json decode returning empty array - php

Question

I am trying to retrieve an array from an API, but every time it is returning an empty array after every attempt.
This is my coding which is fetching data from api:
<?php
$array=array("name"=>"name1");
$url = "http://getsjobs.esy.es/registerapi.php?".http_build_query($array);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$json = curl_exec($ch);
curl_close($ch);
$data = json_decode($json,true);
if (is_array(json_decode($data )) || is_object(json_decode($data)))
{ echo 'array exists'; }
else { echo 'Not an array'; }
?>
this is my api code
<?php
if(isset($_GET['Array'])) {
$array = $_GET['Array'];
header('Content-type: application/json');
}
?>
Even if i use json_encode($array). It is returning empty array. I can receive single value or single array element, but not able to send and receive entire
array from json.
I am not able to find any relevant post. Any link or suggestion will be helpful

Answer 1

My PHP is rusty, but the problem looks to me to be because your API is looking for a parameter called "Array", but nowhere in your calling block does it actually send a GET parameter called "Array".
Your code looks a bit incomplete, so maybe I'm misunderstanding something.

look here: you're decoding it twice.
$data = json_decode($json,true);
if (is_array(json_decode($data )) || is_object(json_decode($data)))
{ echo 'array exists'; }
else { echo 'Not an array'; }
simply:
$data = json_decode($json,true);
if (is_array($data ))
{ echo 'array exists'; }
else { echo 'Not an array'; }
if it still doesn't works, see what echo json_last_error_msg(); returns.
Try to check if your $json is a valid json too. Check if what echo $json; returns is valid here: http://jsonformatter.curiousconcept.com/
