How to echo JSON in PHP (stdClass Object)?

Question

This is a simple JSON but it cannot access an item. I send the that JSON to get.php and there just print_r the JSON and in parsing JSON response is problem.

My code:

$url = "http://localhost/get.php";    
    $data = array(
        'item1'      => 'value1',
        'item2'      => 'value2',
        'item3'      => 'value3'
    );


$content = json_encode($data);

$curl = curl_init($url);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HTTPHEADER,
array("Content-type: application/json"));
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, $content);

$json_response = curl_exec($curl);
$status = curl_getinfo($curl, CURLINFO_HTTP_CODE);

if ( $status == 201 ) {
die("Error: call to URL $url failed with status $status, response $json_response, curl_error " . curl_error($curl) . ", curl_errno " curl_errno($curl));
}


curl_close($curl);
$response = json_decode($json_response, false);
$result=json_encode($json_response);
$data=json_decode($result);

How can I echo item 1 or 2 ?

This is get.php

if ($_SERVER['REQUEST_METHOD'] == 'POST')
{
  $data = json_decode(file_get_contents("php://input"));
  print_r($data);
}

the json is irrelevant. once it's decoded, it's a PHP data structure, like any other PHP data structure. there will be absolutely NO trace within it that says "I used to be json". You access the data like any other php structure. — Marc B

Simple echo $result['item1'];, echo $result['item2']; will do. BTW there's no point encoding it, and then decoding it again. — Rajdeep Paul

What does this have to do with stdClass Object? When you use true as the second argument to json_decode() it returns an associative array, not an object. — Barmar

As Rajdeep just said, echo it based upon the name you gave the index, as you would any array. If you want to loop through, use a loop. — Fata1Err0r

Since get.php uses print_r(), it's not returning JSON. It needs to use json_encode().

if ($_SERVER['REQUEST_METHOD'] == 'POST')
{
  $data = json_decode(file_get_contents("php://input"));
  echo json_encode($data);
}

Then your curl script can decode it properly.

$response = json_decode($json_response, false);
echo 'Item1 = ' . $response->item1 . '<br>';
echo 'Item2 = ' . $response->item2 . '<br>';
echo 'Item3 = ' . $response->item3;

You don't need set second param in json_decode function for getting stdClass.

$data = array(
    'item1' => 'value1',
    'item2' => 'value2',
    'item3' => 'value3'
);
$json=json_encode($data);
$result=json_decode($json);
echo $result->item1;
echo $result->item2;
echo $result->item3;

Or you can work with array

$json=json_encode($data);
$result=json_decode($json, true);
echo $result['item1'];
echo $result['item2'];
echo $result['item3'];

use json_encode() to encode the data , then print the json

  $data = json_decode(file_get_contents("php://input"));
  echo json_encode($data);

curl_close($curl);
$result = json_decode($jsonResponse, true);
echo $result['item1']; //Echo item 1.

You can see the keys in the question, they're not numeric.

That's why i added the other answer. It looks like he doesn't get array as result though. http://php.net/manual/en/function.json-decode.php says json_decode($json, true) returns array...
