PHP get JSON key value from specific object - php

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'];
}

JSON Post PHP (TypeForm)

I have never used JSON before so apologies if this is a simple request.
I have a webhook setup that sends me a JSON Post (Example Below) - I want to extract the two answers from this "text":"250252" & {"label":"CE"}
{
"event_id": "1",
"event_type": "form_response",
"form_response": {
"form_id": "VpWTMQ",
"token": "1",
"submitted_at": "2018-05-22T14:11:56Z",
"definition": {
"id": "VpWTMQ",
"title": "SS - Skill Change",
"fields": [
{
"id": "kUbaN0JdLDz8",
"title": "Please enter your ID",
"type": "short_text",
"ref": "9ac66945-899b-448d-859f-70562310ee5d",
"allow_multiple_selections": false,
"allow_other_choice": false
},
{
"id": "JQD4ksDpjlln",
"title": "Please select the skill required",
"type": "multiple_choice",
"ref": "a24e6b58-f388-4ea9-9853-75f69e5ca337",
"allow_multiple_selections": false,
"allow_other_choice": false
}
]
},
"answers": [
{
"type": "text",
"text": "250252",
"field": {
"id": "kUbaN0JdLDz8",
"type": "short_text"
}
},
{
"type": "choice",
"choice": {
"label": "CE"
},
"field": {
"id": "JQD4ksDpjlln",
"type": "multiple_choice"
}
}
]
}
}
I have this currently in my PHP file:
$data = json_decode(file_get_contents('php://input'));
$ID = $data->{"text"};
$Skill = $data->{"label"};
This does not work and all I get is null - Any help would really be appreciated, Thank You.
You need to look at the JSON object you're receiving to know the structure of the object you're receiving after using json_decode, what you're trying to get is in $data->form_response->answers, So you can have a variable for easier access:
$answers = $data->form_response->answers;
remember $answers is an array
So to achieve what you're trying to get, you can do:
$data = json_decode(file_get_contents('php://input'));
$answers = $data->form_response->answers;
$ID = $answers[0]->text;
$Skill = $answers[1]->choice->label;

Get data from JSON file with PHP (empty result with numbers)

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'];

Accessing array inside array

I'm working on my task right now, which accessing specific array when it is called by front end.
My example data is like this
{
"data": [
{
"name": "Jon Snow",
"id": "01-0001",
},
{
"name": "Robert Stark",
"id": "01-0002"
},
{
"name": "Sansa Stark",
"id": "01-002333"
},
{
"name": "Arya Stark",
"id": "01-00012"
},
{
"name": "Bran Stark",
"id": "01-0003"
},
{
"name": "Rickon Stark",
"id": "01-0005"
}
]
}
* In my front end I have this code *
selectedEmployee: any=null;
setActiveEmployee(employee: any) {
this.selectedEmployee = employee;
let myJSON = JSON.stringify(this.selectedEmployee);
this.perEmpLateEarly();
}
Whenever I choose the employee i get the id of that employee.
So in this, if i choose "id": "01-0001" it will return the first array and it will keep the rest, and if I choose "id": "01-0002" it will return the second one and will keep the rest and so on. How can I do that in Php?
Thanks in advance
You will do a GET/POST HTTP request from frontend, which would look something like this in
your_backend_page.php?id=<ID HERE>
Then the "your_backend_page.php" would look like as follows:
$list = { "data": [ { .... }, { ... }] } // this is the array you have
$idFromFrontEnd = $_GET["id"];
foreach ($list["data"] as $item) { // iterate over all items
if ($item["id"] == $idFromFrontEnd) { // check if id matches
echo json_decode($item); // if matches, print this item
}
}
Please note this approach is okay if you have a small number of items. For a larger list, you might want to have a database, where you can use sql to select.

Foreach empty from json

I have the following url:
https://graph.facebook.com/123456/likes?access_token=__ACCESS_TOKEN__&format=json
which I then do:
$likesList = json_decode(file_get_contents("https://graph.facebook.com/123456/likes?access_token=$access_token&format=json"),true);
which produces e.g.
{
"data": [
{
"name": "yo yo yo",
"category": "Entertainer",
"id": "45640987076",
"created_time": "2012-04-18T16:14:09+0000"
},
{
"name": "Tony Smith",
"category": "Musician/band",
"id": "456456456456",
"created_time": "2012-02-22T06:56:18+0000"
},
{
"name": "Stations",
"category": "Company",
"id": "567657567",
"created_time": "2012-01-30T23:08:39+0000"
}
]
}
and I then want to list e.g. all the names returned so:
foreach ($likesList->data as $element2){
$name = $element2[name];
echo $name;
}
But it's empty?
See this visualization of your data structure.
As you are receiving an array, you need $list["data"] and not $list->data. Also don't forget to quote the array key "name".
foreach ($likesList['data'] as $element2){
$name = $element2['name'];
echo $name;
}
After json_decode with parameter true you will have associative array. You can access to value by string key. Like in example above.

imploding array_keys from Facebook JSON data

Need some help with the sample code provided the facebook. I can't get it to return a series of IDs that I need to run a sql query against.
$friends = '{
"data": [
{
"name": "Paul",
"id": "12000"
},
{
"name": "Bonnie",
"id": "120310"
},
{
"name": "Melissa",
"id": "120944"
},
{
"name": "Simon",
"id": "125930"
},
{
"name": "Anthony",
"id": "120605"
},
{
"name": "David",
"id": "120733"
}
]
}';
$obj = json_decode($friends);
print $obj->{'data'}[0]->{'name'};
I can return the "Paul"
what I want is to return all the id's using implode(array_keys($obj),",")
I am only getting data to return.
What I'd like to do is retrieve all the IDs separated by a comma.
Thanks!
Try implode-ing on the data key with array_map:
function get_id($o) {
return $o->id;
}
implode(array_map('get_id', $obj->data),",")
