Empty Response Web Service Doctrine 2 Slim 3 - php

There is happening something really freaky, The following code is from a request I have in my Web Service using Slim 3 and Doctrine 2, I am geetting a empty response, I know for a fact the array it's getting filled but it is returning empty!
$data = $request->getParsedBody();
$intervention_items = $this->em->getRepository('App\Entity\V_Interventionitems')
->findAll(array('ic_interventiontype_id' => $data['it_id']));
foreach ($intervention_items as $int_items){
$data_response[] = $int_items->toArray();
//echo json_encode($int_items->toArray()); here prints the info right
}
return $response->withStatus(200)
->withHeader('Content-Type', 'application/json')
->write(json_encode($data_response)); //here returns empty
I know this issue is very amateur but I am invoking the Knoledge of my friends to help me out ;)


json_encode($data_response) is returning false. Use json_last_error() to find out what is wrong.

php - Detect bad request

I have 2 JSON sources and one of them reply 400 Bad request (depend of charge in servers)
So I want that my php code check the answer of both server and select working one
<?php
$server1 = 'server1.lan'
$server2 = 'server2.lan'
/*
Here a code to check and select the working server
*/
$json=file_get_contents('https://'.$workingServer.'/v1/data?source='.$_GET['source']);
$data = json_decode($json);
if (count($data->data)) {
// Cycle through the array
foreach ($data->data as $idx => $data) {
echo "<p>$data->name</p>\n";
?>
Thanks !

Below is an idea of what you may want to implement. Your goal is to get that idea and implement something like that in your own way, with a normal error handling and removal of code duplication:
$json = file_get_contents('https://server1.lan/v1/data');
if ($json === false)
{
$json = file_get_contents('https://server2.lan/v1/data');
if ($json === false)
{
die('Both servers are unavailable');
}
}
file_get_contents returns boolean false on failure, so if the first server is unavailable, call the second. If it is also unavailable, exit the script, or do some sort of error handling that you prefer.
You may want to create an array of possible server names, and use a function that iterates over all of them until it finds a working one, and returns the contents, or throws an exception on failure.
I would also suggest that you use curl, which gives you an option to see the error codes of the request, customize the request itself, and so on.

Check $http_response_header after making the file_get_contents call.
$json = file_get_contents(('https://'.$server1.'/v1/data?source='.$_GET['source']);
if (strpos($http_response_header[0],"400") > 0)
{
$json = file_get_contents(('https://'.$server.'/v1/data?source='.$_GET['source']);
}
See examples at http://php.net/manual/en/reserved.variables.httpresponseheader.php

Check if update push is succesfull

I update an existing document with the code below. Its working fine.
foreach($jArray as $value){
!!some code!!
try {
$collection->update(array("tablename"=>$tablename),array('$push' => array("inventar" => $new_data)));
echo json_encode($collection);
}
catch ( MongoConnectionException $e ) {
echo '<p>Update failed</p>';
exit();
}
}
JSON response:
{"w":1,"wtimeout":10000}{"w":1,"wtimeout":10000}
(2 values are tried to update)
Even if no tablename matched, means no update happend, the result is w = 1.
Why? No update happend and w is 1/true?

There seems to be a little confusion here. The JSON response you are looking at is not the actual return value from the update operation. What you did was JSONifying the collection itself, which has the integer attributes w and wtimeout (see source code here). Those attributes are in no way related to the result of the update operation itself.
So, the right way to go seems to be changing the lines inside the scope of your try statement to:
$result = $collection->update(array("tablename"=>$tablename),array('$push' => array("inventar" => $new_data)));
echo json_encode($result);
For more information about what is returned from the update method, refer to these docs.

Getting Guzzle Twitter response data

Hopefully the solution to this is a lot more simple than what I've been trying!
I've got a Symfony 2.3 app where I'm attempting to get the number of followers of a Twitter users account. I get back data but I can't access it by array key/index values.
Controller Action:
public function twitterAction(){
$twitterClient = $this->container->get('guzzle.twitter.client');
$response = $twitterClient->get('1.1/followers/ids.json?screen_name=ACCOUNTNAME')
->send()->json();
return $this->render('CatablogSiteBundle:Default:status.html.php', array('response' => $response));
}
View:
<?php
var_dump($response);
echo '<br><br>';
echo gettype($response);
echo '<br><br>';
echo $response[0];
?>
I get back data that I want to use from var_dump, gettype responds with type Array , and attempting to reference $response[0] will fail completely.
What can I do to access data inside the response Object?
edit:
Of course I can't echo $response[0] ... (wrong type) don't try and code tired guys. Solved whilst going over NHG's answer, which is still helpful for anyone having problems with Guzzle.

If I understood TwitterClient extends Guzzle\Service\Client (based on https://github.com/RobinvdVleuten/guzzle-clients/blob/master/Twitter/TwitterClient.php, isn't it?). So, let's try this one:
echo $response->getBody();
// for getting body
echo $response->getHeader('Content-Length');
// for getting Content-Length body
$data = $response->json();
// for getting response in json format

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);

Instagram Real time API - PHP - Unable to get POST Update

I'm trying to connect with the instagram API, the connection works fine and I am receiving the updates just as described in the API documentation, the issue is that I cannot access to the data send to my callback function.
According to the doc
When someone posts a new photo and it triggers an update of one of your subscriptions, we make a POST request to the callback URL that you defined in the subscription
This is my code :
// check if we have a security challenge
if (isset ($_GET['hub_challenge']))
echo $_GET['hub_challenge'];
else // This is an update
{
// read the content of $_POST
$myString = file_get_contents('php://input');
$answer = json_decode($myString);
// This is not working starting from here
$id = $answer->{'object_id'};
$api = 'https://api.instagram.com/v1/locations/'.$id.'/media/recent?client_secret='.INSTA_CLI_SECRET.'&client_id='.INSTA_CLI_ID;
$response = get_curl($api); //change request path to pull different photos
$images = array();
if($response){
$decode = json_decode($response);
foreach($decode->{'data'} as $item){
// do something with the data here
}
}
}
Displaying the $myString variable I have this result, don't know why it is not decoded to json :(
[{"changed_aspect": "media", "subscription_id": 2468174, "object":
"geography", "object_id": "1518250", "time": 1350044500}]
the get_curl function is working fine when I hardcode my $id.
I guess something is wrong with my $myString, unfortunately the $_POST cvariable is not populated, Any idea what I am missing ?

Looking at the example JSON response included in your question, I can conclude that the object you are trying to talk with is wrapped in an array (hence the [ and ] around it in the JSON string).
You should access it using $answers[0]->object_id.
If that doesn't work, you can always use var_dump to check out the data in one of your variables.
