I'm getting a json response and have converted into array using json_decode.
var_dump gives the following:
array(1) {
["FlightInfoResult"]=>
array(2) {
["next_offset"]=>
int(1)
["flights"]=>
array(1) {
[0]=>
array(19) {

string(6) "AXB443"

["destinationName"]=>
string(10) "Seeb Int'l"
["destinationCity"]=>
string(6) "Muscat"
}
}
}
}
I need to get the contents that comes within flights, ident:AXB443, etc..
I am not able to print any elements of the array.
This is multidimensional array. After json_decode you can get it via $variable['FlightInfoResult']['flights'][0]['ident'];
An variant on var_dump() is print_r(). This will give a simpeler, but in this case better to understand output.

I just need to parse a JSON :

How to parse all the datas from this JSON with PHP by using object return.
Thanks in advance for help.
Use json_decode.
Returns as object:
json_decode($json_string);
Returns as associative array:
json_decode($json_string, true);
From what I guess you used json_decode and it returned object. You can now access object values using variable name let's say $var
echo $var->type; // will output champion
You can also convert json to array by providing second argument set to true
then you can access this data via
echo $var['type'];
I am trying to pull one single piece of data from a json encoded string. I managed to get the string into php's jason format, but I dont understand how to display the exact data I want (confirmations) Every time I try to access any of the data it just gives me a bracket({) and no data. I know I'm doing something wrong with retreiving the data from the variable, but I can't pu tmy finger on it.
Here's the data I want to parse, could someone please show me how to access the confirmations value from within the array of data? Thanks.

Source Code:
<?PHP
$return = file_get_contents("https://api.chain.com/v2/bitcoin/transactions/76e6f17cb940745255e2b8439eea5dae945a b148f1fbba98a9fb99c9a5801320?api-key-id=ae7317a1cd4ff0d12e49a77bfd8b9dec");
var_dump(json_decode($return));
echo $return[0]["confirmations"]; //one of my many attempts to get the info, also tried without the leading zero, and different numbers. I understand arrays, I just dont understand how the json data is formatted inside the array.
?>
Output Copy(what do I do with $return to get it's confirmation value of 2896?):

Have a look at the docs: http://php.net/json_decode
Convert the json-string to a php-array and save it in a variable. Then use it like any other array to get values from it. Like this:
$return = file_get_contents('http://etc.com/');
$decoded_return = json_decode($return);
echo $decoded_return['confirmations']; //Make sure the key exists, obviously
So keep in mind that $return is a string. The json_decode function returns an array, so you have to save that array in a (new - preferably) variable to get values from it.
I am trying to decode JSON
I am reading the JSON through STOMP. There are different JSON datasets so I need to work out which JSON dataset has come through. I do this by reading its title.
However there is one particular dataset I am having trouble reading
foreach (json_decode($msg->body,true) as $event) {
if(isset($event['schemaLocation'])) {
$schedule_id=($event['schedule']['schedule_start_date']);
$signalling_id=($event['schedule']['schedule_segment']['signalling_id']);
echo $schedule_id;
}
In the above example the isset function works fine and also $schedule_id obtains the right answer
However the $signalling_id gives an error of Undefined index:
Here is a dump of PART of the JSON (Its rather long............).The piece of JSON with the signalling_id is towards the end of the JSON. Any help to get the variable signalling_id much appreciated.

schedule_segment is itself an array, so instead of
['schedule']['schedule_segment']['signalling_id']);
that should probably be
['schedule']['schedule_segment'][0]['signalling_id']);
As you can see in the var dump, signalling_id is inside another array. Use:
$signalling_id=($event ['schedule']['schedule_segment'][0]['signalling_id']);
If that one element array with key 0 is not constant throughout, you may need some logic to figure out what it is in each iteration.
How to get the last array value of this var_dump?
I do a var_dump on a variable ($submission) and get this:
object(stdClass)#148 (8) {
["sid"]=> string(3) "199"
["nid"]=> string(4) "3042"
["submitted"]=> string(10) "1386113448"
["remote_addr"]=> string(9) "127.0.0.1"
["uid"]=> string(2) "21"
["name"]=> string(8) "SClosson"
["is_draft"]=> string(1) "0"
["data"]=> array(1) {
[1]=> array(1) {
[0]=> string(8) "blahblah"
}
}
}
So I need to store blahblah in a variable from the above array, but how?
Thought I could just get it by doing this: $submission['data'][1][0], but that doesn't work. How do I return blahblah from this?
If you need an array, you can type cast it
$result = (array) $submission;
Or as an object, access the data as public properties
echo $submission->data[1][0];
You can use array_pop if you want to get the last value of an array.

Okay, so I'm writing an app that allows me to see steam data from a database of whoever registered.
I met a problem. Firstly, the steam API for multiple users is not standardized. (e.g. everytime you refresh this, the position of user changes (What kind of API does this?!)
Since steam does not standardize the API, I'll have to do it myself, so after doing a json_decode($url, true). It is not an assoc array.
I want to sort the assoc array by the steam ID (which is numeral) and match them against my own database of user (also contains steam ID, but can be sorted in the database), so how do I go about doing that?
E.g.
Array 1:
array(3) {

array(2) {

For sortig array you can find a list of all function that you need here
Update:
first you must create a 1d array from a 2d or 3d you can use this code to make an easy access array and sortable (this an example):
<?php
$inArr;//This is the 2D array
$outArr = array();
for($i=0;$i<count($inArr);$i++){
$outArr[$i] = $inArr[$i][0];
?>
then you can sort it with ksort() or krsort() function.and for adding an array to another :
<?php
$stack = array("value1", "value2");
array_push($stack, "value3", "value4");
print_r($stack);
?>
