cant retrieve JSON object on localhost - php

Question

I'm trying to retrieve JSON Objects on my localhost, the issue is that it wont output anything. The JSON objects could look like following:
[
{
NAME: "Hearthstone",
PLAYER1: "Rdu ",
PLAYER2: "Savjz ",
status: 2,
meta: "LIVE"
},
{
NAME: "League of Legends",
PLAYER1: "Team King ",
PLAYER2: "EDG ",
status: 2,
meta: "28.12."
}]
php retrieve objects.
$url = "http://localhost:8888/crawl_JSON.php";
$json = file_get_contents($url);
$json_output = json_decode($json);
echo $json_output;
Why don't it output anything?

Answer 1

Note that json_decode() returns an object, you cannot echo you will need to use var_dump or print_r. If you want to echo , you can echo the JSON string.
$url = "http://localhost:8888/crawl_JSON.php";
$json = file_get_contents($url);
echo $json;
$json_output = json_decode($json);
var_dump($json_output);
And inside of crawl_JSON.php You need to echo the JSON, you will need to make sure it is valid.
<?php
echo '
[
{
"NAME": "Hearthstone",
"PLAYER1": "Rdu ",
"PLAYER2": "Savjz ",
"status": 2,
"meta": "LIVE"
},
{
"NAME": "LeagueofLegends",
"PLAYER1": "TeamKing",
"PLAYER2": "EDG",
"status": 2,
"meta": "28.12."
}
]
';
