Getting key/value from JSON - php

We are working with an API that brings back JSON in this format:
[
{
"Id": "d7526186-361c-e611-80da-00155df41a0a",
"LogicalName": "contact",
"Attributes": [
{
"Key": "customertypecode",
"Value": {
"Value": 1
}
},
{
"Key": "merged",
"Value": false
},
{
"Key": "territorycode",
"Value": {
"Value": 1
}
}
],
"EntityState": null,
"FormattedValues": [
{
"Key": "customertypecode",
"Value": "Default Value"
},
{
"Key": "address2_addresstypecode",
"Value": "Default Value"
},
{
"Key": "merged",
"Value": "No"
},
{
I am currently using foreach to organise this into a new, cleaner array - but the code base is getting rather large.
What would be the cleanest way of getting specific values based on specifying a key name?
Thanks so much for your help.

First using json_decode to convert to an array, then you can access it in any way you would a normal multi dimensional array... e.g.
$array = array(
"foo" => "bar",
42 => 24,
"multi" => array(
"dimensional" => array(
"array" => "foo"
)
)
);
var_dump($array["foo"]);
var_dump($array[42]);
var_dump($array["multi"]["dimensional"]["array"]);

php echo from a start point to a end point

I have built a php site that takes code from a page using GET, and then echos it to the current page, but it exports text like this,
{ "selection13": [ { "name": "L" }, { "name": "100%\nA" } ], "selection7": [ { "name": "S" }, { "name": "100%\nA" } ], "selection8": [ { "name": "SS" }, { "name": "100%\nA" } ], "selection9": [ { "name": "SP" }, { "name": "100%\nA" } ], "selection10": [ { "name": "P" }, { "name": "100%\nA" } ], "selection11": [ { "name": "A" }, { "name": "100.00%\nA+" } ], "selection12": [ { "name": "H", "selection5": [ { "name": "T }, { "name": "100.00%\nA+" } ] }, { "name": "100.00%\nA+", "selection5": [ { "name": "T" }, { "name": "100.00%\nA+" } ] } ] }
I need to organizes it in to categorizes like, {L},{100%), here is the code I am currently using,
<?php
$params = http_build_query(array(
"api_key" => "()",
"format" => "json"
));
$result = file_get_contents(
'(url)'.$params,
false,
stream_context_create(array(
'http' => array(
'method' => 'GET'
)
))
);
echo gzdecode($result);
?>
Your script is outputting JSON but there appears to be a few issues with the data itself that need to be addressed first.
The next to the last "name": "T is missing a closing quote.
Section 12 has an inconsistent organization compared to the other sections. Can a section be a child of another section or is this an error?
"selection11": [
{
"name": "A"
},
{
"name": "100.00%\nA+"
}
],
"selection12": [
{
"name": "H",
"selection5": [
{
"name": "T"
},
{
"name": "100.00%\nA+"
}
]
},
{
"name": "100.00%\nA+",
"selection5": [
{
"name": "T"
},
{
"name": "100.00%\nA+"
}
]
}
]
These 2 issues need to be fixed in the JSON data you are retrieving first.
From there, the best way to reorganize this is to convert it to an array using json_decode.
$json = gzdecode($result);
$resultArray = json_decode($json);
I can't tell from your question exactly how you want to reorganize the data but use one or more of the builtin array functions to get the data in the structure you want. If you need to output it in JSON, use json_encode on the manipulated array to get the final data format. More specific help can be provided if you can be more clear on want output structure you are looking for and the format (does it need to be JSON or something else).

Better way to iterate multidimensional array of unknown complexity from API than a dozen foreach loops in PHP

I am getting an array from an API that varies in number of levels but follows the same basic structure - here is a truncated sample as this particular repsonse is 25K lines:
{
"Rows": {
"Row": [
{
"Header": {
"ColData": [
{
"value": "Ordinary Income/Expenses"
},
{
"value": ""
}
]
},
"Rows": {
"Row": [
{
"Rows": {},
"Summary": {
"ColData": [
{
"value": "Gross Profit"
},
{
"value": ""
}
]
},
"type": "Section"
},
{
"Header": {
"ColData": [
{
"value": "Income"
},
{
"value": ""
}
]
},
"Rows": {
"Row": [
{
"Header": {
"ColData": [
{
"value": "40000 Sales Income",
"id": "31"
},
{
"value": ""
}
]
},
"Rows": {
"Row": [
{
"Rows": {
"Row": [
{
"ColData": [
{
"value": "2022-01-24"
},
{
"value": "Invoice",
"id": "148774"
},
{
"value": "208232"
},
{
"value": "Hyatt:#211102",
"id": "7568"
},
{
"value": "JN",
"id": "4100000000000368107"
},
{
"value": "CAPTIVE AIRE"
},
{
"value": "11000 Accounts Receivable",
"id": "80"
},
{
"value": "38748.00"
},
{
"value": "38748.00"
}
],
"type": "Data"
},
I need to traverse the json, and where there is data in both [Header][ColData][value] AND [Header][ColData][id] extract the value, id (in this snippet "value": "40000 Sales Income", "id": "31") and the data that immediately follows the "value"/"id" in [Rows][Row][Rows][Row][ColData] (in this snippet starting with "ColData": [{"value": "2022-01-24"...)
[Rows][Row][Rows][Row][ColData] will have one to a few hundred subarrays. I can extract the data from the subarrays once they are found - it's just managing the varying depths of the array that is warping my brain.
[Rows][Row][Rows][Summary] can be discarded as well.
I have tried multiple foreach loops - but by time I get 5 or 6 levels deep it gets very confusing. The number of Header sections varies depending on the report type. The [Rows][Row] nesting is multiple layers deep... I'm sure there has to be a better way than nesting foreach loops...
This is what I've come up with. Kindly modify it to meet your need.
$array = json_decode($json, true);
function traverse_some_array($array){
$result = [];
foreach($array['Rows']['Row'] ?? [] as $row){
if( !empty($row['Header']['ColData']) ){
foreach($row['Header']['ColData'] as $coldata){
if( isset($coldata['value'], $coldata['id']) ){
// there is data in both [Header][ColData][value] AND [Header][ColData][id]
// extract the value, id (in this snippet "value": "40000 Sales Income", "id": "31")
$extract_data = [
'value' => $coldata['value'],
'id' => $coldata['id']
];
// the data that immediately follows the "value"/"id" in [Rows][Row][Rows][Row][ColData]
$immediate_coldata = $row['Rows']['Row'] ?? [];
// you can do what ever you want with the results, eg return it or push it to a result array
$result[] = [
'extract_data' => $extract_data,
'immediate_coldata' => $immediate_coldata
];
}else{
// continue traversing the array
$result = array_merge($result, traverse_some_array($row));
}
}
}
}
return $result;
}
print_r(traverse_some_array($array));

Yii2 convert an object with keys to an array of form 0,1,2,3,

Am using Yii2 AuthManager to get a persions permissions using
return [
"permissions" => \Yii::$app->authManager->getPermissionsByUser(
Yii::$app->user->identity->id ),
]
The above returns data of the form
"permissions": {
"permission1":{
"type": "2",
"name": "permission1",
},
"permission2":{
"type": "2",
"name": "permission2",
}
..................
}
What i was looking for is an outpiut like this
"permissions": {
0:{
"type": "2",
"name": "permission1",
},
1:{
"type": "2",
"name": "permission2",
}
..................
}
How do i convert the above to an array of values not with the keys to get the desired output?
Try this:
return [
"permissions" => array_values(\Yii::$app->authManager->getPermissionsByUser(
Yii::$app->user->identity->id )),
];
Assuming you get the result in $permissions
foreach ($permissions as $key => $value){
$new_perm[] = $value;
}
in $new_perm you should obtain the result you need

How to parse JSON decoded by cURL on PHP

I 'm trying to make some pages with php and curl using REST API. I can connect application and get all values as JSON format with curl on PHP. But, I can not parse values what i want.
I used this PHP commands for decode json values ;
$data = json_decode($response, true);
print_r($data);
When I use this command i'm getting returning value like this ;
Array ( [links] => Array ( ) [content] => Array ( [0] => Array (
[#type] => ConsumerEnt [links] => Array ( [0] =>
Array ( [#type] => link [rel] => GET: Request [href] =>
http.....
) => Array ...etc
There are arrays inside arrays.. I could not find how to parse values i want. You can see values i want at following json codes;
Do you have any idea how it can be possible ?
Than
You can see Decoded JSON by http://json.parser.online.fr/

I guess i solved my issue like this ;
$data = json_decode($response, true);
print_r($data);
$j=count($data["content"]);
for ( $say=0 ; $say < $j ; $say++ )
{
print $data["content"][$say]["name"];
}
as a result i can list my products ;
Product1
Product2
Product3

Creating a PHP object with out the use of a key?

I've got a request to present the data in the following format as a JSON feed:
{
"id": "123",
"info": {
"code": "ZGE",
"description": "test1",
"type": "AVL",
"date": "09/08/2012"
}
},
{
"id": "456",
"info": {
"code": "ZDN",
"description": "test2",
"type": "CLR",
"date": "16/02/2012"
}
}
However in my PHP code, I think I need to have a key itterator - but I end up with this format:
{
"0": {
"id": "123",
"info": {
"code": "ZGE",
"description": "test1",
"type": "AVL",
"date": "09/08/2012"
}
},
"1": {
"id": "456",
"info": {
"code": "ZDN",
"description": "test2",
"type": "CLR",
"date": "16/02/2012"
}
}
}
Any ideas on how to build the first data set with out having the index iterator?
simple create an array of objects, no need for the key (notice the [ ] surrounding your list)
json.txt
[{
"id": "123",
"info": {
"code": "ZGE",
"description": "test1",
"type": "AVL",
"date": "09/08/2012"
}
},
{
"id": "456",
"info": {
"code": "ZDN",
"description": "test2",
"type": "CLR",
"date": "16/02/2012"
}
}]
example.php
<?php
$data = json_decode(file_get_contents('./json.txt'));
?>
It can be built like this:
$arr = array(
array(
'id' => 123,
'info' => array(
'code' => 'ZGE',
'description' => 'test1',
'type' => 'AVL'
)
),
array(
'id' => 456,
'info' => array(
'code' => 'ZDN',
'description' => 'test2',
'type' => 'CLR'
)
)
);
echo json_encode($arr);
Outputs
[
{
"id": 123,
"info": {
"code": "ZGE",
"description": "test1",
"type": "AVL"
}
},
{
"id": 456,
"info": {
"code": "ZDN",
"description": "test2",
"type": "CLR"
}
}
]
the JSON format you've specified in the first example (ie the requested format) is not valid JSON.
A valid JSON string must evaluate to a single Javascript object; the example you've given evaluates to two Javascript objects, separated by a comma. In order to make it valid, you would need to either enclose the whole thing in square brackets, to turn it into a JS array or enclose it in curly braces, and give each of the two objects a key.
The PHP code you've written is doing the second of these two options. It is therefore generating valid JSON code, about as close to the original request as could be expected while still being valid.
It would help if you'd shown us the PHP code that you've used to do this; without that, I can't really give you advice on how to improve it, but if you want to switch to the square bracket notation, all you need is to put your PHP objects into an unkeyed array, and json_encode() should do it all for you; you shouldn't need to use a keyed array or an iterator for that.
The only reason json_encode should produce the output you're seeing is adding another named key to the array that you're passing to json_encode, by default it should work as you want:
$json = '[
{
"id": "123",
"recall_info": {
"code":"ZGE",
"description": "test1",
"type": "AVL",
"date": "09/08/2012"
}
},
{
"id": "123",
"recall_info": {
"code": "ZDN",
"description": "test2",
"type": "CLR",
"date": "16/02/2012"
}
}
]';
$php = array(
(object) array(
'id' => '123',
'recall_info' => (object) array(
'code' => 'ZGE',
'description' => 'test1',
'type' => 'AVL',
'date' => '09/08/2012'
)
),
(object) array(
'id' => '123',
'recall_info' => (object) array(
'code' => 'ZGE',
'description' => 'test2',
'type' => 'CLR',
'date' => '16/02/2012'
)
)
);
var_dump(json_encode($php));
