Hey,

Ik heb hier json data


[{"subcategory":"visual_arts",
"broadcast_part":2,
"featured":true,
"channel_subscription":false,
"id":"9700010016",
"category":"creativity",
"title":"Drawing: Mordesh! From WildStar.",
"channel_count":11,
"video_height":1152,
"site_count":0,
"embed_enabled":true,
"channel":{"category":"creativity",
"status":"Drawing: Mordesh! From WildStar.",
"subcategory":"visual_arts",
"language":"en",
"title":"foxberry_studios",
"channel_url":"http://www.justin.tv/foxberry_studios",
"producer":true,
"tags":null,
"subcategory_title":"Visual Arts",
"id":45251360,
"screen_cap_url_large":"http://static-cdn.jtvnw.net/previews-jtv/live_user_foxberry_studios-320x240.jpg",
"meta_game":"",
"mature":null,
"screen_cap_url_small":"http://static-cdn.jtvnw.net/previews-jtv/live_user_foxberry_studios-70x53.jpg",
"login":"foxberry_studios",
"timezone":"",
"screen_cap_url_medium":"http://static-cdn.jtvnw.net/previews-jtv/live_user_foxberry_studios-150x113.jpg",
"screen_cap_url_huge":"http://static-cdn.jtvnw.net/previews-jtv/live_user_foxberry_studios-630x473.jpg",
"category_title":"Creativity","views_count":612694},
"up_time":"Tue May 27 16:52:52 2014","format":"live",
"embed_count":0,
"stream_type":"live",
"abuse_reported":false,
"video_width":2048,
"geo":"US",
"name":"live_user_foxberry_studios",
"language":"en",
"stream_count":0,
"video_bitrate":1129.7109375,
"broadcaster":"obs",
"channel_view_count":0}]

En ik probeer bepaalde dingen aan een variable te plakken om later te kunnen printen / echo.
title, screen_cap_url_medium, channel_count, views_count etc

"title":"Drawing: Mordesh! From WildStar."
Voorbeeld :


$json_array = json_decode(file_get_contents('http://api.test.com/channel.json'), true);
$Title = $json_array['title'];
echo $Title;

Wil niet lukken, ik doe waarschijnlijk iets verkeerd.
Zou iemand mij kunnen helpen ?

Ten eerste heb je de json data structuur wat ongelukkig neergezet, waardoor je niet ziet dat 'channel' een object is en dat 'title' weer een property is van dat object:


[
    {
        "subcategory": "visual_arts",
        "broadcast_part": 2,
        "featured": true,
        "channel_subscription": false,
        "id": "9700010016",
        "category": "creativity",
        "title": "Drawing: Mordesh! From WildStar.",
        "channel_count": 11,
        "video_height": 1152,
        "site_count": 0,
        "embed_enabled": true,
        "channel": {
            "category": "creativity",
            "status": "Drawing: Mordesh! From WildStar.",

            "tags": null,
            "subcategory_title": "Visual Arts",
            "id": 45251360,
            "screen_cap_url_large": "http://static-cdn.jtvnw.net/previews-jtv/live_user_foxberry_studios-320x240.jpg",
            "meta_game": "",
            "mature": null,
            "screen_cap_url_small": "http://static-cdn.jtvnw.net/previews-jtv/live_user_foxberry_studios-70x53.jpg",
            "login": "foxberry_studios",
            "timezone": "",
            "screen_cap_url_medium": "http://static-cdn.jtvnw.net/previews-jtv/live_user_foxberry_studios-150x113.jpg",
            "screen_cap_url_huge": "http://static-cdn.jtvnw.net/previews-jtv/live_user_foxberry_studios-630x473.jpg",
            "category_title": "Creativity",
            "views_count": 612694
        },
        "up_time": "Tue May 27 16:52:52 2014",
        "format": "live",
        "embed_count": 0,
        "stream_type": "live",
        "abuse_reported": false,
        "video_width": 2048,
        "geo": "US",
        "name": "live_user_foxberry_studios",
        "language": "en",
        "stream_count": 0,
        "video_bitrate": 1129.7109375,
        "broadcaster": "obs",
        "channel_view_count": 0
    }
]

Je moet het dus een laag dieper zoeken:


<?php
$Title = $json_array['channel']['title'];
?>

Simpele manier om hier achter te komen is om na het omzetten van de json structuur gewoon even je array naar het scherm te printen


<?php
echo '<pre>';
print_r( $json_array );
exit;
?>

P.S. Kan zelfs zo zijn dat je $Title = $json_array[0]['channel']['title']; moet gebruiken, maar probeer dat zelf even uit.

Werkt perfect!
Die print_r( $json_array );
Is erg handig voor in de toekomst ;)

Thanks
