lire lien JSON avec php

bonjour à tous

je decouvre le json , et j'ai bloque sur un truc
voici le code utilisé :
<?php
$json = file_get_contents("http://xxxxxxxxxxxxxx/streaminfo.get");
var_dump(json_decode($json, true));
$parsed_json = json_decode($json);
$resultat = $parsed_json->{'type'};
echo $resultat ;

?>
en retour j'ai ça
array(2) { ["type"]=> string(6) "result" ["data"]=> array(1) { [0]=> array(19) { ["title"]=> string(10) "lien" ["song"]=> string(42) "Frida - I Know There´s Something Going On" ["track"]=> array(5) { ["artist"]=> string(5) "Frida" ["title"]=> string(34) "I Know There´s Something Going On"
et pour $resultat j'ai bien "result" par contre j'arrive pas a aller chercher ["artist"]=> string(5) "Frida" et ["title"]=> string(34) "I Know There´s Something Going On"
pour récupérer l’interprète + le titre 
$resultat = $parsed_json->{'type'};
apres le type j'ai testé plusieurs truc rien a faire la var $resultat reste vide

j'ai testé 
$resultat = $parsed_json->{'type'}->{'title};
je devrais avoir "lien" mais rien

oui ya 2 "title" moi je veux aller chercher le second
mais je bloque ...

besoin de vos lumieres :)

Hello,

Ton code est brouillon.

Pour faire simple, peux tu nous donner le contenu de ton json de base $json ?

Merci :)

apres passage dans php
array(2) { ["type"]=> string(6) "result" ["data"]=> array(1) { [0]=> array(19) { ["title"]=> string(10) "80" ["song"]=> string(22) "Michel Sardou - Musica" ["track"]=> array(5) { ["artist"]=> string(13) "Michel Sardou" ["title"]=> string(6) "Musica" ["album"]=> string(0) "" ["royaltytrackid"]=> int(0) ["imageurl"]=> string(63) "nocover.png" } ["bitrate"]=> string(7) "64 Kbps" ["server"]=> string(6) "Online" ["autodj"]=> string(6) "Online" ["source"]=> string(3) "Yes" ["offline"]=> bool(false) ["summary"]=> string(106) "80 - Michel Sardou - Musica" ["listeners"]=> int(1) ["maxlisteners"]=> int(100) ["reseller"]=> int(0) ["serverstate"]=> bool(true) ["sourcestate"]=> bool(true) ["sourceconn"]=> int(1) ["date"]=> string(12) "Feb 15, 2014" ["time"]=> string(8) "06:39 PM" ["rawmeta"]=> string(22) "Michel Sardou - Musica" ["url"]=> string(33) "/rpc" } } } 
array(2) {
    ["type"]=> string(6) "result" 
    ["data"]=> array(1) { 
    		[0]=> array(19) { 
            	["title"]=> string(10) "80"

     		["time"]=> string(8) "06:39 PM" 
     		["rawmeta"]=> string(38) "Michel Sardou - Musica" 
     		["url"]=> string(33) "/rpc" 
     		} 
	}

Salut,

Tu y était presque, mais data est un tableau, il faut donc accéder à son premier élément pour en récupérer les infos : 
$json_brut = '{
    "type": "result",
    "data": [
        {
            "title": "80",
            "song": "Michel Sardou - Musica",
            "track": {
                "artist": "Michel Sardou",
                "title": "Musica",
                "album": "",
                "royaltytrackid": 0,
                "imageurl": "nocover.png"
            },
            "bitrate": "64 Kbps",
            "server": "Online",
            "autodj": "Online",
            "source": "Yes",
            "offline": false,
            "summary": "80-MichelSardou-Musica",
            "listeners": 1,
            "maxlisteners": 100,
            "reseller": 0,
            "serverstate": true,
            "sourcestate": true,
            "sourceconn": 1,
            "date": "Feb15,2014",
            "time": "06: 39PM",
            "rawmeta": "MichelSardou-Musica",
            "url": "rpc"
        }
    ]
}';

$json = json_decode($json_brut, true);

var_dump($json['data'][0]['song']); // Michel Sardou - Musica
Bonne journée
