I am trying to parse a xml to a nested json structure with php.
This is my test script:
$json_drives = array();
foreach($drives->DR as $dr){
$current_drive = array();
$current_drive['id'] = $dr->ID;
$current_drive['name'] = $dr->NAME->D;
$json_drives[] = $current_drive;
}
echo("Finished");
// Parse and save
$f = json_encode($json_drives);
file_put_contents('test12345.json', $f);
I get a structure like that:
[
{
"id": {
"0": "1"
},
"name": {
"0": "Name 1"
}
},
{
"id": {
"0": "2"
},
"name": {
"0": "Name 2"
}
},
// ...
]
But I dont want the keys "id" and "name" to be nested. It should look like this:
[
{
"id": "1"
"name": "Name 1"
},
{
"id": "2"
"name": "Name 2"
},
// ...
]
How can I handle that?
Assuming your JSON's "drive" objects will always have this structure:
"id": {
"0": "Some ID"
},
"name": {
"0": "Some name"
}
You can use:
$current_drive['id'] = ((array) $dr->ID)[0];
$current_drive['name'] = ((array) $dr->NAME->D)[0];

I'm trying to parse data returned by the Jotform API.
I'm successfully echoing the data but I'm also getting unnecessary additional lines of text.
My PHP code is:
include "JotForm.php";
$jotformAPI = new JotForm("myapikey");
$submissions = $jotformAPI->getFormSubmissions("myformid");
var_dump($submissions );
foreach ($submissions as $data) {
$detail = $jotformAPI->getSubmission($data['id']);
foreach ($detail as $d) {
echo $d[1]['answer']['first'] . '<br>';
}
}
result of var_dump($submissions );
{
"responseCode": 200,
"message": "success",
"content": [{
"id": "237955080346633702",
"form_id": "31751954731962",
"ip": "123.123.123.123",
"created_at": "2013-06-25 03:38:00",
"updated_at": "2013-06-27 04:58:00",
"status": "ACTIVE",
"new": "1",
"answers": {
"1": {
"text": "Name",
"type":"control_fullname",
"answer": {
"first": "LeBron",
"last": "James"
},
"prettyFormat": "LeBron James"
},
"2": {
"text": "Your Message",
"type": "control_textarea",
"answer":"¡Ay, caramba!"
}
}],
}
And here is the result I'm getting:
1
0

I had to repair your invalid json string...
Code: (Demo)
$json = '{
"responseCode": 200,
"message": "success",
"content": [{
"id": "237955080346633702",
"form_id": "31751954731962",
"ip": "123.123.123.123",
"created_at": "2013-06-25 03:38:00",
"updated_at": "2013-06-27 04:58:00",
"status": "ACTIVE",
"new": "1",
"answers": {
"1": {
"text": "Name",
"type":"control_fullname",
"answer": {
"first": "LeBron",
"last": "James"
},
"prettyFormat": "LeBron James"
},
"2": {
"text": "Your Message",
"type": "control_textarea",
"answer":"¡Ay, caramba!"
}
}}]
}';
foreach (json_decode($json, true)['content'] as $set) {
echo "{$set['answers'][1]['answer']['first']} {$set['answers'][1]['answer']['last']}\n";
}
Output:
LeBron James
I'm a little fuzzy on the action of the jot functions, but maybe it's supposed to be like this:
foreach ($submissions as $data) {
$detail = $jotformAPI->getSubmission($data['id']);
echo $detail['answers'][1]['answer']['first'] . '<br>';
}
I'm trying to parse a JSON file which looks like this,
[
{
"id": "539eebdba276db40a4716726",
"name": "Development Task",
"idList": "539eebbb4e9a8d709704b254",
"desc": "",
"url": ""
},
{
"id": "539eebe09b42c971d46b9ba1",
"name": "Design Task",
"idList": "539eebbe50dc4fa2a82474fc",
"desc": "",
"url": ""
}
]
I'm trying to get the desc object from the array with the name Development Task, the system needs to be dynamic so I can't just use json_o[0](desc);
I've tried different methods such as foreaching the data multiple times but I still can't think of a solution, any help would be great, cheers.
Try with this:
$jsonData = '[
{
"id": "539eebdba276db40a4716726",
"name": "Development Task",
"idList": "539eebbb4e9a8d709704b254",
"desc": "",
"url": ""
},
{
"id": "539eebe09b42c971d46b9ba1",
"name": "Design Task",
"idList": "539eebbe50dc4fa2a82474fc",
"desc": "",
"url": ""
}
]';
$encoded = json_decode($jsonData);
foreach($encoded as $data)
{
if('Development Task' == $data->name)
{
echo $data->desc;
}
}
If you search for dynamic fields, i would have gone with :
$jsonData = '[
{
"id": "539eebdba276db40a4716726",
"name": "Development Task",
"idList": "539eebbb4e9a8d709704b254",
"desc": "FirstDescription",
"url": ""
},
{
"id": "539eebe09b42c971d46b9ba1",
"name": "Design Task",
"idList": "539eebbe50dc4fa2a82474fc",
"desc": "SecondDescription",
"url": ""
}
]';
$arrayFromJson = json_decode($jsonData, true);
function searchByKey($keyToSearchIn, $searchName, $array) {
foreach ($array as $key => $val) {
if ($val[$keyToSearchIn] == $searchName) {
return $val['desc'];
}
}
return null;
}
$return = searchByKey("name", "Development Task", $arrayFromJson);
So
var_dump($return);
returns
string(16) "FirstDescription"
Note : If you only need a search by name, you can change the function with :
function searchByName( $searchName, $array) {
foreach ($array as $key => $val) {
if ($val['name'] == $searchName) {
return $val['desc'];
}
}
return null;
}
$return = searchByName("Development Task", $arrayFromJson);
Hope it helps.
The comments in the code explain what happens:
$jsonData = '[
{
"id": "539eebdba276db40a4716726",
"name": "Development Task",
"idList": "539eebbb4e9a8d709704b254",
"desc": "moocow",
"url": ""
},
{
"id": "539eebe09b42c971d46b9ba1",
"name": "Design Task",
"idList": "539eebbe50dc4fa2a82474fc",
"desc": "wowcow",
"url": ""
},
{
"id": "539eebe09rb42c971d46b9ba1",
"name": "Development Task",
"idList": "539eebbe50dc4fa2a82474fc",
"desc": "sowccow",
"url": ""
}
]';
$encoded = json_decode($jsonData, true); //converts the json object to an array
foreach ($encoded as $arrayObject){
if( in_array("Development Task", $arrayObject) ){
print_r($arrayObject['desc'] . "\n");
}
}
-> moocow sowccow
based upon
I'm trying to get the desc object from the array with the name Development Task
This should do what you want and you can easily take the string and make it a variable. There are plenty of built-in functions on PHP.net that are tuned and are probably 10x better than rolling your own code.
This is the JSON response that I'm getting from database. I want to print these data. For now, there's only 2 entries in my table. So the length of JSON should be 2. As data increases, count has to get increase. SO for showing output, I use a for loop. And I used count() for limiting the iteration of loop only once through the JSON.
MY JSON:
{
"log": [
{
"action": "qq",
"id": "1",
"Time": "2014-05-19T15:40:06+05:30",
"user": {
"firstName": "dani",
"type": {
"zzs": "1",
"typename": "lolo",
"id": "1",
"zzt": "1",
"zzu": "1",
"zzv": "1",
"zzw": "1",
"zzx": "1"
},
"id": "1",
"lastName": "fed",
"password": "lmfao",
"userName": "fyi"
},
"userIpAddress": "101.15.23.45"
},
{
"action": "vv",
"id": "2",
"Time": "2014-05-20T10:16:33+05:30",
"user": {
"firstName": "dani",
"type": {
"zzs": "1",
"typename": "lolo",
"id": "1",
"zzt": "1",
"zzu": "1",
"zzv": "1",
"zzw": "1",
"zzx": "1"
},
"id": "1",
"lastName": "web",
"password": "rolf",
"userName": "asap"
},
"userIpAddress": "192.168.0.181"
}
]
}
MY PHP
$out = json_decode($json_data, true);
$x= count($out);
echo $x;
The value that I get is 1 instead of 2. And as you can see I have an associative array. I was trying to print those datas.
for($i=0; $i<$x; $i++)
{
echo $out['action'];
echo $out['user'][$i]['firstName'] ;
echo $out['user']['type'][$i]['typename'] ;
}
I don't get output. HELP???
I think it may be counting just the "Log"... technically that response is 2 dimensional:
data[0] = log
data[0][0] = log.firstRecord
data[0][1] = log.secondRecord
Try iterating through the second dimension
you have 2 element inside log key in your array.
try this:
$x= count($out['log']);
this will count 2
demo
for your loop you should try like this:
$out = json_decode($json_data, true);
$x= count($out['log']);
$out = $out['log'];
for($i=0; $i<$x; $i++)
{
echo $out[$i]['action'];
echo $out[$i]['user']['firstName'] ;
echo $out[$i]['user']['type']['typename'] ;
}

I have web page which get Json responce like this
{
'hotel_1page':[
{
'id':'10',
'name':'fsf',
'telephone':'233333'
},
{
'id':'11',
'name':'setttttt',
'telephone':'213123123'
},
{
'id':'12',
'name':'fsdfsdf',
'telephone':'122212121'
},
{
'id':'13',
'name':'xxcvcxv',
'telephone':'2147483647'
},
{
'id':'14',
'name':'dssdfg',
'telephone':'2147483647'
},
{
'id':'15',
'name':'dfsdfsdf',
'telephone':'21312321'
},
{
'id':'16',
'name':'fx_test_nw1',
'telephone':'23232323'
},
{
'id':'17',
'name':'fx_test_nw2',
'telephone':'31313131'
}
]
}
and i want to loop through this data and get this data to array and display as html how can i achieve this
this is where i get get json responce,and when i var_dump json encoded variable it says null,where $json variable shows the json responce,
$json = file_get_contents('http://www.example.com/hotel_list.php');
var_dump($json);
$array = json_decode($json, true);
var_dump($array);
The json that you are trying to parse is invalid. Change the single quotes to double quotes and you should be able to parse it to an array.
The JSON documentation says
A value can be a string in double quotes, or a number, or true or false or null, or an object or an array. These structures can be nested.
This should work:
$json = '{ "hotel_1page": [ { "id": "10", "name": "fsf", "telephone": "233333" }, { "id": "11", "name": "setttttt", "telephone": "213123123" }, { "id": "12", "name": "fsdfsdf", "telephone": "122212121" }, { "id": "13", "name": "xxcvcxv", "telephone": "2147483647" }, { "id": "14", "name": "dssdfg", "telephone": "2147483647" }, { "id": "15", "name": "dfsdfsdf", "telephone": "21312321" }, { "id": "16", "name": "fx_test_nw1", "telephone": "23232323" }, { "id": "17", "name": "fx_test_nw2", "telephone": "31313131" } ] }';
echo '<pre>';
var_dump(json_decode($json, true));
echo '</pre>';
I replaced all single quotes with double quotes, that did the trick.
I used single quotes before which caused json_decode to return null
[Edit for usage]
To use the data, you could use something like this:
$obj = json_decode($json, true);
foreach($obj as $row)
{
foreach($row as $key => $item)
{
// $item['id']
// $item['name']
// $item['telephone']
}
}
I'm using a nested foreach() because the id, name and telephone are an array within the hotel_page1 array
I'm trying to build a JSON object from a mysql query. The JSON structure that I'm striving for should look like this:
{
"a": [
{
"user": "alb",
"time": "2011-09-12 05:56:36"
},
{
"user": "arg",
"time": "2011-09-12 05:56:36"
}
]
"b": [
{
"user": "blah",
"time": "2011-09-12 05:56:36"
},
{
"user": "bleh",
"time": "2011-09-12 05:56:36"
}
]
}
However, my code always returns a JSON object wrapped in an array like so:
[
{
"a": [
{
"user": "alb",
"time": "2011-09-12 05:56:36"
},
{
"user": "arg",
"time": "2011-09-12 05:56:36"
}
]
"b": [
{
"user": "blah",
"time": "2011-09-12 05:56:36"
},
{
"user": "bleh",
"time": "2011-09-12 05:56:36"
}
]
}
]
Here is the php code I'm using:
<?php
$json_data = array();
foreach($blogs as $blog)
{
$sql = "SELECT * from users";
$query = mysql_query($sql);
$ablog = array();
while ($row = mysql_fetch_assoc($query))
{
$json_element = array(
"user"=> $row[username] ,
"time"=> $row[time]
);
array_push($ablog,$json_element);
}
$eblog = array($blog => $ablog);
array_push($json_data,$eblog);
}
$json_output = json_encode($json_data);
print $json_output;
?>
I was wondering: Why am I getting a JSON object wrapped in an array? What am I doing incorrectly in the code above?
Thank you.
The following two lines are creating one-element associative arrays and appending the one-element array to your larger $json_data array:
$eblog = array($blog => $ablog);
array_push($json_data,$eblog);
Instead, just add a new key/value pair to your original array:
$json_data[$blog] = $ablog;
