I wrote the code that selects data from database, groups array by 2 parameters (match_day and competition_id) and generates JSON
foreach ($result as $res) {
$day = date('d', $res["match_start_time"]);
$json["response"][] = array(
"competition_id" => $res["competition_id"],
"match_start_time" => $res["match_start_time"],
"match_day" => $day
);
}
$arr = array();
$arr["items"] = array();
foreach($json["response"] as $key => $item)
{
if(!isset($arr['items'][$item['match_day']][$item['competition_id']])){
$arr['items'][$item['match_day']][$item['competition_id']] = array();
$arr['items'][$item['match_day']][$item['competition_id']]['league'] = $item['competition_id'];
$arr['items'][$item['match_day']][$item['competition_id']]['day'] = $item['match_day'];
}
$arr['items'][$item['match_day']][$item['competition_id']]['matches'][] = $item;
}
$arr['items'] = array_values($arr['items']);
echo json_encode($arr);
This code gives me following JSON
{
"items": [
{
"cuefa": {
"league": "cuefa",
"day": "01",
"matches": [
{
"competition_id": "cuefa",
"match_start_time": "1285873500"
}
]
}
},
{
"cuefa": {
"league": "cuefa",
"day": "30",
"matches": [
{
"competition_id": "cuefa",
"match_start_time": "1285866000"
}
]
}
}
]
}
I can't remove competition_id inside of items array. How to change code to get following JSON?
{
"items": [
{
"block": [
{
"league": "cuefa",
"day": "01",
"matches": [
{
"competition_id": "cuefa",
"match_start_time": "1285873500"
}
]
}
]
},
{
"block": [
{
"league": "cuefa",
"day": "30",
"matches": [
{
"competition_id": "cuefa",
"match_start_time": "1285866000"
}
]
}
]
}
]
}
Add this before the json_encode:
foreach ($arr['items'] as &$item) {
$item = array('block' => array_values($item));
}

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)
];
}
}
i have below json data
{
"data": [
{
"minggu a": "2",
"total a": "377033"
},
{
"minggu b": "1",
"total b": "136615"
}
]
and this is the code i made in controller
$satu= $this->model->db_week_resTender();
$arr = [];
foreach($satu as $val){
$arr['data'][] = array(
'minggu' => $val['minggu'],
'total' => $val['total']
);
}
$response = $this->set_response($arr,200);
}
how to concatenate below json data
here I issue data with a limit of 2.
{
"data": [
{
"minggu a": "2",
"total a": "377033"
"minggu b": "1",
"total b": "136615"
},
]
}
$data = '{
"data": [
{
"minggu a": "2",
"total a": "377033"
},{
"minggu b": "1",
"total b": "136615"
}
]
}';
$decoded_satu=json_decode($data,true);
$arr = [];
foreach($decoded_satu['data'] as $key=> $val){
foreach ($val as $subkey => $subvalue) {
$arr['data'][$subkey] = $subvalue;
}
}
$finalArray = json_encode($arr);
echo "<pre>";print_r($finalArray) ;die;
foreach($statu as $index => $val){
$arr['data'][$index] = $val;
}
This should give the result you have posted at the end.
In PHP, I have learned that to be able to get values from an object is to do something like this:
$objResult->{"RESP"}->{"DATA"}->{"F_NAME"}
However, for the data below, how will I be able to get the name "NO_1"?
Since its in an array, I want to be able to extract the data in it, and I'm thinking of getting the name of it first.
{
"SAMPLE": [
{
"NO_1": [
{
"RESULT": [
{
"NUMBER": 1,
"F_NAME": "JOHN",
"L_NAME": "SMITH"
},
{
"NUMBER": 2,
"F_NAME": "WILL",
"L_NAME": "JONES"
}
]
}
]
},
{
"NO_2": [
{
"RESULT": [
{
"NUMBER": 3,
"F_NAME": "MARY",
"L_NAME": "JANE"
},
{
"NUMBER": 4,
"F_NAME": "NEIL",
"L_NAME": "STRONG"
}
]
}
]
}
]
}
Any ideas?
There are two ways to get this. Either you can access direct index or iterate the loop to get all the members. Below is the example you can apply checks for error handling while accessing array indexes.
<?php
$json = '{
"SAMPLE": [
{
"NO_1": [
{
"RESULT": [
{
"NUMBER": 1,
"F_NAME": "JOHN",
"L_NAME": "SMITH"
},
{
"NUMBER": 2,
"F_NAME": "WILL",
"L_NAME": "JONES"
}
]
}
]
},
{
"NO_2": [
{
"RESULT": [
{
"NUMBER": 3,
"F_NAME": "MARY",
"L_NAME": "JANE"
},
{
"NUMBER": 4,
"F_NAME": "NEIL",
"L_NAME": "STRONG"
}
]
}
]
}
]
}';
$arr = json_decode($json,TRUE);
echo $arr['SAMPLE'][0]['NO_1'][0]['RESULT'][0]['F_NAME']; // Direct access
foreach ($arr as $key => $result){ // iterate in loop
foreach ($result as $key => $no) {
foreach ($no['NO_1'] as $key => $res) {
foreach ($res['RESULT'] as $key => $name) {
echo $name['F_NAME'];
}
}
}
}
die;

This is my JSON Response came from an URL API. I use GuzzleHttp\Client and json_decode() inorder to manage.
[{
"INDEX_ID": "0",
"NOTES": "0; Farming"
},
{
"INDEX_ID": "1",
"NOTES": "Fruit Name; List of Fruits;"
},
{
"INDEX_ID": "2",
"NOTES": "Apple"
},
{
"INDEX_ID": "3",
"NOTES": "Orange"
},
{
"INDEX_ID": "4",
"NOTES": "Grapes"
},
{
"INDEX_ID": "5",
"NOTES": "Mango"
},
{
"INDEX_ID": "6",
"NOTES": "Animal Name; List of Animal;"
},
{
"INDEX_ID": "7",
"NOTES": "Pig"
},
{
"INDEX_ID": "8",
"NOTES": "Goat"
},
{
"INDEX_ID": "9",
"NOTES": "Cow"
}]
But I only need to save list of Fruits in my logfile. Can someone help me how to exclude the other json parameters and get only the particular json parameters using foreach loop or any method inorder to get that result.
I just want it to be like this:
[
{
"NOTE_NO." : "001",
"CATEGORY" : "FRUITS",
"LISTS_TO_BUY" : [
{
"FRUITS": "Apple"
},
{
"FRUITS": "Orange"
},
{
"FRUITS": "Grapes"
},
{
"FRUITS": "Mango"
}
]
}
]
He're my codes so far:
$response_body = json_decode($json_response, true);
$json_new_param = [];
foreach ($response_body as $value) {
$json_new_param[] = [
'FRUITS' => $value['NOTES']
];
}
$header = [
[
'NOTE_NO.' => '001',
'CATEGORY' => 'FRUITS',
'LISTS_TO_BUY' => $json_new_param
]
];
echo json_encode($header);
$json_response is the response given above.
You might use array_reduce to return an array where the key will be the first word from the value using implode which has this structure: "NOTES": "Fruit Name; List of Fruits;". The key for this would then be "Fruits".
During the array_reduce keep track of the current key using a variable $currKey
At the end you could then get the data by using "FRUIT" (Which is the first word) as the array key: $response_body["FRUIT"]
$response_body = json_decode($json_response, true);
$currKey = "0";
$response_body = array_reduce($response_body, function ($carry, $item) use (&$currKey){
if (strpos($item['NOTES'], 'Name; List') !== false) {
$currKey = strtoupper(explode(" ", $item["NOTES"], 2)[0]);
return $carry;
}
$carry[$currKey][] = ["FRUITS" => $item["NOTES"]];
return $carry;
});
$result = [
[
"NOTE_NO" => "001",
"CATEGORY" => ($name = "FRUITS"),
"LISTS_TO_BUY" => $response_body["FRUIT"]
]
];
echo json_encode($result, JSON_PRETTY_PRINT);
That will result in:
[
{
"NOTE_NO": "001",
"CATEGORY": "FRUITS",
"LISTS_TO_BUY": [
{
"FRUITS": "Apple"
},
{
"FRUITS": "Orange"
},
{
"FRUITS": "Grapes"
},
{
"FRUITS": "Mango"
}
]
}
]
Demo
Try this code .
$json_new_param = [];
$fruitFlag = false;
foreach ($response_body as $value) {
if(strpos($value['NOTES'],'Fruit Name') !== false){
$fruitFlag = true;
continue;
}
if(strpos($value['NOTES'],'Animal Name') !== false){
$fruitFlag = false;
}
if($fruitFlag == true){
$json_new_param[] = [
'FRUITS' => $value['NOTES']
];
}
}
echo json_encode($json_new_param, JSON_PRETTY_PRINT);
I need a help. I'm looking for a solution for this problem!
I have a file which contains the following pattern:
Brazil|SaoPaulo|Diadema|RuadaFe Brazil|SaoPaulo|Diadema|RuadoLimoeiro
Brazil|SaoPaulo|SaoCaetano|RuadasLaranjeiras
Brazil|Parana|Curitiba|ComendadorAraujo
USA|NewJersey|JerseyCity|WhashingtonBoulervard
USA|NewJersey|JerseyCity|RiverCourt
Which should bring after some array key implementation, something like this (after apply json_encode call on php):
{
"name": "Brazil",
"children": [
{
"name": "SaoPaulo",
"children": [
{
"name": "Diadema",
"children": [
{"name": "RuadaFe"},
{"name": "RuadoLimoeiro"}
]
},
{
"name": "SaoCaetano",
"children": [
{"name": "RuadasLaranjeiras"}
]
},
]
"name": "Parana",
"children": [
{
"name": "Curitiba",
"children": [
{"name": "ComendadorAraujo"}
]
}
]
},
"name":"USA",
"children":[
{
"name": "NewJersey",
"children": [
{
"name": "JerseyCity",
"children": [
{"name": "WhashingonBoulevard"},
{"name": "RiverCourt"}
]
}
]
}
]
}
]
And keep going and going (and even more deeper too).
Please, help me team... thanks in advance.
Here what I get until now:
Array
(
[Brazil] => Array
(
[SaoPaulo] => Array
(
[Diadema] => Array
(
[RuadoLimoeiro] =>
)
[SaoCaetano] => Array
(
[RuadasLaranjeiras] =>
)
)
[Parana] => Array
(
[Curitiba] => Array
(
[ComendadorAraujo] =>
)
)
)
[USA] => Array
(
[NewJersey] => Array
(
[JerseyCity] => Array
(
[WhashingtonBoulervard] =>
[RiverCourt] =>
)
)
)
)
And here is the json encoded:
{
"Brazil":{
"SaoPaulo":
{"Diadema":
{"RuadoLimoeiro":null},
"SaoCaetano":{"RuadasLaranjeiras":null}
},
"Parana":
{"Curitiba":
{"ComendadorAraujo":null}
}
},
"USA":{
"NewJersey":{
"JerseyCity":{
"WhashingtonBoulervard":null,
"RiverCourt":null}
}
}
}
As you can see, the "names" and "child" is missing because is not an array key structure, also something is wrong, because I'm missing some values on SaoPaulo.
Here is the function:
foreach($strings as $string) {
$parts = array_filter(explode('|', $string));
$ref = &$result;
foreach($parts as $p) {
// echo $p;
if(!isset($ref[$p])) {
$ref[$p] = array();
// $ref[$p] = array("name"=>$p);
}
$ref = &$ref[$p];
}
$ref = null;
}
-------------------------------- AFTER SOME ANSWERS --------------------------
{
"name": "Brazil(country)",
"children": [
{
"name": "SaoPaulo(state)", // only one state
"children": [
{
"name": "Diadema(city)", // only one city
"children": [
{"name": "RuadaFe(street)"}, // two streets under the same city...
{"name": "RuadoLimoeiro(street)"}
]
},
{
"name": "SaoCaetano(city)",
"children": [
{"name": "RuadasLaranjeiras(street)"}
]
},
]
"name": "Parana(state)",
"children": [
{
"name": "Curitiba(city)",
"children": [
{"name": "ComendadorAraujo(street)"}
]
}
]
},...
I put on parentesis the structure (country, state, city, street) just to clarify what i want.
Got it?
It is not outright trivial, but what I did is actually the same as you (the same way as in your edited question), but I also keep track of those arrays to rename the keys. And that's what I do afterwards then:
$separator = [' ', '|'];
$buffer = file_get_contents($file);
$entries = explode($separator[0], $buffer);
$result = [];
$named[] = &$result;
########
foreach ($entries as $entry) {
$each = explode($separator[1], $entry);
$pointer = & $result;
while ($current = array_shift($each)) {
if (!isset($pointer[$current])) {
unset($children);
$children = [];
$named[] = &$children;
########
$pointer[$current] = ['name' => $current, 'children' => &$children];
}
$pointer = & $pointer[$current]['children'];
}
}
foreach($named as $offset => $namedArray) {
$keys = array_keys($namedArray);
foreach($keys as $key) {
$named[$offset][] = &$namedArray[$key];
unset($named[$offset][$key]);
}
}
print_r($result);
See it in action.
You probably might want to modify this by checking in the later foreach if children are empty (leaf-nodes) and then removing the children entry as well.
Here the modified foreach at the end and json output:
foreach($named as $offset => $namedArray) {
$keys = array_keys($namedArray);
foreach($keys as $key) {
if (!$namedArray[$key]['children']) {
unset($namedArray[$key]['children']);
}
$named[$offset][] = &$namedArray[$key];
unset($named[$offset][$key]);
}
}
echo json_encode($result, JSON_PRETTY_PRINT);
Output:
[
{
"name": "Brazil",
"children": [
{
"name": "SaoPaulo",
"children": [
{
"name": "Diadema",
"children": [
{
"name": "RuadaFe"
},
{
"name": "RuadoLimoeiro"
}
]
},
{
"name": "SaoCaetano",
"children": [
{
"name": "RuadasLaranjeiras"
}
]
}
]
},
{
"name": "Parana",
"children": [
{
"name": "Curitiba",
"children": [
{
"name": "ComendadorAraujo"
}
]
}
]
}

},

The only difference I can spot is that the root-nodes are wrapped inside an array in my answer, but it should be trivial to fetch them out there if that really is your issue ;)
Does it solves your problem? Use $inputString to put your real string.
<?php
