json decode - getting single array from object? - php

I have a json file which I decode using json_decode. The json file is an object which holds two arrays. I only want the first array but I'm having trouble figuring out how.
Json file
{
"app":{
"available":{
"stats":[
{
"name":"the name",
"at":"url"
},
{
"name":"the name",
"at":"url"
}
],
"stats2":[
{
"name":"the name",
"at":"url"
},
{
"name":"the name",
"at":"url"
}
]
}
}
}
I use
foreach($data3['app']['available'] as $name => $value)
{
foreach($value as $entry)
{
echo $entry['name'];
}
}
The output I get every name from both stats1 and stats2 arrays. I only want the names from stats1 array, not stats2. How can this be achieved?

because there are two arrays in app->available: stats and stats2
If you are interested in only stats, why don't you try:
foreach($data3['app']['available']['stats'] as $name => $value)
__UPDATE__
Try this one please
$in = '{"app":{"available":{"stats": [{"name":"the name","at":"url"},{"name":"the name", "at":"url"}],"stats2":[{"name":"the name","at":"url"},{"name":"the name","at":"url"}]}}}';
$obj = (array) json_decode($in, true);
foreach($obj['app']['available']['stats'] as $value)
{
foreach($value as $e => $v)
{
echo ($value['name'] );
echo ("\r");
}
}

JSON Get the name of dynamically changing key with PHP

I am having trouble getting the name of a dynamic key from a JSON string.
I am using PHP
This is a sample of the JSON
{
"_text": "this is a test",
"entities": {
"dynamic_key": [
{
"confidence": 0.99,
"value": "thi is the answer"
}
]
},
"msg_id": "1234532123"
}
I am using foreach to go trough the json key and get the values
foreach ($json as $obj) {
$search_term = $obj->_text;
$msg_id = $obj->msg_id;
}
But I am not sure how to get the value of the "dynamic_key" which changes every time, and because of that I also cannot get the values of "confidence and value" keys.
Any ideas on how to approach this?
Followed #Dimi, solution. This is what I ended up with
$data=json_decode($json,true);
foreach ($data['entities'] as $key=>$val)
{
echo "Entity: $key";
foreach ($data['entities'] as $keys){
$conf = $keys[0]['confidence'];
$answer = $keys[0]['value'];
echo "conf: $conf, answ: $answer";
}
}
Can you provide a couple more examples?
Or try this code and let us know if it breaks
<?php
$json='{
"_text": "this is a test",
"entities": {
"dynamic_key": [
{
"confidence": 0.99,
"value": "thi is the answer"
}
]
},
"msg_id": "1234532123"
}';
$data=json_decode($json,true);
foreach ($data['entities'] as $key=>$val)
{
echo "VALUE IS $key\n values are ";
var_dump($val);
}
Using the data you've shown, there doesn't seem to be an array for the starting JSON.
But with that data the following will use foreach to both fetch the key and the data and then another sub-loop to fetch the confidencevalue...
$search_term = $json->_text;
$msg_id = $json->msg_id;
foreach ( $json->entities as $key => $entities ) {
echo $key.PHP_EOL;
foreach ( $entities as $entity) {
echo $entity->confidence.PHP_EOL;
}
}
If you decode the JSON as an array and if the dynamic key is the only key under entities, then:
$array = json_decode($json, true);
$dynamic = current($array['entities']);
$confidence = $dynamic['confidence'];
$value = $dynamic['value'];
Or shorter:
$confidence = current($array['entities'])['confidence'];
You can probably use reset, current and maybe array_pop etc.

Getting values from a JSON that has separated string as keys

I have a JSON that I would want to get the values from. However, the key values are typical key. They are not one worded.
[
{
"quality-of-service": "Good"
},
{
"quality-of-staff": "Great"
},
{
"quality-of-communication": "Excellent"
},
{
"value-for-money": "Excellent"
}
]
How do I get the values for the keys.
After decoding $array = json_decode($json, true), the first value would be $array[0]['quality-of-service'] which is not a good way to do it. You could loop:
foreach($array as $values) {
echo key($values) . " is " . current($values);
}
Or you can flatten the array:
$array = array_merge(...$array);
Then use $array['quality-of-service'] or loop it:
foreach($array as $key => $value) {
echo "$key is $value";
}

Adding key in an Array PHP

Im studying in array, and I was wondering How can I add key to this kind of array?
{
"items":[
{
"count":"1",
"id":123,
"description":"Bag",
"price":11
},
{
"count":1,
"id":1234,
"description":"10% Discount",
"price":-1.1
}
],
"total":9.9,
"discount_total":9.9
}
because I needed convert the array to have a key base on the id inside the array.
{
"items":{
"123":{
"count":"1",
"cart_id":123,
"description":"Bag",
"price":11
},
"1234":{
"count":1,
"cart_id":1234,
"description":"10% Discount",
"price":-1.1
}
},
"total":9.9,
"discount_total":9.9
}
and this is my code
header('Content-Type: application/json');
$cart_array = json_decode('{
"items":[
{
"count":"1",
"cart_id":123,
"plu":"TP16",
"description":"Bag"
},
{
"count":1,
"cart_id":1234,
"plu":"DISCT10",
"description":"10% Discount"
}
],
"total":9.9,
"discount_total":9.9
}');
foreach ($cart_array->items as $item)
{
$construct["cart_id"] = $item->cart_id;
}
I wanted to ask how can I put the id in the array? I cant use $cart_array['id'] = $value, it returns error.
Uncaught Error: Cannot use object of type stdClass as array
I could really use some explanation here
Following code can help you.
<?php
$json = '{
"items":[
{
"count":"1",
"cart_id":123,
"plu":"TP16",
"description":"Small Four Seasons"
},
{
"count":1,
"cart_id":1234,
"plu":"DISCT10",
"description":"10% Discount"
}
],
"total":9.9,
"discount_total":9.9
}';
$data = json_decode($json,TRUE); //json decode
foreach ($data['items'] as $key => $value)
{
$data['items'][$value['cart_id']] = $value;
unset($data['items'][$key]);
}
echo "<pre>";print_r($data);die;
?>
You don't have to loop at all. You can use array_column to make an array associative with one line of code.
$cart_array['items'] = array_column($cart_array['items'], NULL, 'cart_id');
https://3v4l.org/cPD5n
You can use this code in your application to add keys to indexed array.
foreach($obj as $key=>$val){
foreach ($val as $index=>$content){
$data[$content['id']]=$content;
}
}
You can get same output json data as per you want :
$array = json_decode($data,true);
if(isset($array['items']) && count($array['items']) > 0){
foreach($array['items'] as $key => $value){
$value['cart_id'] = $value['id'];
unset($value['id']);
$array['items'][$value['cart_id']] = $value;
unset($array['items'][$key]);
}
}
echo "<pre>";print_r($array);
echo json_encode($array);

How to iterate JSON using PHP?

Can any one tell me how to iterate below given JSON data using PHP,
{
"value1":"3",
"value 2":"5",
"Id":[
"210",
"211"
]
}
<?php $json='{ "value1":"3", "value 2":"5", "Id":[ "210", "211" ] }';
$getarr=json_decode($json,true);
foreach( $getarr as $key => $value)
{
if(is_array($value))
{
// ID has an array so retrieve a value
foreach($value as $key1 => $value1)
{
echo $key."=>".$value1;
}
}else
{
echo $key."=>".$value;
}
} ?>
It will be produce the below output. Hope it will be helpful to solve your problem
Answer:
value1=>3 value 2=>5 Id=>210 Id=>211
Use json_decode function for converting it to array.
$array = json_decode( $json, true );
Copy and paste you can change the print out to fit your use
<?php
$bar=' { "value1":"3", "value 2":"5", "Id":[ "210", "211" ] }';
//var_dump($bar);
$JSONdata = json_decode($bar, true);
//echo
$JSONdataValue="";
$JSONdataValue.=$JSONdata['value1']."<br>";
$JSONdataValue.=$JSONdata['value 2']."<br>";
$JSONdataValue.=$JSONdata['Id'][0]."<br>";
$JSONdataValue.=$JSONdata['Id'][1]."<br>";
echo $JSONdataValue;
?>

json parsing with php foreach

I was trying to parsing json file below from a link but I still can't figure it out about parsing and display it with foreach.
data: [
{
id: "1072",
nik: "013977",
status: "",
name: "RAKHMAT KUSNADI",
birthdate: "1983-10-21",
email: "rakhmat.koes#gmail.com",
first_login: "0",
is_juri: "0",
what_juri: "",
categorized: "0",
back_stage: "0",
placement: [
{
rel_id: "1102",
employee_id: "1072",
department_id: "101",
dept: "Chip",
position_id: "1",
position: ""
}
],
profile_pics: "link"
},
{
id: "1069",
nik: "013377",
status: "",
name: "RENATA MARINGKA",
birthdate: "1987-05-20",
email: "",
first_login: "1",
is_juri: "0",
what_juri: "",
categorized: "0",
back_stage: "0",
placement: [
{
rel_id: "1099",
employee_id: "1069",
department_id: "101",
dept: "Chip",
position_id: "1",
position: ""
}
],
profile_pics: "link"
},
]
}
I want to display name and profile_pics where department id is 101.
Does anybody know how to parse it with foreach?
Reinventing the wheel, are we? Why not simply use:
$jsonObj = json_decode($jsonString);//returns stdClass instance, just an object
$jsonArr = json_decode($jsonString, true);//converts object to associative array
Read more on json_decode here... It's quite easy to use, really
If you decode the data to an array, you could loop through the data like so
while($item = array_shift($jsonArr))
{
foreach ($item as $key => $value)
{
echo $key.' => '.$value."\n";
}
}
Or simply use any old for/foreach loop on an object, its a traversable object anyway (though it doesn't implement the Traversable interface)
First step is to convert to an array
$data = json_decode($json);
Once you've got the array, you can then loop through it and check the values
$keepers = array();
foreach ($data as $item) {
if ($item->placement->department_id == 101) {
$keepers[] = $item;
}
}
Use json_decode
$arr = json_decode($jsonstring, true);
then use foreach loop
foreach($arr as $val) {
if($val['placement']['department_id'] == "101") {
//display what u want
}
}
Probably something like:
$data = json_decode($your_json);
foreach($data as $object) {
echo 'This is the name: ' . $object->name . PHP_EOL ;
}
$data = json_decode($json, true)
Then whatever info you want out you get out with the foreach loop
foreach ($data->id as $id)
{
echo $id;
}
With that you can set any variable like $data->nik as $nik or whatever you want then echo them back
usr this
foreach ($data->id as $id)
{
echo $id;
}
