I am trying to print the first tweet in the user timeline.
$hometimeline = $twitterObj->get_statusesHome_timeline();
$stream=$hometimeline->responseText;
$user=$stream[0]->user;
$tweet=$user->text;
echo $tweet;
This just won't print anything. What am I doing wrong here?
If I echo $hometimeline->responseText it shows on the screen
[
{"in_reply_to_status_id_str":null, "coordinates":null, "geo":null, "user":{"profile_use_background_image":true,"text":"I am back",....},"id_str":"121212"},
{ ... so on}
]
you are getting a json string as response. Use json_decode to parse the response and you will be able to manage it as array o stdobject
do this just before interact with the response
$stream = json_decode( $hometimeline->responseText, true);
Edit
remember you can always use print_r to debug
Try this instead:
$hometimeline = $twitterObj->get_statusesHome_timeline();
$stream = json_decode( $hometimeline->responseText );
$user=$stream[0]->user;
$tweet=$user->text;
echo $tweet;
json_decode turns the JSON string that you are receiving into a PHP object.

Output when success
string(66)
"{"status":true,"message":"success","data":{"amountDue":"-504.20"}}"
Output when error
string(119) "{"status":false,"message":"An error occured while getting
full subscriber profile: Subscription not found MPP servers"}"
How should I write in php to get the amount due from the output? I am new to REST api. Can someone show me ? Thank you
That is a JSON-encoded response. Use json_decode() to convert the string back into an array, and then access the array element:
$output = '{"status":true,"message":"success","data":{"amountDue":"-504.20"}}';
$results = json_decode($output,true);
if($results["status"])
{
echo "Success! Data: " . print_r($results,true);
}
I assume that you can at least send proper request to the endpoint and you are able to capture the response.
You receive a json string which must be parses so if:
$response = '{"status":true,"message":"success","data":{"amountDue":"-504.20"}}';
$responseArray = json_decode($response, true);
Then you will get a responseArray as associated array (the second parameter) so you can get amount due like that
$amountDue = $responseArray['data']['amountDue'];
You could also parse json data into an StdClass which turn all fields in json into an object's property. To do that abandon the second parameter in json_decode function
$resultObj = json_decode($response);
$amountDue = $resultObj->data['amountDue'];
All depends on your requests.

I am trying to send json response as :
{"id":13,"user_id":4,"play_list_name":"My Play List12","section":1,"created":"2017-04-14T05:46:47+00:00","status":1}
but the webservice is generating json as:
[{"id":13,"user_id":4,"play_list_name":"My Play List12","section":1,"created":"2017-04-14T05:46:47+00:00","status":1}]
Below is my web service:
$response_data=$this->MyPlaylists->findById($id)->toArray();
echo json_encode($response_data); die;
However below json_encode is generating valide response:
$response_data=array('response'=>0,'message'=>'This is already added in db');
echo json_encode($response_data); die;
Output:
{"response":"already added","message":"This is already added in db"}
toArray() will convert your Object in Array. So you don't need to add toArray() in your result.
$response_data=$this->MyPlaylists->findById($id);// without toArray()
echo json_encode($response_data); die;
Hope above will work and if not, then try the below code,
$response_data=$this->MyPlaylists->findById($id)->toArray();
echo json_encode(
isset($response_data[0]->id)?
$response_data[0]:
array('response'=>0,'message'=>'This is already added in db')
);die;
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

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 $answers[0]->object_id.
If that doesn't work, you can always use var_dump to check out the data in one of your variables.
I am trying to get PHP to extract the TOKEN (the uppercase one), USERID (uppercase), and the USER NAME (uppercase) from a web page with the following text.
{
"rsp":{
"stat":"ok",
"auth":{
"token":"**TOKEN**",
"perms":"read",
"user":{
"id":"**USERID**",
"username":"**USER NAME**",
"fullname":"**NAME OF USER**"
}
}
}
}
(This is from the RTM api, getting the authentication token of the user).
How would I go about doing this? Thanks!
EDIT:
how would i get task name "Buy Milk!" & the due date of the task"2011-02-28T.." using json_decode and php here? Thanks!
{
"rsp":{
"stat":"ok",
"tasks":{
"rev":"REV_NUMBER",
"list":{
"id":"ID_NUMBER",
"taskseries":{
"id":"ID_NUMBER",
"created":"2010-11-16T00:01:50Z",
"modified":"2011-02-28T05:09:36Z",
"name":"Buy Milk!",
"source":"js",
"url":"",
"location_id":"",
"rrule":{
"every":"1",
"$t":"FREQ=WEEKLY;INTERVAL=1"
},
"tags":[
],
"participants":[
],
"notes":[
],
"task":{
"id":"ID_NUMBER" ,
"due":"2011-02-28T05:00:00Z",
"has_due_time":"0",
"added":"2011-02-21T05:04:49Z",
"completed":"",
"deleted":"",
"priority":"2",
"postponed":"0",
"estimate":""
}
}
}
}
}
}
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.
