php getting value from object [duplicate] - php

This question already has an answer here:
How to extract and access data from JSON with PHP?
(1 answer)
Closed 4 years ago.
I've got basic array from my api:
{ "title": "offer title", "body": "offer body",
"specialities": { "lang": "en", "id": "1", "icon": "0",
"name": "speciality name 1" }, "region": "region1" }
I want to get id value from request for my php variable lets say: $idVariable. How can I do it?
I tried something like:
$idVariable = $request->specialities[0]->id
but it seems not working. What is the right way?
Then how should I work with the arrays of object in this case:
{ "title": "offer title", "body": "offer body",
"specialities": [
{ "lang": "en", "id": "1", "icon": "0", "name": "speciality name 1" },
{ "lang": "en", "id": "2", "icon": "0", "name": "speciality name 2" },
{ "lang": "en", "id": "2", "icon": "0", "name": "speciality name 3" },
etc...], "region": "region1" }
To get id's of every object in specialities array? I know that it could be a duplicate question, but I ask for just a basic example.
I tried to use json decode like below:
json_decode($request->get('specialties'))->id
edit:
The almost-right way to do it is to decode json file first:
$data = json_decode($request);
and then get the right property from the array:
$id = $data['specialities'][0]['id'];
the problem now is that id is a string not an integer and by simply using:
$int_id = intval($id)
I've got $int_id = 0 instead of 1,2,3 etc

You are getting a response from API in JSON you should use json_decode() and then use the data. Try this code.
$json = '{ "title": "offer title", "body": "offer body",
"specialities": { "lang": "en", "id": "1", "icon": "0",
"name": "speciality name 1" }, "region": "region1" }';
$data = json_decode($json);
echo $data->specialities->id;

Kendo UI Gantt chart not processing JSON

I've tried to switch the datasource of the Kendo UI Gantt example inside PHP. I have mapped the schema with what is being returned, but I just get a blank gantt chart with one heading - "undefined".
{
"1": {
"id": "1",
"orderId": "1",
"title": "TESTER1",
"start": "\/new Date('2016-01-01 09:00:00')\/",
"end": "\/new Date('2016-02-01 00:00:00')\/",
"project": "1",
"client": "4218",
"parent": "0",
"percentComplete": "10.11"
},
"2": {
"id": "2",
"orderId": "2",
"title": "TESTER2",
"start": "\/new Date('2016-01-03 09:00:00')\/",
"end": "\/new Date('2016-02-01 00:00:00')\/",
"project": "1",
"client": "4218",
"parent": "0",
"percentComplete": "50.00"
}
}
Above is the JSON being sent back to Kendo, but it doesn't render.
Found the solution:
I type casted the integers, set parents to null rather than zero (0) and converted dates into milliseconds in the PHP layer before putting through to Kendo. I also removed the keys which resulted in the below JSON to be created. This solved my rendering problem.
[{
"id": 1,
"orderId": 1,
"title": "TESTER1",
"start": "\/Date(1463126400000)\/",
"end": "\/Date(1463958000000)\/",
"project": 1,
"client": 4218,
"parent": null,
"percentComplete": 10
}, {
"id": 2,
"orderId": 2,
"title": "TESTER2",
"start": "\/Date(1463990400000)\/",
"end": "\/Date(1464130800000)\/",
"project": 1,
"client": 4218,
"parent": null,
"percentComplete": 50
}]

PHP loop through data from JSON string

I want to get ItemCategory->id's for each Item->id
How can I do it in the best way?
Here is a part of JSON data item
"6": {
"Item": {
"id": "6",
"name": "test",
"description": "description",
},
"ItemThumbnail": null,
"ItemCategory": {
"3": {
"id": "3",
"name": "name",
"status": "active",
"date_created": "2015-07-07 11:23:52",
"date_updated": "0000-00-00 00:00:00",
},
"4": {
"id": "4",
"name": "name",
"status": "active",
"date_created": "2015-07-07 11:23:52",
"date_updated": "0000-00-00 00:00:00",
}
},
"ItemGroup": []
},
You can convert your json string to a PHP array using $array = json_decode($str, true);, then loop your array and extract the information you need.
See http://php.net/manual/en/function.json-decode.php for more detail on json_decode
After json decode use this.
foreach($Item as $Items)
{
$ItemCategory = $Items->ItemCategory;
foreach($ItemCategory as $ItemCategorys)
{
echo $ItemCategorys->id;
}
}

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...

Add field to a JSON file

I have a very simple JSON file "json.txt" :
{
"status": true,
"data":
{
"clics":
[
{
"id": "1",
"title": "Title 1",
"comment": "Blablabla 1",
"url": "http://photostodisplay/1.jpg"
},
{
"id": "2",
"Title": "Title 2",
"comment": "Blablabla 2",
"url": "http://photostodisplay/2.jpg"
}
]
}
}
and I would like to add data and get the following result :
{
"status": true,
"data":
{
"clics":
[
{
"id": "1",
"title": "Title 1",
"comment": "Blablabla 1",
"url": "http://photostodisplay/1.jpg"
},
{
"id": "2",
"Title": "Title 2",
"comment": "Blablabla 2",
"url": "http://photostodisplay/2.jpg"
},
{
"id": "3",
"Title": "Title 3",
"comment": "Blablabla 3",
"url": "http://photostodisplay/3.jpg"
}
]
}
}
The php code I use return the following error :
Fatal error: Cannot use object of type stdClass as array in /home/XXXX/www/clic/test.php on line 10
Here is the php code
<?php
ini_set('display_errors',1);
ini_set('display_startup_errors',1);
error_reporting(-1);
$file = 'json.txt';
$data = json_decode(file_get_contents($file));
$newdata = array('id'=>'11', 'title' => 'sfdfsdfqf', 'comment' => 'sfdfwwfwdsdfqf', 'url' => 'sdfqwsfsdqqfqqqsfcq');
$data[] = $newdata;
file_put_contents($file, json_encode($data));
echo OK
?>
EDIT - Cezary answer gives almost what I need but is not. Here is what I get :
{
"status": true,
"data": {
"clics": [
{
"id": "1",
"title": "Title 1",
"comment": "Blablabla 1",
"url": "http://photostodisplay/1.jpg"
},
{
"id": "2",
"Title": "Title 2",
"comment": "Blablabla 2",
"url": "http://photostodisplay/2.jpg"
}
]
},
"0": {
"id": "11",
"title": "sfdfsdfqf",
"comment": "sfdfwwfwdsdfqf",
"url": "sdfqwsfsdqqfqqqsfcq"
}
}
The issue lies with this bit of code:
$data = json_decode(file_get_contents($file));
This returns an object, not an associative array. Change that line to this:
$data = json_decode(file_get_contents($file), true);
The second argument in json_decode specifies whether you want an associative array or not, and it defaults to false.
EDIT:
You're currently adding something to the root array. To add to the clics array, you can replace $data[] = $newdata; with:
$data['data']['clics'][] = $newdata;
Shouldn't that be
$data["data"]["clics"][]=$newdata;
or
array_push($data["data"]["clics"],$newdata);

PHP Troubles with converting from JSON to stdClass, making changes, and then converting back to JSON

So, in the very beginning, before the send_sms.php is loaded, I have this Json stored in a database:
{
"chats": {
"chat": [{
"id": "1",
"name": "Ethan Wilberforce",
"messages": {
"message": [{
"id": "1",
"name": "Ethan Wilberforce",
"text": "Hello how are you doing",
"time": "4:41"
}, {
"id": "2",
"name": "Qasim Iqbal",
"text": "Not bad. How about you?",
"time": "4:42"
}, {
"id": "3",
"name": "Ethan Wilberforce",
"text": "I'm not too bad myself.",
"time": "4:43"
}]
}
}, {
"id": "2",
"name": "Geoff Vahaaho",
"messages": {
"message": [{
"id": "1",
"name": "Geoff Vahaaho",
"text": "Hello how are you doing",
"time": "4:41"
}, {
"id": "2",
"name": "Qasim Iqbal",
"text": "Not bad. How about you?",
"time": "4:42"
}, {
"id": "3",
"name": "Geoff Vahaaho",
"text": "I'm not too bad myself.",
"time": "4:43"
}, {
"id": "4",
"name": "Qasim Iqbal",
"text": "Nice.",
"time": "4:43"
}]
}
}]
}
}
The Json is completely valid, no errors. It is storing two chats, with messages in them.
Now, here is the PHP code that alters the Json:
$data = $user->data;
$parsed_data = json_decode($data);
...
for($i = 0, $size = sizeof($parsed_data->chats->chat); $i < $size; ++$i) {
if($parsed_data->chats->chat[$i]->name == $to) {
$found = true;
$parsed_data->chats->chat[$i]->messages->message[sizeof($parsed_data->chats->chat[$i]->messages->message)] = new stdClass;
$parsed_data->chats->chat[$i]->messages->message[sizeof($parsed_data->chats->chat[$i]->messages->message)]->id = sizeof($parsed_data->chats->chat[$i]->messages->message);
$parsed_data->chats->chat[$i]->messages->message[sizeof($parsed_data->chats->chat[$i]->messages->message)]->name = $user->name;
$parsed_data->chats->chat[$i]->messages->message[sizeof($parsed_data->chats->chat[$i]->messages->message)]->text = $message;
$parsed_data->chats->chat[$i]->messages->message[sizeof($parsed_data->chats->chat[$i]->messages->message)]->time = $time;
echo "done. ";
break;
}
}
What I intend this to do is, to add another stdClass object in the "message" array of the chat. So I basically do just that, hoping it will work.
Now, it works, kind of, but here is the new Json after we json_encode it:
{
"chats": {
"chat": [{
"id": "1",
"name": "Ethan Wilberforce",
"messages": {
"message": [{
"id": "1",
"name": "Ethan Wilberforce",
"text": "Hello how are you doing",
"time": "4:41"
}, {
"id": "2",
"name": "Qasim Iqbal",
"text": "Not bad. How about you?",
"time": "4:42"
}, {
"id": "3",
"name": "Ethan Wilberforce",
"text": "I'm not too bad myself.",
"time": "4:43"
}, {}, {
"id": 4
}, {
"name": "Qasim Iqbal"
}, {
"text": "Hello i am testing"
}, {
"time": 1326066200
}]
}
}, {
"id": "2",
"name": "Geoff Vahaaho",
"messages": {
"message": [{
"id": "1",
"name": "Geoff Vahaaho",
"text": "Hello how are you doing",
"time": "4:41"
}, {
"id": "2",
"name": "Qasim Iqbal",
"text": "Not bad. How about you?",
"time": "4:42"
}, {
"id": "3",
"name": "Geoff Vahaaho",
"text": "I'm not too bad myself.",
"time": "4:43"
}, {
"id": "4",
"name": "Qasim Iqbal",
"text": "Nice.",
"time": "4:43"
}]
}
}]
}
}
You will notice it was indeed added in the "Ethan Wilberforce" chat, but each string in the stdClass was converted to its own array item in the "message" array. How could I fix this problem? Many thanks.
Your problem is this:
$parsed_data->chats->chat[$i]->messages->message[sizeof($parsed_data->chats->chat[$i]->messages->message)] = new stdClass;
$parsed_data->chats->chat[$i]->messages->message[sizeof($parsed_data->chats->chat[$i]->messages->message)]->id = sizeof($parsed_data->chats->chat[$i]->messages->message);
It basically amounts to:
$array[$last] = new stdClass();
$array[$last+1] = "id";
$array[$last+2] = "name";
You keep appending new arrays/objects, because you use sizeof(...) which always becomes one larger than the previous line. It's not the last index, but the size. Which is $lastindex+1.
What you should be doing anyway, is not using an object, but just appending an array, and with all its attributes at once:
$parsed_data->chats->chat[$i]->messages->message[] = array(
"id" => ...,
"name" => ...,
"time" => ...,
);
When you encode that associative array back into JSON it will also become a normal {...} JSON object group.
