I have this JSON in a request for an laravel API:
{
"questionary": {
"directLeader": {
"answer": "ALWAYS",
"comments": "asdf"
}
},
"id": 14
}
I need to obtain the string "directLeader" 'cause this key changes in the request and I used that as a reference for a query update.
To convert json to array:
$array = json_decode($json, true);
To get the first key inside associative array:
$firstKey = array_key_first($array['questionary']);
$firstKey will contain your dynamic key.
You need to json_decode() the json you have like so
$json = '{
"questionary": {
"directLeader": {
"answer": "ALWAYS",
"comments": "asdf"
}
},
"id": 14
}';
$encoded_json = json_decode($json, true);
dd($encoded_json['questionary']['directLeader']);
Note
the true in json_decode() will convert the object to array, without true it will an object

I'm trying to get data from the following JSON file using PHP
I Want To Get All URls (link) ,
http://www.google.com
http://www.bing.com
Json
Here is what I tried
PHP
Thanks
You cannot access an object property using a number, it must be a string.
It is much easier to output json_decode as an array, and access properties that way. To do this, put true as the second parameter.
<?php
$json = '
{
"news": {
"name": "yahoo",
"url": "https://yahoo.com"
},
"links": [
{
"id": "1",
"url": "https://google.com"
},
{
"id": "2",
"url": "https://bing.com"
}
]
}';
$decode = json_decode($json, true);
echo $decode['links'][0]['url'];
I have made a http request to my api using Guzzle library as follow :
$client = new Client();
$response = $client->request(
'GET',
config('some_url');
$serverResponse = json_decode($response->getBody(),true);
if ($serverResponse['result']) {
$data = $serverResponse['data'];
Now I got the response as
{
"result": true,
"data": {
"101": {
"id": 101,
"name": "ABCD",
"age" : 24
},
"102": {
"id": 102,
"name": "EFGH",
"age" : 24
},
"103": {
"id": 103,
"name": "IJKL",
"age" : 24
},
}
}
The problem is I need to read and push the object models 101,102,103 to a separate array. for this I try to get the objects as following options. but I could not able to get the results rather than errors.
$obj = $data[0];
It returns Undefined offset: 0 error
Because your data is being manually indexed, as opposed to something like:
{
"data": {
0: {
"id": 101,
...
},
1: {
"id": 102,
...
},
...
}
}
You will need to specify these indexes when fetching the data. E.g:
$data["101"]
To do this for dynamically set data you can use array_keys
$obj = $data[array_keys($data)[0]];
Using array_keys allows you to search $data by the numerical index of $data
If you simply want to re-index the array so that the keys are [0], [1], [2], etc. you can use the following:
$newArray = array_values($data);
You will then be able to access the first sub-array with $newArray[0], the second with $newArray[1], etc.
You can convert the response to object and then you can access the properties as following.
$obj = json_decode($response->getBody());
$one_zero_one = $obj->data->{101};
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
}
can someone please help me to add data to following json.
$temp='{
"custId": 123,
"data": [
{
"code": "abc1"
},
{
"code": "abc2"
}
],
"id": 102
}';
data to be added
$data1='{
"code": "abc3"
}';
Desired result
$temp='{
"custId": 123,
"data": [
{
"code": "abc1"
},
{
"code": "abc2"
},
{
"code": "abc3"
}
],
"id": 10
}';
I can append data to $temp, but can someone please help to add data to specific position with php. Thank you in advance. (I've tried json_decode($temp, true) and then finding the location where data1 is to be added but failed).
You can convert your data to a normal PHP array:
$array = json_decode($temp, true);
then just add or change anything you want:
$array["data"][] = array(["code"] => "abc3");
and re-encode to json:
$temp = json_encode($array);// encode to json
http://php.net/manual/en/function.json-decode.php
first, you need to convert the JSON into PHP array like this:
$array = json_decode($temp, true);
Then, it's as simple as:
$array['data']['code'] = 'abc3';
If the string that you want to add is still a JSON, you have to convert that one in an array as well so:
$arr_to_add = json_decode($data1, true);
$array['data'][] = $arr_to_add;
In the end, of course, encode again like this:
$final_json = json_encode($array);
Hope this helps! :D
First you need to decode the json with json_decode. This returns a PHP variable.
Add desired values.
Use json_encode to get the json with new values. Returns a string containing the JSON.
you can try this:
<?php
$temp='{
"custId": 123,
"data": [
{
"code": "abc1"
},
{
"code": "abc2"
}
],
"id": 102
}';
$data1='{
"code": "abc3"
}';
$jarr=json_decode($temp,true);
$appArr=json_decode($data1,true);
$desire=array_merge($jarr,$appArr);
//print_r($desire);
echo json_encode($desire);
I have a json string similar to
{
{
"field": value,
"other_field": value,
"object field": {
"field": stuff
}
},
{
"field": value,
"other_field": value,
"object field": {
"field": stuff
}
}
}
and I need to convert it into an array of json strings, so each element of the output array is similar to
{
"field": value,
"other_field": value,
"object field": {
"field": stuff
}
}
I know there's json_decode(), but that will turn the entire thing into a bunch of nested arrays, but I only want to do that to the top level. Is there an easy way to do this, or am I better off decoding the whole string and re-encoding each element?
You have to decode the json string, then encode each array element:
$arr = json_decode($json);
$res = array();
foreach ($arr as $entry) {
$res[] = json_encode($entry);
}
json_decode( $json )[0] to get the first array element. Does this satisfy what you're looking for?
I think you'll have to rethink what you're doing because it's fishy. Here's one solution to what you're asking though:
<?php
$json = '[ {"foo": 1, "bar": true}, {"foo": 2, "bar": false} ]';
array_map('json_encode', json_decode($json));
// Array
// (
// [0] => {"foo":1,"bar":true}
// [1] => {"foo":2,"bar":false}
// )
