I have data i want to get from array without loop.
I want to get "value" of "link_click" for example, how can i make this work?
I tried: but this not working.
$stats = json_decode($data, false);
$link_click= $stats->data->actions->action_type->['link_click']->value;
{
"data": [
{
"actions": [
{
"action_type": "comment",
"value": 2
},
{
"action_type": "link_click",
"value": 636
},
{
"action_type": "post_like",
"value": 2
},
{
"action_type": "page_engagement",
"value": 640
},
{
"action_type": "post_engagement",
"value": 640
}
],
The only way you can make it possible only if you know the index of the action_type:link_click. If you know the index, you can do it by. (Answer is with respect to the data you have shown above).
$stats = json_decode($data, true);
$link_click= $stats['data']['actions'][1]['value'];
Loop example (on request):
$stats = json_decode($data, true);
$value = 0;
foreach($stats['data']['actions'] as $action) {
if ($action->action_type == 'link_click') {
$value = $action->value;
}
}
echo $value; //This is your value
You can use something like JsonPath to get the value

Ive got the following JSON:
{
"servers": [
{
"id": "f34c0185-4c9e-40fd-82f6-1d6e9a5d499e",
"name": "vm01"
},
{
"id": "d671ac7d-3b5a-4777-8510-6e8e58295061",
"name": "vm02"
},
{
"id": "h59j23cc-9ve2-4508-1277-85y1lo27562m",
"name": "vm03"
}
]
}
I also have another JSON that gives me the ID I want to search for.
For example: "d671ac7d-3b5a-4777-8510-6e8e58295061".
I want to search for the JSON Object, that contains that ID and get the value of the name key. I tried with loops and if, else's but I didn't manage to get it working.
Thanks for your help!
decode the json as array object then loop through with the ID that u want to search
<?php
$json = '{
"servers": [
{
"id": "f34c0185-4c9e-40fd-82f6-1d6e9a5d499e",
"name": "vm01"
},
{
"id": "d671ac7d-3b5a-4777-8510-6e8e58295061",
"name": "vm02"
},
{
"id": "h59j23cc-9ve2-4508-1277-85y1lo27562m",
"name": "vm03"
}
]
}';
$j = json_decode($json, true);
foreach($j['servers'] as $arr)
{
if( $arr['id'] == 'd671ac7d-3b5a-4777-8510-6e8e58295061' ) echo $arr['name'];
}

I am working on a project that requires reading data from this terrible API that responds with terrible structured JSON data:
"finn-contanct": {...}
"finn-adata": {
"#attributes": {
"model": "https://cache.api.finn.no/iad/ad/model/car-used-sale"
},
"finn-field": [
{
"#attributes": {
"name": "authorized_dealership",
"value": "true"
}
},
{
"#attributes": {
"name": "body_type",
"value": "Stasjonsvogn"
}
},
{
"#attributes": {
"name": "car_location",
"value": "Norge"
}
},
{
"#attributes": {
"name": "engine"
},
"finn-field": [
{
"#attributes": {
"name": "effect",
"value": "90"
}
},
{
"#attributes": {
"name": "fuel",
"value": "Diesel"
}
}
]
},
{...},
]
}
How can i dynamically get the values under each attribute based on the siblings name value? Ideally with a function that accepts one parameter that finds the value in there by providing a key corresponding to the value i'm looking for.
Here is an example of what i'm expecting:
Given a function that expects one parameter: getAttrValue('key') I want to get the value under the #attributes sibling. So if I use the function like this: getAttrValue('body_type') i'm simply expecting this back: Stasjonsvogn. I don't really care about nested items. So if I do this: getAttrValue('fuel') I'm simply expecting: Diesel
I found this answer here on SO. But the problem with that method is that it doesn't work well with nested items. So does anyone have a method that would work with the data-structure I got above here?
The response is a total mess and I don't know how to handle it, nor how to Google it properly. So any help would be appreciated greatly.
Collect attributes into associative array recursively:
function collectAttributes($data)
{
$attributes = [];
$nodeAttribute = isset($data['#attributes']) ? $data['#attributes'] : [];
//collect current node attribute value
if (isset($nodeAttribute['name'])) {
$attributes[$nodeAttribute['name']] = isset($nodeAttribute['value']) ? $nodeAttribute['value'] : '';
}
//collect nested attributes recursively
foreach ($data as $nestedNode) {
if (is_array($nestedNode)) {
$attributes = array_merge($attributes, collectAttributes($nestedNode));
}
}
return $attributes;
}
And then use result as simple associative array:
$data = json_decode($inputJson, true);
$atttributes = collectAttributes($data);
echo $attributes['fuel']; //don't forget isset checking if you are not sure about content
But if you have attributes with same name you'll see only latest this way.
My json file look likes
myjson.json
[
{"name":"category_01","data":
[
{"id":"1","word":"ma","given_value":"1"},
{"id":"3","word":"me","given_value":"1"},
] }
[
{"name":"category_02","data":
[
{"id":"1","word":"vea","given_value":"1"},
{"id":"3","word":"ve","given_value":"1"},
] }
So what I want here is, check whether a particular value is in this json array using php. Assume that,
myphp.php
$word = 've';
if this value is in the above array, should find is it in category_01 or category_02. and also want to find given_value of matching word.
I just tried in this way,
$data = file_get_contents ("myjson.json");
$json = json_decode($data, true);
foreach($arr as $item) {
$uses = ($item['word']= $word);
}
This doesn't work. How can I fix this, Please help me!
First of all, the JSON you posted is invalid. I think it should look like this:
[
{
"name": "category_01",
"data": [{
"id": "1",
"word": "ma",
"given_value": "1"
},
{
"id": "3",
"word": "me",
"given_value": "1"
}
]
},
{
"name": "category_02",
"data": [{
"id": "1",
"word": "vea",
"given_value": "1"
},
{
"id": "3",
"word": "ve",
"given_value": "1"
}
]
}
]
Try using on online tool like https://jsonlint.com/ to check your JSON. (if you get errors i recommend build the json again from scratch).
I also recommend checking your json before using it:
if ($arr === null && json_last_error() !== JSON_ERROR_NONE) {
die("incorrect json data");
}
To get your value you have to KNOW how your data looks like and then process it:
foreach($arr as $category) {
foreach($category['data'] as $data) {
if(strstr($data['word'], $word))
echo $category['name'].' '.$data['word'].' '.$data['given_value']."\n";
}
}
i have simple json results like below
{
"code": 200,
"image": "https://example.com/image.jpg",
"result": [
{
"url": "https://example.com/1",
"label": "MP4"
},
{
"url": "https://example.com/2",
"label": "FLV"
},
{
"url": "https://example.com/3",
"label": "MP3"
},
{
"url": "https://example.com/4",
"label": "AVI"
},
{
"url": "https://example.com/5",
"label": "WMV"
}
]
}
as you can see, that there are so many different label paths, and sometimes the sequence of labels is not like the above, it's always changing (random), and I'm trying to get the MP3 label part but can not.
My question is, how to take the sequence of json which has MP3 label?
I have tried with the script below
$uri = json_decode(file_get_contents('https://example.com/json.json'),TRUE);
echo $uri['result'][2]['url'];
but as described above, the position of the MP3 label is always changing, is there a way to overcome it?
Try following code:
$nodesWithMp3Labels = array_map(function($a) {
if (strtolower($a["label"]) == "mp3") {
return $a;
}
}, $uri['result']);
Read more about array_map
With array_map, there will be some blank values if label is not mp3.
Another solution using simple foreach loop:
$nodesWithMp3Labels = [];
foreach ($uri['result'] as $a) {
if (strtolower($a["label"]) == "mp3") {
$nodesWithMp3Labels[] = $a;
}
}
You should use array_filter to get all the results with MP3 label:
$uri = json_decode(file_get_contents('https://example.com/json.json'), true);
$mp3 = array_filter($uri['result'], function($item) {
return $item['label'] === 'MP3';
})
I have the following deocoded JSON array.
I need to access the "type" inside the context, as well as I need to loop through each of the values in the payload. How do I do that?
{
"RequestHeader":
{
"mess": "am putting it on my wall....",
"created_time": "2010-08-24T09:01:25+0000"
},
"context" :
{
"type": "friends,circles"
}
"payload" [ {12345},{12345} ,{2345} ]
}
I tried the following, but it doesn't work
$decoded = json_decode($json_string);
for ($i=0;$i<payload.length;++$i)
{
$id=$decoded->payload[$i];
//do some operation with the id
}
First of all the JSON you provided is invalid. Supposedly the valid one should look like this
{
"RequestHeader": {
"mess": "am putting it on my wall....",
"created_time": "2010-08-24T09:01:25+0000"
},
"context": {
"type": "friends,circles"
},
"payload": [
12345,
12345,
2345
]
}
After you've fixed the problem with JSON provider it will be quite easy to access data
<?php
$json = <<<'JSON'
{
"RequestHeader": {
"mess": "am putting it on my wall....",
"created_time": "2010-08-24T09:01:25+0000"
},
"context": {
"type": "friends,circles"
},
"payload": [
12345,
12345,
2345
]
}
JSON;
$data = json_decode($json, true);
$type = $data['context']['type'];
var_dump($type);
foreach($data['payload'] as $id) {
var_dump($id);
}
Remember to make sure you check that the data actually exists before accessing it, e.g. isset($data['context']['type']) unless you are absolutely sure in it's integrity.
When you use json_decode method, the output will be nested arrays
So for example to access context type you need to do the following
echo $decoded["context"]["type"];
And to loop on payload you need to do the following
for ($i=0;$i<$decoded["payload"].length;++$i)
{
$id=$decoded["payload"][$i];
//do some operation with the id
}
