How to obtain a value from a multidimensional json array - php

i'm entirely new to this site, so i'm sorry in advance if my post is not formatted properly.
Anyway, i have what i expect to be a fairly simple question. I'm extracting values from a "request body"-array-thingy, and i got most of what i need by using these 4 lines of code:
$payment_id = strval($callback_json->id);
$order_id = strval($callback_json->order_id);
$currency = strval($callback_json->currency);
$card_brand = strval($callback_json->metadata->brand);
My problem now is that i've run out talent when trying to get the "amount" value that seems to be a "sub-variable" to "operations".
I've tried doing it like this, but neither of them work:
$amount_total = strval($callback_json->operations[amount]);
$amount_total = strval($callback_json->operations->amount);
So my question now is; How do i format this line to get the value "69500".
I really hope someone out there can help me! :-)
{
"id":9256797,
"order_id":"23322651466",
"accepted":true,
"type":"Payment",
"text_on_statement":null,
"branding_id":null,
"variables":{},
"currency":"DKK",
"state":"new",
"operations":[{
"id":1,
"type":"authorize",
"amount":69500,
"pending":false,
"qp_status_code":"20000",
"qp_status_msg":"Approved",
"aq_status_code":"20000",
"aq_status_msg":"Approved",
"data":{},
"callback_url":"http://requestb.in/105y8k81",
"callback_success":null,
"callback_response_code":null,
"created_at":"2015-12-05T12:40:40+00:00"
}],
"metadata":{
"type":"card",
"brand":"visa",
"last4":"0008",
"exp_month":11,
"exp_year":2016,
"country":"DNK",
"is_3d_secure":false,
"hash":"6f976a4e388928beb4ad3OrQHCS2LDGNAFZVK3i54p6q8heV0RRci",
"number":null,
"customer_ip":"2.110.77.40",
"customer_country":"DK",
"fraud_suspected":false,
"fraud_remarks":[]
}

use
$amount_total = strval($callback_json->operations[0]->amount);
because [ in json is an open tag for an array.
{'foo':[{'bar':"A"},{'bar':"B"}]}
$val->foo[0]->bar; # A
$val->foo[1]->bar; # B
Hope that helps.

Multiple JSON data

I checked every stack overflow solution for it. On ajax request PHP return JSON data but it has multiple JSON data.
var json = '[{"key":"amazon"},{"key":"a a"},{"key":"a and w"},{"key":"a aa"},{"key":"a and e"},{"key":"a aa movie"},{"key":"a aa songs"},{"key":"a aa telugu movie"},{"key":"a aa full movie"},{"key":"a and f"}][{"key":"a beautiful mind"},{"key":"a boogie"},{"key":"a bigger splash"},{"key":"a bronx tale"},{"key":"a brief history of time"},{"key":"a bola"},{"key":"a bugs life"},{"key":"a bientot"},{"key":"a bathing ape"},{"key":"a beautiful mess"}]';
console.log(JSON.parse(json));
$.each(JSON.parse(json), function(idx, obj) {
console.log(obj.key);
});
in var JSON there are two sets one [] and second [] which is causing problems to iterate. If it has only one set [] then it works fine.
PHP Code:
foreach($str as $key => $keyword){
$finalData[$key]['key'] = $keyword;
}
print_r(json_encode($finalData));
Note: It may return data with more than 100 of [], but in above example I just mention two.
Kindly help me out.
What you are trying to create is invalid JSON.
Please wrap your two [] with another [] and comma between both []. Refer code below.
//Sample Code and data
var json = '[[{"key":"amazon"},{"key1":"amazon1"}],[{"key":"amazon"},{"key1":"amazon1"}]]';
console.log(JSON.parse(json));
If more help needed, I'm happy to help.
Thanx, Happy Coding.

Getting currency conversion data from Yahooapis now that iGoogle is gone

Up until yesterday I had a perfectly working budget organizer site/app working with iGoogle.
Through PHP, using the following little line
file_get_contents('http://www.google.com/ig/calculator?hl=en&q=1usd=?eur');
and similar I was able to get all I needed.
As of today, this is no longer working. When I looked into the issue, what has happened is that Google has retired iGoogle. Bummer!
Anyway, I was looking around elsewhere but I can't find anything that fits my needs. I would REALLY love to just fix it and get it running again by just switching this one line of code (i.e. changing the Google address with the address of some other currency API available) but it seems like none does.
The API from rate-exchange.appspot.com seems like it could be a iGoogle analog but, alas, it never works. I keep getting an "Over Quota" message.
(Here comes an initial question: anybody out there know of a simple, reliable, iGoogle-sort API?)
So I guess the natural thing would be to the Yahoo YQL feature (at least I suppose it is as reliable).
Yahoo's queries look like this:
http://query.yahooapis.com/v1/public/yql?q=select * from yahoo.finance.xchange where pair in ("USDEUR", "USDJPY", "USDBGN")&env=store://datatables.org/alltableswithkeys
What I really can't figure out is how to parse this data. It outputs an XML.
What I used to have is this:
function exchange($inputAmount,$inputCurrency,$outputCurrency) {
$exchange = file_get_contents('http://www.google.com/ig/calculator?hl=en&q='.$inputAmount.$inputCurrency.'=?'.$outputCurrency);
$exchange = explode('"', $exchange);
$exchange = explode('.', $exchange['3']);
$exchange[0] = str_replace(" ", "",preg_replace('/\D/', '', $exchange[0]));
if(isset($exchange[1])){
$exchange[1] = str_replace(" ", "",preg_replace('/\D/', '', $exchange[1]));
$exchange = $exchange[0].".".$exchange[1];
} else{
$exchange = $exchange[0];
}
return $exchange;
}
So the user was able to get the exchange rate from an input currency such as "USD" and an output currency such as "EUR" on a specific amount of money. As I said, this was working swimmingly up until yesterday night.
Any ideas?
Never mind! Solved it!
For anyone interested, here's what I did to get my code to work (with the least chnges possible) with the Yahoo YQL:
// ** GET EXCHANGE INFO FROM YAHOO YQL ** //
$url = 'http://query.yahooapis.com/v1/public/yql?q=select * from yahoo.finance.xchange where pair in ("USDEUR", "EURUSD")&env=store://datatables.org/alltableswithkeys'; //<-- Get the YQL info from Yahoo (here I'm only interested in converting from USD to EUR and vice-versa; you should add all conversion pairs you need).
$xml = simplexml_load_file($url) or die("Exchange feed not loading!"); //<-- Load the XML file into PHP variable.
$exchange = array(); //<-- Build an array to hold the data we need.
for($i=0; $i<2; $i++): //<-- For loop to get data specific to each exchange pair (you should change 2 to the actual amount of pairs you're querying for).
$name = (string)$xml->results->rate[$i]->Name; //<-- Get the name of the pair and turn it into a string (this looks like this: "USD to EUR").
$rate = (string)$xml->results->rate[$i]->Rate; //<-- Do the same for the actual rate resulting from the conversion.
$exchange[$name] = $rate; //<-- Put the data pairs into the array.
endfor; //<-- End for loop. :)
// ** WORK WITH EXCHANGE INFO ** //
$toeur = array( //<-- Create new array specific for conversion to one of the units needed.
'usd' => $exchange['USD to EUR'], //<-- Create an array key for each unit used. In this case, in order to get the conversion of USD to EUR I ask for it from my $exchange array with the pair Name.
'eur' => 1); //<-- The way I coded the app, I found it more practical to also create a conversion for the unit into itself and simply use a 1, which translates into "do not convert"
$tousd = array(
'eur' => $exchange['EUR to USD'],
'usd' => 1);
This is basically all you need to get all the exchange info you want. After that, you use it all something like this:
amount*$toxxx['coin'];
So, say I wanted to know how many Euro is 100 USD right now:
100*$toeur['usd'];
Piece of cake!
Still a very useful solution by QuestionerNo27. Since early 2015, however, Yahoo YQL apparently slightly changed the XML output of their api. 'Name' now no longer translates into a string like 'USD to EUR', but to 'USD/EUR' and should in the code above be referenced this way:
$toeur = array(
'usd' => $exchange['USD/EUR']
instead of
$toeur = array(
'usd' => $exchange['USD to EUR']
and in a similar fashion for other currency conversions.
I created a routine to convert the currency based on #QuestionerNo27 http://jamhubsoftware.com/geoip/currencyconvertor.php?fromcur=USD&tocur=EUR&amount=1 you can consume this
<?php
$fromcur = $_GET['fromcur'];
$tocur = $_GET['tocur'];
$amt = $_GET['amount'];
// ** GET EXCHANGE INFO FROM YAHOO YQL ** //
$url = 'http://query.yahooapis.com/v1/public/yql?q=select * from yahoo.finance.xchange where pair in ("'.$fromcur.$tocur.'")&env=store://datatables.org/alltableswithkeys'; //<-- Get the YQL info from Yahoo (here I'm only interested in converting from USD to EUR and vice-versa; you should add all conversion pairs you need).
$xml = simplexml_load_file($url) or die("Exchange feed not loading!"); //<-- Load the XML file into PHP variable.
$exchange = array(); //<-- Build an array to hold the data we need.
for($i=0; $i<2; $i++): //<-- For loop to get data specific to each exchange pair (you should change 2 to the actual amount of pairs you're querying for).
$name = (string)$xml->results->rate[$i]->Name; //<-- Get the name of the pair and turn it into a string (this looks like this: "USD to EUR").
$rate = (string)$xml->results->rate[$i]->Rate; //<-- Do the same for the actual rate resulting from the conversion.
$exchange[$name] = $rate; //<-- Put the data pairs into the array.
endfor; //<-- End for loop. :)
// ** WORK WITH EXCHANGE INFO ** //
$conv = $fromcur . '/' . $tocur;
$toeur = array( //<-- Create new array specific for conversion to one of the units needed.
$tocur => $amt*$exchange[$conv], //<-- Create an array key for each unit used. In this case, in order to get the conversion of USD to EUR I ask for it from my $exchange array with the pair Name.
$fromcur => $amt,
"ex_amt" =>$amt*$exchange[$conv]); //<-- The way I coded the app, I found it more practical to also create a conversion for the unit into itself and simply use a 1, which translates into "do not convert"
echo json_encode($toeur);
?>

PHP JSON Google Definitions - accessing a value

EDIT#4: json_decode is failing and returning null on a seemingly valid json string. See below for more info
I am new to JSON/JSONP and I'm running into constant trouble accessing the values in the returned JSON with PHP. I have stripped the JSONP callback without issue using code I found on this board. I am getting a JSONP result from http://www.google.com/dictionary/json?callback=a&sl=en&tl=en&q=love and struggling to access the first result for the meaning. It's a quite complex result, and I need to access the first meaning (in the node "text") from the below JSON result.
http://pastebin.com/hBTeBTUL
My best attempt was:
if (isset($json->primaries[1]->entries[1]->terms[1]->text))
The above was the best I could do, I just keep getting errors trying to return that text node saying it is undefined. I'd prefer to work with objects rather than associative arrays too, if possible, so please avoid telling me to set it to return assoc array.
Any help would be greatly appreciated. I'm really stuck :P
EDIT:
$json->primaries[1]->entries[1]->terms[0]->text didn't seem to work either. Here is the complete script. Ignore the $params array as it is not used, was going to use it to generate the query.
The script has been edited since when I first posted, I had an invalid JSON object, but the error seems to be fixed as it will now parse through JSON formatters.
The error i'm getting trying to print the value out is
PHP Notice: Trying to get property of non-object in /home/outil2/Plugins/GDefine.php on line 23
EDIT#2: added json_decode which was in my original solution, but got lost in the second version
<?php
class GDefine extends Plugin {
public static $enabled = TRUE;
public function onReceivedData($data) {
if ($data["message"][0] == ".def") {
$params = array (
"callback" => "a",
"sl" => "en",
"tl" => "en",
"q" => $data["message"][1]
);
$jsonp = file_get_contents(
"http://www.google.com/dictionary/json?callback=a&sl=en&tl=en&q=" . $data["message"][1]);
$json = json_decode(substr($jsonp, 2, strlen($jsonp)-12));
var_dump($json);
print_r($json->primaries[1]->entries[1]->terms[0]->text);
if (isset($json->primaries[1]->entries[1]->terms[0]->text)) {
$text = $this->bold("Google Definition: ");
$text .= $this->teal($json->primaries[1]->entries[1]->terms[0]->text);
$this->privmsg($data["target"], $text);
} else {
$this->privmsg($data["target"], "error error error");
}
}
}
}
EDIT #3: this is the string I'm trying to json_decode, after using substr to remove the callback function, but am getting a NULL value returned on var_dump($json)

I json_decode that and it returns NULL :(
You're trying to access an object that doesn't exist. Your code:
if (isset($json->primaries[1]->entries[1]->terms[1]->text)) // Doesn't exist
There's no terms[1] in entries[1] in primaries[1]. There's just 1 item; terms[0]. I think this will work for example:
if (isset($json->primaries[1]->entries[1]->terms[0]->text))
The first item in the array is indexed by 0 not 1, maybe that's your mistake.
Edit:
You also need to decode the JSON, change:
$json = substr($jsonp, 2, strlen($jsonp)-12);
to:
$json = json_decode(substr($jsonp, 2, strlen($jsonp)-12));
Edit:
You need to escape some unescaped characters in the JSON as well. Add this to your code:
Change:
$json = json_decode(substr($jsonp, 2, strlen($jsonp)-12));
to:
$json = substr($jsonp, 2, strlen($jsonp) - 12);
$json = str_replace("\\", "\\\\", $json);
$json = json_decode($json);

Fullcalendar.js allDay parameter returned from MySql using Codeigniter

I'm trying to get FullCalendar working on my Codeigniter app, but coming across a problem with the events showing as all day from my JSON feed.
I've found that setting "allDay":false fixes the problem (tested with a static json file) but when i store that value in a mysql DB, then return the data and run the JSON encode, it converts the False into a string, which cause the event to show as all day!
Does anybody know how i can store true or false in my DB (i'm currently storing as text) and return it to my json feed without it being a string? I've tried casting and converting but can't get anything to work!
Examples of my model/controller/json feed below;
Thanks in advance;
Model function
function show_installs()
{
return $this->db->query(
"SELECT id, client_name as title, start, end, concat('/planner/view_install/',id) as url
FROM installs WHERE completed != 2"
)->result();
}
Controller function
function json_installs()
{
$this->load->model('installs_model');
$data = array();
if($query = $this->installs_model->show_installs())
{
$data = $query;
}
$json = json_encode($data);
echo $json;
}
JSON Feed (That doesnt work because of the " around false)
[
{
"id":"18",
"title":"John",
"allDay":"false",
"start":1339585200,
"end":1339592400,
"url":"\/planner\/view_install\/18"
},
{
"id":"19",
"title":"Mike",
"allDay":"false",
"start":"1339585200",
"end":"1339592400",
"url":"\/planner\/view_install\/19"
}
]
Any help would be really appreciated - i just need to get those bloomin quote marks off from false/true and it would work perfectly!
Thanks
Why don't you change the column type in your DB to be boolean instead of text? You could also parse your $json object to convert all booleans_as_text to booleans before you set it in the calendar - quick googling found me this:
for(var i=0; i<$json.length; i++)
$json[i]=/^true$/i.test($json[i]);
You could also set the allDayDefault to false to avoid set allday: false in each event.

Extract Data from a Website using PHP

I am trying to get PHP to extract the TOKEN (the uppercase one), USERID (uppercase), and the USER NAME (uppercase) from a web page with the following text.
{
"rsp":{
"stat":"ok",
"auth":{
"token":"**TOKEN**",
"perms":"read",
"user":{
"id":"**USERID**",
"username":"**USER NAME**",
"fullname":"**NAME OF USER**"
}
}
}
}
(This is from the RTM api, getting the authentication token of the user).
How would I go about doing this? Thanks!
EDIT:
how would i get task name "Buy Milk!" & the due date of the task"2011-02-28T.." using json_decode and php here? Thanks!
{
"rsp":{
"stat":"ok",
"tasks":{
"rev":"REV_NUMBER",
"list":{
"id":"ID_NUMBER",
"taskse­­ries":{
"id":"ID_NUMBER",

}
}
}
}
As Delan suggested, use json_decode. Here is an example of how you would use json_decode to extract the information you require.
// your json string
$string = '{"rsp":{"stat":"ok","auth":{"token":"**TOKEN**","perms":"read","user":{"id":"**USERID**","username":"**USER NAME**","fullname":"**NAME OF USER**"}}}}';
// parse json string to an array
$array = json_decode($string, true);
// auth token
echo $array['rsp']['auth']['token'];
// user details
echo $array['rsp']['auth']['user']['id'];
echo $array['rsp']['auth']['user']['username'];
echo $array['rsp']['auth']['user']['fullname'];
UPDATE I've updated the code to use json_decode's $assoc parameter to convert from an object to an assoc array.
ANOTHER UPDATE To answer your updated question..
how would i get task name "Buy Milk!" & the due date of the task"2011-02-28T.." using json_decode and php here? Thanks!
This code would work to get the values that you want.
//string(9) "Buy Milk!"
echo $array['rsp']['tasks']['list']['taskseries']['name'];
// string(20) "2011-02-28T05:00:00Z"
echo $array['rsp']['tasks']['list']['taskseries']['task']['due'];
This code isn't ideal, but it gets the job done for you.
If the string is JSON, json_decode in PHP will do the trick. It's was implemented in PHP 5.2.0.
