($decoded_array['issue'][0]['fields']['people'] as $person) {
echo $person['emailAddress'];
}

FuelPHP + JSON + Ajax

For example, when I use Model_Trabalhos::query()->related('categoria'), I Get a normal JSON like this:
{
"id": "1",
"categoria_id": "2",
"empresa": "Veja",
"nome": "Veja",
"thumb_pequena": "jobs/digital/veja/thumb.jpg",
"thumb_grande": "jobs/digital/veja/thumb_grande.jpg",
"destaque": "0",
"categoria": {
"id": "2",
"titulo": "Digital"
},
"imagens": {
"1": {
"id": "1",
"url": "jobs/digital/veja/1.png",
"legenda": "",
"job_id": "1"
},
"2": {
"id": "2",
"url": "jobs/digital/veja/2.png",
"legenda": "",
"job_id": "1"
}
}
}
instead, I wanted to receive back this:
[
{
"id": "3",
"categoria_id": "2",
"empresa": "Valor Econômico",
"nome": "Novo Site",
"thumb_pequena": "jobs/digital/valor-economico/thumb.jpg",
"thumb_grande": "jobs/digital/valor-economico/thumb_grande.jpg",
"destaque": "1",
"categoria": {
"id": "2",
"titulo": "Digital"
},
"imagens": [
{
"id": "3",
"url": "jobs/digital/valor-economico/1.png",
"legenda": "",
"job_id": "3"
}
]
}
]
You see? In the second case, it's wrapped in an array, and I wanted to know if there's a function in FuelPHP native that wrap the content to be ordered.
I'm in trouble... I'm using FuelPHP + ORM to get all my records from a database and generating a JSON to use with JavaScript and Ajax, but in Chrome, the JSON is not following the order by defined, is there any workaround for this problem?
If you're wanting your information in a certain way you could follow that query with a foreach loop that would add them to an array of arrays (translated to an array of JSON objects) once converted to JSON.
$query = Model_Trabalhos::query()->related('categoria')
$categories = array();
foreach ($query as $category) {
$categories[] = array(
'id' => $category->id,
...
);
}
return $categories;
It's an old question, but i had the same problem now and colud resolve like the answer that i posted in https://stackoverflow.com/a/34242106/5670195.
In case it is a function that converts into simple array, the objects returned as the relationship of ORM.
