How to create a JSON with PHP? - php

I'm looking to order data from a Json file with PHP :
$url = 'data.json';
$json_string = file_get_contents($url);
$json = json_decode($json_string);
$rows = $json->values;
foreach($rows as $row) {
$jsonf .= json_encode(array(
"$row[0]" => array(
"name" => "$row[1]",
"value" => "$row[2]",
"conso" => "$row[3]",
"ml" => "$row[4]"
)
), JSON_UNESCAPED_UNICODE);
}
Unfortunately, with this method, I get a bad result:
{
"DATA_01": {
"name": "name_01",
"value": "value_01",
"conso": "conso_01",
"ml": "ml_01"
}
} {
"DATA_02": {
"name": "name_02",
"value": "value_02",
"conso": "conso_02",
"ml": "ml_02"
}
} {
"DATA_03": {
"name": "name_03",
"value": "value_03",
"conso": "conso_03",
"ml": "ml_03"
}
}
I would rather get something like this:
{
"DATA_01": {
"name": "name_01",
"value": "value_01",
"conso": "conso_01",
"ml": "ml_01"
},
"DATA_02": {
"name": "name_02",
"value": "value_02",
"conso": "conso_02",
"ml": "ml_02"
},
"DATA_03": {
"name": "name_03",
"value": "value_03",
"conso": "conso_03",
"ml": "ml_03"
}
}
Could someone help me solve my problem.
Thank you very much for all the help you can give me.

I am not really sure what you want to accomplish, but I think it is the following:
You get this result because you are putting the json_encode function within a for-loop. put all your detain an array, and encode it after that. Your code will become like this:
foreach($rows as $row) {
$data[] = $row[0];
}
json_encode($data)

Array for subseries on highcharts Drilldown

I'm having some problems generating graphs with drilldown in Highcharts.
I'm using Highcharts to render a pie with drilldown series.
I need to transform this output json
Drilldownseries = [
{
"name": "LAZIO",
"data": [["ROMA", 28]],
"id": "LAZIO"
},
{
"name": "LAZIO",
"data": [["FROSINONE", 218]],
"id": "LAZIO"
},
{
"name": "LAZIO",
"data": [["LATINA", 212]],
"id": "LAZIO"
},
{
"name": "TOSCANA",
"data": [["FIRENZE", 2]],
"id": "TOSCANA"
},
{
"name": "TOSCANA",
"data": [["LIVORNO", 5]],
"id": "TOSCANA"
},
{
"name": "TOSCANA",
"data": [["PISA", 9]],
"id": "TOSCANA"
}
];
to
Drilldownseries = [
{
"name": "LAZIO",
"data": [["ROMA", 28], ["FROSINONE", 218], ["LATINA", 212]],
"id": "LAZIO"
},
{
"name": "TOSCANA",
"data": [["FIRENZE", 2], ["LIVORNO", 5], ["PISA", 9]],
"id": "TOSCANA"
}
];
This is the part of query that populates the array:
...
if($res3)
{
$i = 0;
while ($row = mysqli_fetch_array($res3, MYSQLI_ASSOC))
{
$row3[$i]["name"] = $row["name"];
$row3[$i]["data"] = [[$row["subname"],$row["data"]]];
$row3[$i]["id"] = $row["id"];
$i++;
};
$row3 = json_encode($row3,JSON_NUMERIC_CHECK);
};
I'd prefer to extract the array with php well formed, but should be the same tranform the json.
PHP 7.2
Highcharts 6.1.1
for benefit of all, this is my solution. Code refined should be appreciated :)
First removed square brackets in code below
$row3[$i]["data"] = [$row["subname"],$row["data"]];
then create the new array so
$repl = array();
$i = 0;
foreach ($row3 as $value) {
if (!isset($repl[$i]['id'])) {
$repl[$i]['id'] = $value['id'];
$repl[$i]['name'] = $value['name'];
$repl[$i]['data'] = [$value['data']];
} elseif (($repl[$i]['id']) <>$value['id']) {
$i++;
$repl[$i]['id'] = $value['id'];
$repl[$i]['name'] = $value['name'];
$repl[$i]['data'] = [$value['data']];
} else {
array_push($repl[$i]['data'], $value['data']);
}
}
$resultx = json_encode($repl,JSON_NUMERIC_CHECK);

Access variable Array Data PHP

i have the following Array Structure from Facebook Graph API response.
"data": [
{
"actions": [
{
"action_type": "comment",
"value": "2"
},
{
"action_type": "offsite_conversion",
"value": "1606"
}
],
"date_start": "2017-04-03",
"date_stop": "2017-05-02"
},
{
"actions": [
{
"action_type": "post",
"value": "2"
},
{
"action_type": "post_reaction",
"value": "33"
},
{
"action_type": "page_engagement",
"value": "816"
},
{
"action_type": "post_engagement",
"value": "807"
},
{
"action_type": "offsite_conversion",
"value": "1523"
}
],
"date_start": "2017-04-03",
"date_stop": "2017-05-02"
},
]
The Number of values is flexible and i want to get the value from "offsite_conversion". Normally i would do it for example like that:
data['data'][0]['actions']['1']['value']
But in that case this doesn't work because ['1'] is variable.
Use a loop and test the action type.
foreach ($data['data'][0]['actions'] as $action) {
if ($action['action_type'] == 'offsite_conversion') {
$result = $data['value'];
break;
}
}
because "offsite_conversions" is always the last
If $data['data'][0]['actions'][LAST VALUE]['value'] is what you're looking for:
Your idea of counting should work then:
$actions = $data['data'][0]['actions'];
$index = count($actions) - 1;
$value = $actions[$index]['value'];
So not completely clear what are you trying to achieve, but in a simple way you can just iterate over your $data array:
$needed_values = array();
foreach ($data['data'] as $item) {
foreach ($item['actions'] as $action) {
if ($action['action_type'] == 'offsite_conversion') {
$needed_values[] = $action['value'];
}
}
}
Barmar has the best approach if you don't know where it is, but it's much easier if you want the last one:
$result = end($data['data'][0]['actions'])['value'];
Pretend $json holds the data from facebook
<?php
$data = json_decode($json);
$conversions = 0;
foreach ($data as $datum) {
foreach ($datum['actions'] as $action) {
if ($action['action_type'] === 'offsite_convserion') {
$conversions += (int)$action['value'];
break;
}
}
}

How to decode this json with foreach

This is the JSON
{
"circuit_list": [
{
"_id": "58c0f378a986f808cdaf94cf",
"aggregation": {
"dev_name": "ME2-D2-BOO",
"port": {
"desc": "AKSES_SITE_SITE-TSEL_ME2-D2-BOO#1/2/5_200M_BOO082#CIPAKUBOO534",
"name": "1/2/5"
}
},
"area": "AREA 2",
"site_id": "N/A",
"site_name": "N/A"
},
{
"_id": "58c0f378a986f808cdaf94d0",
"aggregation": {
"dev_name": "ME2-D2-BOO",
"port": {
"desc": "AKSES_SITE_SITE-TSEL_ME2-D2-BOO#1/2/5_200M_BOO082#CIPAKUBOO534",
"name": "1/2/5"
}
},
"area": "AREA 2",
"site_id": "N/A",
"site_name": "N/A"
}
}
I already try with this code
$json = json_decode($url, true);
foreach($json as $value)
{
$_id = $value->_id;
}
it didn't work. Please help, I need to get the value to show them on the view. Did I do this wrong? this json is difficult because i didn't understand the structure.
I usually decode json with format
[{"id":"1","name":"faisal"}]
like this and with my foreach it's working.
If the second parameter of json_decode is true, the function will return an array instead of an object. Also, you would need to loop over the circuit_list property of the object.
$json = json_decode($url); // <- remove the parameter
foreach($json->circuit_list as $value) // <- loop over circuit_list
{
$_id = $value->_id;
}
<?php
$json = json_decode($url,true);
foreach($json['circuit_list'] as $value)
{
$id = $value['_id'];
}
?>

Laravel - Format JSON

I have a code that outputs the json result below:
{
"Ghost in the Shell": {
"id": 1203,
"Pipeline": {
"id": 6144,
"name": "Pipeline",
"status": "New",
"item_id": 5962,
"TotalTasksOpen": 2
}
}
}
Now how can I format it in the my desired json format below:
Note* I have to remove some result.
{
"Ghost in the Shell":
"id": 6144,
"name": "Pipeline",
"status": "New",
"item_id": 5962,
"TotalTasksOpen": 2
}
Will appreciate if anyone can help me please.
I am not sure what is your purpose , but here is what you need
<?php
$json = '{
"Ghost in the Shell": {
"id": 1203,
"Pipeline": {
"id": 6144,
"name": "Pipeline",
"status": "New",
"item_id": 5962,
"TotalTasksOpen": 2
}
}
}';
$array = json_decode($json, true);
$newArray = array();
foreach($array as $key=>$value) {
$newArray[$key] = '';
foreach($value as $k=>$v) {
if(is_array($v)) {
$newArray = array_merge($newArray,$v);
}
}
}
$newJson = json_encode($newArray);
echo $newJson;
?>

json, php - output string from array

I am trying to decode JSON data to PHP then output it to the site. If I have the following:
{
"name": "josh",
"type": "human"
{
I can do this (within PHP), to display or output my type:
$file = "path";
$json = json_decode($file);
echo $json["type"]; //human
So, if I have the following:
{
"name": "josh",
"type": "human",
"friends": [
{
"name": "ben",
"type": "robot"
},
{
"name": "tom",
"type": "alien"
}
],
"img": "img/path"
}
How can I output what type my friend ben is?
Use a loop like foreach and do something like the following:
//specify the name of the friend like this:
$name = "ben";
$friends = $json["friends"];
//loop through the array of friends;
foreach($friends as $friend) {
if ($friend["name"] == $name) echo $friend["type"];
}
To get the decoded data in array format you would supply true as the second argument to json_decode otherwise it will use the default which is object notation. You could easily create a function to shorten the process when you need to find a specific user
$data='{
"name": "josh",
"type": "human",
"friends": [
{
"name": "ben",
"type": "robot"
},
{
"name": "tom",
"type": "alien"
}
],
"img": "img/path"
}';
$json=json_decode($data);
$friends=$json->friends;
foreach( $friends as $friend ){
if( $friend->name=='ben' )echo $friend->type;
}
function finduser($obj,$name){
foreach( $obj as $friend ){
if( $friend->name==$name )return $friend->type;
}
}
echo 'Tom is a '.finduser($friends,'tom');
try this,
$friend_name = "ben";
$json=json_decode($data);
$friends=$json->friends;
foreach( $friends as $val){
if($friend_name == $val->name)
{
echo "name = ".$val->name;
echo "type = ".$val->type;
}
}
