How to modify json key - php

I need some help to reorder the data in a json file.
I have these few lines :
foreach($rows as $row) {
$data[] = array(
"$row[0]" => array(
"name" => "$row[1]",
"value" => "$row[2]",
"conso" => "$row[3]",
"ml" => "$row[4]"
)
);
}
$data = json_encode($data, JSON_FORCE_OBJECT);
This function allows me to obtain something like this :
This function allows me to obtain something like this :
{
"0": {
"tata": {
"name": "name_01",
"value": "value_01",
"conso": "conso_01",
"ml": "ml_01"
}
},
"1": {
"toto": {
"name": "name_02",
"value": "value_02",
"conso": "conso_02",
"ml": "ml_02"
}
}
}
I would like something like that :
{
"tata": {
"name": "name_01",
"value": "value_01",
"conso": "conso_01",
"ml": "ml_01"
},
"toto": {
"name": "name_02",
"value": "value_02",
"conso": "conso_02",
"ml": "ml_02"
}
}

Get rid of a layer of array, and specify the key you want. You also don't need to quote all the variables like that.
foreach($rows as $row) {
$data[$row[0]] = array(
"name" => $row[1],
"value" => $row[2],
"conso" => $row[3],
"ml" => $row[4]
);
}
$data = json_encode($data, JSON_FORCE_OBJECT);

PHP convert CSV to JSON multi level

I have a CSV data looks like this :
ps.csv
id|firstName|lastName|address|extId|extName
001|Kapil|Parames|address01|AA01|AA
002|David|Vuitton|address01|AA02|AA
002|David|Vuitton|address02|BB02|BB
003|Jean|Paul|address01|AA03|AA
And i need an output JSON to look like this :
[
{
"id": "001",
"firstName": "Kapil",
"lastName": "Parames",
"address": [{
"address": "address01"
}],
"ext": [{
"extId": "AA01",
"extName": "AA"
}]
},
{
"id": "002",
"firstName": "David",
"lastName": "Vuitton",
"address": [{
"address": "address01"
},
{
"address": "address02"
}
],
"ext": [{
"extId": "AA02",
"extName": "AA"
},
{
"extId": "BB02",
"extName": "BB"
}
]
},
{
"id": "003",
"firstName": "Jean",
"lastName": "Paul",
"address": [{
"address": "address01"
}],
"ext": [{
"extId": "AA03",
"extName": "AA"
}]
}
]
I can convert it to JSON. But the problem is i would like to add "address" and "extId", "extName" into multi level array if the person already exists in the list.
So following PHP code is working for me :
$csv = file('ps.csv');
$csvArray = [];
foreach ($csv as $line) {
$csvArray[] = str_getcsv($line, '|', ',');
}
$jsonArray = [];
for ($i = 1; $i < count($csvArray); $i++) {
$found = -1;
for ($j = 0; $j < count($jsonArray); $j++) {
if (in_array($csvArray[$i][0], $jsonArray[$j])) {
$found = $j;
}
}
if ($found < 0) {
$jsonArray[] = array(
'id' => $csvArray[$i][0],
'firstName' => $csvArray[$i][1],
'lastName' => $csvArray[$i][2],
'address' => array(
[
'address' => $csvArray[$i][3]
]
),
'ext' => array(
[
'extId' => $csvArray[$i][4],
'extName' => $csvArray[$i][5]
]
)
);
} else {
$addressArray = array(
'address' => $csvArray[$i][3]
);
$extArray = array(
'extId' => $csvArray[$i][4],
'extName' => $csvArray[$i][5]
);
array_push($jsonArray[$found]['address'], $addressArray);
array_push($jsonArray[$found]['ext'], $extArray);
}
}
echo '<pre>';
echo json_encode($jsonArray, JSON_PRETTY_PRINT);
echo '</pre>';
Is that correct or is there any other way to do ?

PHP change a function from from loops to recursion

I have the following JSON object:
{
"id": 1,
"name": null,
"block": {
"type": "none",
"descends": [
{
"operation":"sum",
"descends":[
{
"label":2,
"value":false
}
]
},
{
"label": 1,
"value": 3,
},
{
"label": 2,
"value": 2
}
],
"label": 1,
"value": true
}
}
I want to collect all the label and value attributes and store them in an array, so I created the following function:
public function collectValues($arr){
$finalValues = [];
foreach($arr as $key => $element){
if($key=='block'){
foreach($element as $key2 => $block){
if($key2=='descends'){
foreach($block as $key3 => $node_block){
if($key3=='descends'){
foreach($node_block as $key4 => $anotherNode){
if($key4 == 'descends'){
foreach($anotherNode as $finalNode){
$finalValues [] = array('lable'=>$finalNode->label, 'value' =>$finalNode->value);
}
}
}
}
else{
$finalValues [] = array('lable' => $node_block->label, 'value' => $node_block->value);
}
}
}
}
$finalValues [] = array('lable'=> $element->label, 'value' => $element->value);
}
}
return $finalValues;
}
The function works and I get the following:
[
{
"lable": 2,
"value": false
},
{
"lable": 1,
"value": 3
},
{
"lable": 2,
"value": 2
},
{
"lable": 1,
"value": true
}
]
The problem is that the JSON object can contain more descends like:
{
"id": 1,
"name": null,
"block": {
"type": "none",
"descends": [
{
"operation":"sum",
"descends":[
{
"operation":"sum",
"descends":[
{
"label":2,
"value":false
}
],
"label":2,
"value":false
}
]
},
{
"operation":"sum",
"descends":[
{
"label":2,
"value":false
}
],
"label": 1,
"value": 3,
},
{
"label": 2,
"value": 2
}
],
"label": 1,
"value": true
}
}
This means I will have to add more foreach loops. A good way to handle such a situation is by using recursive. How can I transform the function above into a recursive one?
Your looped function does not make sense to change. Easier to rewrite from scratch
Here is my use case for recursion. Maybe there is an easier option, but I didn’t chase optimization
$array = json_decode($json, true); //in $json your JSON)
$result = []; // array for result
checkLabel($array, $result);
print_r($result);
function checkLabel(array $array, &$result){
//first check every element on nested array
foreach ($array as $key => $value){
if (is_array($value)) {
//if found call recursive function
checkLabel($value, $result);
}
}
//then check 'label' key.. its mean we have attribute
if (array_key_exists('label', $array)) {
//save it
$result[] = [
'label' => $array['label'],
'value' => $array['value']??'' //if have label but without value)
];
}
}

Include variable into array if not empty inside foreach

Include the name variable if the value is not empty inside the foreach. I tried this method code below but it include outside the array. I want to include within the array.
Sample Code:
$load_array = array();
foreach($stmt->fetchAll() as $row){
$load_array[] = array(
'name' => $row['name'],
'start_location' => array(
'address' => $row['start_address'],
'coords' => array (
'lat' => floatval($row['start_lat']),
'lng' => floatval($row['start_lng']),
),
),
);
if(!empty($row['shift_start'])) { $load_array['shift_start'] = $row['shift_start'];}
if(!empty($row['shift_end'])) { $load_array['shift_end'] = $row['shift_end'];}
}
return json_encode($load_array);
Output code above:
{
"0": {
"name": "Ramon Macger",
"start_location": {
"address": "76 Spilman Street GORSGOCH SA40 8ZB",
"coords": {
"lat": 42.45188,
"lng": -83.12829
}
}
},
"1": {
"name": "Roberto",
"start_location": {
"address": "76 Spilman Street GORSGOCH SA40 8ZB",
"coords": {
"lat": 42.45188,
"lng": -83.12829
}
}
},
"shift_start": "14:00",
"shift_end": "17:00"
}
The output should be like this:
{
"0": {
"name": "Ramon Macger",
"start_location": {
"address": "76 Spilman Street GORSGOCH SA40 8ZB",
"coords": {
"lat": 42.45188,
"lng": -83.12829
}
},
"shift_start": "14:00",
"shift_end": "17:00"
},
"1": {
"name": "Roberto",
"start_location": {
"address": "76 Spilman Street GORSGOCH SA40 8ZB",
"coords": {
"lat": 42.45188,
"lng": -83.12829
}
},
"shift_start": "14:00",
"shift_end": "17:00"
},
}
The shift_start and shift_end should be within the array not outside. My code is working in 1 array only and not on the foreach. However, it doesn't working within for each.
You need to add shift_start and shift_end values into the data array before you push it into $load_array. Something like this:
foreach($stmt->fetchAll() as $row){
$data = array(
'name' => $row['name'],
'start_location' => array(
'address' => $row['start_address'],
'coords' => array (
'lat' => floatval($row['start_lat']),
'lng' => floatval($row['start_lng']),
),
),
);
if(!empty($row['shift_start'])) {
$data['shift_start'] = $row['shift_start'];
}
if(!empty($row['shift_end'])) {
$data['shift_end'] = $row['shift_end'];
}
$load_array[] = $data;
}

Php json_encode array and object array

I need to create a json with this format:
{
"reservs": [
{
"ResId": "58",
"time": "2020-05-15 19:41:50",
"boxEntering": null,
"boxClosing": null,
"active": "1",
"UserId": "29",
"BoxId": "4",
"boxPlace": null,
"box": {
"id": "4",
"Nom": "Hortillonages",
"Lat": "49.8953",
"Lng": "2.31034",
"place": "0",
"placeMax": "9"
}
}
]
}
in entries, a $header who check the user token(not use for my problem)
$table the table returned from PDO::FETCHASSOC from sql SELECT request
My php code:
function generateJson($table, headerChecker $header){
$final = array();
foreach ($table as $item) {
$box = array(
"id" => $item["id"],
"Nom" => $item["Nom"],
"Lat" => $item["Lat"],
"Lng" => $item["Lng"],
"place" => $item["place"],
"placeMax" => $item["placeMax"]
);
$reserv = array(
"ResId" => $item["ResId"],
"time" => $item["time"],
"boxEntering" => $item["boxEntering"],
"boxClosing" => $item["boxClosing"],
"active" => $item["active"],
"UserId" => $item["UserId"],
"BoxId" => $item["BoxId"],
"boxPlace" => $item["boxPlace"],
);
$reserv["box"] = $box;
array_merge($final,$reserv);
}
$arr = array("reservs" => $table);
$header->tokenJson($arr);
echo json_encode($arr);
}
I have this result
{"reservs": [
{
"ResId": "58",
"time": "2020-05-15 19:41:50",
"boxEntering": null,
"boxClosing": null,
"active": "1",
"UserId": "29",
"BoxId": "4",
"boxPlace": null,
"id": "4",
"Nom": "Hortillonages",
"Lat": "49.8953",
"Lng": "2.31034",
"place": "0",
"placeMax": "9",
"QRID": "",
"boxToken": ""
}]
}
I think the Json format eror is in the array_merge function.
What add array function can I use to not remove the Box object
Your problem is that you are not assigning the return of array_merge and using the wrong variable $table. Just dynamically append to $final:
foreach ($table as $item) {
// this all appears good
//
$reserv["box"] = $box;
$final[] = $reserv; // append to $final
}
$arr = array("reservs" => $final); // use $final
$header->tokenJson($arr);
echo json_encode($arr);
Merge the new $reserv into $final and assign it to $final, then use $final.
Try this one
function generateJson($table, headerChecker $header){
$final = array();
foreach ($table as $item) {
$box = array(
"id" => $item["id"],
"Nom" => $item["Nom"],
"Lat" => $item["Lat"],
"Lng" => $item["Lng"],
"place" => $item["place"],
"placeMax" => $item["placeMax"]
);
$reserv = array(
"ResId" => $item["ResId"],
"time" => $item["time"],
"boxEntering" => $item["boxEntering"],
"boxClosing" => $item["boxClosing"],
"active" => $item["active"],
"UserId" => $item["UserId"],
"BoxId" => $item["BoxId"],
"boxPlace" => $item["boxPlace"],
);
$reserv["box"] = $box;
$final[] = $reserv;
}
$arr = array("reservs" => $final);
$header->tokenJson($arr);
echo json_encode($arr);
}

Add array elements in an array position

How can I add an array to array position:
Something like a:
<?php
$newArr = array('email' => array("id" => "5678", "token" => "fghjk"));
$arr = array(
"auth"=>
array(
'users'=>
array(
'id' =>"456yhjoiu",
'token' => "asdfghjkrtyui678"
)
)
);
somefunction($arr['auth'], $newArr);
I've tried array_push() but it added zero (0) before 'email' instead.~
I'm doing this to get a json output, something like this:
}
"auth": {
"users": {
"id": "456yhjoiu",
"token": "asdfghjkrtyui678"
},
"email": {
"id": "5678",
"token": "fghjk"
}
}
}
but I have this output:
{
"auth": {
"users": {
"id": "456yhjoiu",
"token": "asdfghjkrtyui678"
},
"0": {
"email": {
"id": "5678",
"token": "fghjk"
}
}
}
$data = ['auth' => array_merge($arr['auth'], $newArr)];
or old array notation <= PHP5.3
$data = array('auth' => array_merge($arr['auth'], $newArr));
