json_decode: can't get foreach to work - php
I'm losing my sight on this.. I can't find a solution and I keep ranting :P
I'm using the Movie Database to get a JSON with some info about a movie. Here's my code:
<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://api.themoviedb.org/3/movie/tt1327773/images?api_key=MY_API_KEY");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_HEADER, FALSE);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
"Accept: application/json"
));
$response = curl_exec($ch);
curl_close($ch);
$posters = json_decode($response, true);
foreach ($posters as $poster) {
$locandina = $poster[0]->posters->file_path;
echo $locandina;
}
?>
Of course print_r($response); works and it prints the array. What doesn't work is the foreach.. I can't get the file_path values. I keep getting Trying to get property of non-object even though I added a , true in the json_decode arguments! Here's the array:
[id] => 132363
[backdrops] => Array (
[0] => stdClass Object (
[aspect_ratio] => 1.78
[file_path] => /zZggWJSG18wPIOrZOgV5LI12LMi.jpg
[height] => 1080
[iso_639_1] =>
[vote_average] => 5.3846153846154
[vote_count] => 2
[width] => 1920
)
[1] => stdClass Object (
[aspect_ratio] => 1.78
[file_path] => /wYuFRYTfx5rVjyhqdf8MXdQzKAo.jpg
[height] => 1080
[iso_639_1] =>
[vote_average] => 5.3479853479854
[vote_count] => 2
[width] => 1920
)
...
)
to have access to file_path you need this array access key: $array["backdrops"][0]["file_path"] -> because it is contained in the first position of an non-associative array as the value of "backdrops"... check it out (;

Getting an XML file in a .asp URL
I need to grab XML data from an .asp URL and cannot figure out where it goes wrong. Tried:
<?php
$url = "http://bookings.emperordivers.com/webScheduleSpecificXML_all.asp";
$feed = file_get_contents($url);
$xml = simplexml_load_string($feed);
// Display the first post title
echo $xml->Schedules->Schedule[0]->Boat;
I hoped this would work, but suspected that the .asp URL is blocking somehow so alternatively tried:
function get_data($url) {
$ch = curl_init();
$timeout = 5;
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
$returned_content = get_data('http://bookings.emperordivers.com/webScheduleSpecificXML_all.asp');
$xml = simplexml_load_string($returned_content);
// Display the first post title
echo $xml->Schedules->Schedule[0]->Boat;
In both case a beautiful white screen. Is there a simple trick to get this working?
Your not accessing it correctly: echo $xml->Schedule[0]->Boat; The format is: SimpleXMLElement Object ( [Schedule] => Array ( [0] => SimpleXMLElement Object ( [Start] => 2017-09-24 [Duration] => 7 [Boat] => MV Emperor Orion [Itinerary] => Best of Maldives [Dep-Arr] => Male [Spaces] => 4 [Rates] => SimpleXMLElement Object ( [Rate] => Array ( [0] => 1149 [1] => 1,057.08 [2] => 1,367.31 ) ) ) ...
How to get json decode array value using PHP
I need one help.I need to get the json decode value inside foreach loop using PHP. I am explaining my code below. $user_qry = "http://oditek.in/takeme/webservice/user2/user_ride_list_v2.php"; $pstflds="mobile=".$mobile; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $user_qry); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, $pstflds); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); $response=curl_exec ($ch); $data=json_decode($response,true); $bikeArr=$data->data; print_r($bikeArr);exit; Its giving the output like below. Array ( [0] => stdClass Object ( [book_id] => 161117193881 [booking_status] => 4 [book_date] => 17-11-2016 [book_time] => 07:38 PM ) [1] => stdClass Object ( [book_id] => 161116183564 [booking_status] => 4 [book_date] => 16-11-2016 [book_time] => 06:35 PM ) ) I need to iterate the above array in foreach loop and get the data.Please help me.
json_decode parameter 2 is assoc When TRUE, returned objects will be converted into associative arrays. default is false reference http://php.net/manual/en/function.json-decode.php json_decode($response, true);
try $data=json_decode($response,true); and youll get assoc array instead of object
Can you try this and see if you get any errors?
foreach($bokeArr as $bike){
echo 'book id = ' . $bike->book_id;
}
Searching in json array for parameter and show correct information
Is it possible to search inside json array which I pull with curl and if match to show only that data?
The array looks like
Array
(
[status] => success
[data] => Array
(
[out] => Array
(
[0] => Array
(
[address] => test address
[amount] => 11
[type] => 1
)
[1] => Array
(
[address] => test address 1
[is_nonstandard] =>
[amount] => 12
[type] => 1
)
)
)
[code] => 200
[message] =>
)
And this is how I pull the array
function get_curl_content_tx($url) {
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HEADER, false);
$result = curl_exec($curl);
curl_close($curl);
return $result;
}
$url=get_curl_content_tx("http://example.com");
$total =json_decode($url,true);
So since there can be more that 1 arrays in [out] => Array as current situation they are two I want to search and match by [address] and when match to give data.
Here is a way to do it :
foreach($arr['data']['out'] as $d){
if(strpos($d['address'], 'testaddress') !== false){
//do something
var_dump($d);
}
}
You need to replace var_dump by whatever you want to do.
I used strpos for the sake of this example, but you might want to use a custom method that would suits your needs better
Hope this helps.
<?php
$outArray = $total['data']['out'];
foreach($outArray as $item) {
// echo $item['address'];
}
?>
Try this:
if(isset($total['data']['out'])){
foreach($total['data']['out'] as $out){
if(isset($out['address'])){
if($out['address'] == "your adress"){
//Your Stuff;
}
}
}
}
How to get data from an array inside json data php
I have the following array of json data. When I try to loop using a for each, php gives me the error "Object of class stdClass could not be converted to string". I want to access the nameserver in the authns array, and the soa array. How do I go about doing that?
stdClass Object (
[error] =>
[domain] => whoisdoma.net
[ip_address] => 108.162.199.120
[authns] => stdClass Object (
[nameserver] => uma.ns.cloudflare.com
[ip] => 173.245.58.146
[location] => San Francisco
)
[soa] => stdClass Object (
[nameserver] => tom.ns.cloudflare.com
[email] => dns.cloudflare.com
[serial] => 2015505396
[refresh] => 10000
[retry] => 2400
[expiry] => 604800
[minimum] => 3600
)
)
This is the code I'm using to get the data:
<?php
$domain = $_GET['domain'];
//set the url
$url = "http://api.site.ga/v1/dns/lookup?domain=".$domain;
//start a curl session
$ch = curl_init();
$timeout = 5;
//set curl options
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
//get the data
$data = curl_exec($ch);
//decode the data
$jsonData = json_decode($data);
//close the curl session
curl_close($ch);
?>
This is the for each loop I'm using
<?php
foreach($jsonData->authns as $authns)
{
echo $authns->nameserver;
}
?>
You need to decode the json object using an associative array.
Here is an exmaple:
$data = json_decode(file_get_contents('http://api.domain.com/call'), true);
$data is now an associative array.
You are looping through authns while it is an object by itself. So your nameserver which you want is actually $authns in its first iteration.
Just access it like $jsonData->authns->nameserver
try this for yourself
foreach($jsonData->authns as $authns)
{
echo $authns;
}
Post multidimensional array using CURL and get the result on server
I am sending data from my local machine to server using CURL. And the data is multidimensional array. Array ( [0] => stdClass Object ( [id] => 1 ) [1] => stdClass Object ( [id] => 0 ) [2] => stdClass Object ( [id] => 11 ) ) I am using this below code for sending the data. $ch = curl_init(); curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch, CURLOPT_VERBOSE, 0); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_URL, "my_url"); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, $array); // $array is my above data But at server when I try to put this incoming data to file or just print_r it gives me this below output Array ( [0] => Array [1] => Array [2] => Array ) But I want the output in multidimensional. I tried with print_r($_POST[0]) but it gives only Array text.
cURL can only accept a simple key-value paired array where the values are strings, it can't take an array like yours which is an array of objects. However it does accept a ready made string of POST data, so you can build the string yourself and pass that instead: $str = http_build_query($array); ... curl_setopt($ch, CURLOPT_POSTFIELDS, $str); A print_r($_POST) on the receiving end will show: Array ( [0] => Array ( [id] => 1 ) [1] => Array ( [id] => 0 ) [2] => Array ( [id] => 11 ) )
I would give a go to serialize and unserialize: 1) Before sending your array, serialize it (and set your transfer mode to binary): (...) curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_BINARYTRANSFER, TRUE); // need this to post serialized data curl_setopt($ch, CURLOPT_POSTFIELDS, serialize($array)); // $array is my above data 2) When you receive the data, unserialize it: $array = unserialize($_POST); More details here and here
$param['sub_array'] = json_encode($sub_array); and on the other side $sub_array= json_decode($_POST['sub_array']);
