I want to parse values from an Json API, but I cant get it to work
The API returns this JSON:
[
{
"assets": [
{
"id": 6,
"size": 1429504,
"download_count": 1,
"browser_download_url": "https://dl.domain.tld/files/cdbc6e19-cd86-4ed6-8897-37ec5aaee578"
}
]
}
]
I tried to get the ID value like this:
$json_obj = json_decode($resp);
print $json_obj->assets[0]->id;
but I get no result whereas it should be 6. What do I do wrong here?
Remember the outer part of the JSON is an array, as suggested by the opening [. So you need to first access the first (and only) element of it:
$json_obj[0]->assets[0]->id; //<-- note the first [0]
I think the correct answer is
$json_obj = json_decode($resp);
print $json_obj[0]->assets[0]->id;
The json object will be converted to a php array, since you have an array with a object inside in your case it will be a multidimentional array with the objects inside.
Try this its worked for me..
$json ='[
{
"assets": [
{
"id": 6,
"size": 1429504,
"download_count": 1,
"browser_download_url": "https://dl.domain.tld/files/cdbc6e19-cd86-4ed6-8897-37ec5aaee578"
}
]
}
]';
$json_obj = json_decode($json);
var_dump($json_obj[0]->assets[0]->id)
?>
decode JSON to the array and fetch the id by proper array keys
$jToArray = json_decode($resp, TRUE);
echo $jToArray[0]['assets'][0]['id'];//You will get the correct id

i'm trying to get the fields "name, price, image and rarity" to show in a php file, anyone can help me? Thanks ;D
{
"status": 300,
"data": {
"date": "2019-09-16T00:00:00.000Z",
"featured": [
{
"name": "Flying Saucer",
"price": "1,200",
"images": {
"icon": icon.png",
},
"rarity": "epic",
},
I'm using this that a friend told me, but i cant put that to work :c
<?php
$response = json_decode(file_get_contents('lista.json'), true);
foreach ($response as $val) {
$item = $val['name'];
echo "<b>$item</b>";
}
?>
I'm not quite sure what you are trying to achieve. You can just access the contents via the $response array like this:
echo $response['status']; // would output 300
You can use foreach to iterate through the array. For example: If you want to output the name of every element of the array you can use:
foreach ($response['data'] as $val) { // loop through every element of the data-array (if this makes sense depends on the structure of the json file, cant tell because it's not complete)
echo $val['featured']['name'];
}
You gotta get the index in $val['data']['featured']['name'] to retrieve the name index.
When you defined the second parameter of json_decode, you said that you want your json to be parsed to an array. The brackets in the original json identify when a new index of your parsed array will begin.
I suggest you to read about json_decode and json in general:
JSON: https://www.json.org/
json_decode function: https://www.php.net/manual/en/function.json-decode.php
I feel like i am slightly insane, and I have certainly read the docs on this. I am completely unable to echo out various objects in a JSON array in PHP. I am not sure what I'm doing wrong, but I'm ripping my hair out...
Here is my JSON array:
{
"photos": {
"page": 1,
"pages": 1569045,
"perpage": 1,
"total": "1569045",
"photo": [
{
"id": "14842817422",
"owner": "23432140#N06",
"secret": "c37cfa1914",
"server": "3864",
"farm": 4,
"title": "pizza",
"ispublic": 1,
"isfriend": 0,
"isfamily": 0
}
]
},
"stat": "ok"
}
I know this is simple, but I can't get it right. I would like to echo out four different values.
This is what I have been trying:
$photoId = $jsonDecoded['photos']['photo'][0]['id'];
$photoSecret = $jsonDecoded['photos']['photo'][0]['secret'];
$photoServer = $jsonDecoded['photos']['photo'][0]['server'];
$photoFarm = $jsonDecoded['photos']['photo'][0]['farm'];
I know this seems newbie. Please help...
Best,
The problem is that you have both objects and arrays in your json, but are using array syntax in your php.
There are two ways to fix this, 1st simply set the second parameter of json_decode to true:
json_decode($json, true);
This will create a multidimentional array you can access as suggested in your question, eg:
$photoId = $jsonDecoded['photos']['photo'][0]['id'];
Alertinitivly you can use object property syntax on your existing $jsonDecoded:
$photoId = $jsonDecoded->photos->photo[0]->id;
if there are multiple photo sub arrays then you can do like this.
//this will create array instead of object
$jsonDecoded = json_decode($your_feed_data,true);
foreach($jsonDecoded['photos']['photo'] as $sub_array){
$photoId = $sub_array['id'];
$photoSecret = $sub_array['secret'];
$photoServer = $sub_array['server'];
$photoFarm = $sub_array['farm'];
}
please help me how to parse following JSON in PHP.
I got following JSON using PIWIK reporting api. How do I get PageTitle from following json in PHP. I tried following code for JSON parsing.
$json = '[
{
"idSite": "1",
"idVisit": "84",
"visitorId": "f08dc1f2a3e1f839",
"visitorType": "returning",
"visitorTypeIcon": "plugins/Live/images/returningVisitor.gif",
"visitConverted": "0",
"visitConvertedIcon": null,
"visitEcommerceStatus": "none",
"visitEcommerceStatusIcon": null,
"searches": "0",
"events": "4",
"actions": "9",
"actionDetails": [
{
"type": "action",
"url": "http://mywwebsiteurl.com",
"pageTitle": "PageTitle",
"pageIdAction": "110"
}
]
}
]';
$visits = json_decode($json, true);
foreach ($visits->actionDetails as $data) {
echo $data->pageTitle;
}
I got following notice
Notice: Trying to get property of non-object
How to get pageTitle from above JSON.
It should be :-
$visits = json_decode($json, true);
foreach ($visits[0]["actionDetails"] as $data) {
echo $data["pageTitle"];
}
You set second attribute to TRUE - so according to the manual.
"When TRUE, returned objects will be converted into associative arrays."
Try using the array aproach
foreach ($visits['actionDetails'] as $data){
echo $data['pageTitle'];
}
As documented in the manual, and mentioned by Matt, the second parameter of json_decode() controls the return type. If it is omitted or set to false (the default) then an object is returned. If it is set to true an array is returned.
Your code, json_decode($json, true);, will return an array but you then try to use the array as an object.
I wonder how to parse a json array without values
Json: {"status":"FAILED","errors":{"email":["NOT_UNIQUE"],"name":["TOO_SHORT"]}}
How can i get the value of email in a foreach loop?
What i mean with "without value" is: there is an array called email and name... How can i get the value for "email" that currently says NOT_UNIQUE?
In your current example, your JSON string is malformed. I dont know if thats a typo on your part while creating your question. Assuming the JSON string is okay in your code, a simple json_decode() will do just fine. Consider this example:
$json_string = '{ "Json": { "status": "FAILED", "errors": { "email": [ "NOT_UNIQUE" ], "name": [ "TOO_SHORT" ] } }}';
$data = json_decode($json_string, true);
echo $data['Json']['errors']['email'][0]; // NOT UNIQUE
use json_decode, json_decode($str, true) will return it as an assosiative array whereas json_decode($str, false) will return objects.
json_decode("{"status":"FAILED","errors":{"email":["NOT_UNIQUE"],"name":["TOO_SHORT"]}}", true)['errors']['email']
should get the email for you.
I'm trying to get into just data from
{
"data": [{
"media_count": 3045,
"name": "snow",
},
{
"media_count": 79,
"name": "snowman",
},
{
"media_count": 40,
"name": "snowday",
},
{
"media_count": 29,
"name": "snowy",
}]
}
I've been trying, using:
$obj = json_decode($res[0], true);
echo $obj['data']; //this returns an array
I also tried this:
$obj = json_encode($res[0], true);
echo $obj; // this returns json, but not inside `data`
"data": [{
"media_count":54373,
"name":"test"
}]
I just want to get inside data. How would I do so?
Thanks in advance!
UPDATE: Sorry to mention, I would like this in json format please
eventually, I would like to only see
{
"media_count":54373,
"name":"test"
}
Something like thiat
Use json_encode() to get what you want:
$obj = json_decode($res[0], true);
echo json_encode($obj['data']);
In your first example, $obj['data'] returns an array because that's how the JSON is set up. According to the JSON, data is a collection of elements.
To access within the array, you can do this:
foreach($obj['data'] as $object) {
print_r($object);
}
You can also index into it as you want:
print_r($obj['data'][0]);
EDIT
If I'm getting you correct, you want to convert the first JSON to this:
"data": [{
"media_count":54373,
"name":"test"
}]
If so, that is not possible since the second fragment is not valid JSON. (use http://jsonlint.com)
firstly access the data item of the json array;
$obj1=$obj[item];
$sizeobj=sizeof($obj1);
for($i=0;$i<$sizeobj;$i++)
{
// your code to access the data items
// for eg $obj[item][$i][media_count}
}
