What is wrong with my PHP and json - php

Question

I am trying to get a response from my json array:
stdClass Object ( [Foo] => stdClass Object ( [id] => 0001 [name] => Foo [profileIconId] => 550 [summonerLevel] => 30 [revisionDate] => 1408463933000 ) )
using my current code, I know that it is really easy to solve - but I don't know what I am doing wrong as I can't find anything similar to this from what I am searching:
api.php:
<?php
class runeapi {
const get_id_na = 'https://na.api.pvp.net/api/lol/na/v1.4/summoner/by-name/';
const get_id_euw = 'https://euw.api.pvp.net/api/lol/euw/v1.4/summoner/by-name/';
const key = '...';
public function getID($summoner_name) {
$name = $summoner_name;
$call = self::get_id_euw .$name;
return $this->request($call);
}
private function request($call) {
$url = $call. '?api_key=' .self::key;
$json = file_get_contents($url);
$decode = json_decode($json);
$result = $decode; //<-- This is the Issue.
return $result;
}
}
?>
testing.php:
<?php
include('api.php');
$summoner_name = 'Foo';
$test = new runeapi;
$r = $test->getID($summoner_name);
print_r($r);
?>
$r returns $result
I'd like to be able to call for id but no matter where I tried looking, I couldn't find an example similar to what I have.
What I've tried:
$decode->{'id'};
$decode{'id'};

Answer 1

I believe this will work for you
private function request($call) {
$url = $call. '?api_key=' .self::key;
$json = file_get_contents($url);
return $json;
}
No need to decode it.

Answer 2

I had to add another variable to request():
public function getID($summoner_name) {
$name = $summoner_name;
$call = self::get_id_euw .$name;
return $this->request($call, $name); //<-- added $name
}
private function request($call, $name) { //<-- added $name
$url = $call. '?api_key=' .self::key;
$json = file_get_contents($url);
$decode = json_decode($json);
$result = $decode->{$name}->{'id'}; //<-- added $name
return $result;
}
