How to display Json data using PHP? – SEO

I have a json file and I want to display its data in a PHP file. I tried with the code below but its not work.

$json_output = file_get_contents("https://gdata.youtube.com/feeds/api/playlists/PL3n6kxxrIGdat31ZIf_7wlqtT3I20OqLL?v=2&alt=jsonc");
$json = json_decode($json_output, true);


foreach($json->data->items->thumbnail as $day) {

   echo $day->sqDefault;
   echo $day->hqDefault;
}

and my json file is 

{"apiVersion":"2.1","data":{"id":"PL3n6kxxrIGdat31ZIf_7wlqtT3I20OqLL","author":"Tutorial top","title":"دورة سيو للمبتدئين [ali baba]","description":"","thumbnail":{"sqDefault":"https://i.ytimg.com/vi/XIhVZqCVqhs/default.jpg","hqDefault":"https://i.ytimg.com/vi/XIhVZqCVqhs/hqdefault.jpg"},"content":{"5":"http://www.youtube.com/p/PL3n6kxxrIGdat31ZIf_7wlqtT3I20OqLL"},"totalItems":31,"startIndex":1,"itemsPerPage":1,"items":[{"id":"PLH_kL5FgJPmdcYTGqaMXFsVJJ-pbR_YyiC1Y73R1tfYY","position":1,"author":"Tutorial top","video":{"id":"Kw8m5S2OhPs","uploaded":"2013-11-10T16:04:28.000Z","updated":"2014-02-18T17:59:36.000Z","uploader":"vkd-nAV91SLMCYNBKGJmsA","category":"People","title":"Beginners SEO Tutorial Course   Intro","description":"","thumbnail":

    Firstly, if you’d like to access the JSON structure as an object (as opposed to an array) drop the second argument of json_decode(), otherwise you end up with an array as $json. Have a look at the first example to see the difference.
    Then you should loop through the items array. Each of its elements has a video property, which has the thumbnailproperty you want

    $json_output = file_get_contents("https://gdata.youtube.com/feeds/api/playlists/PL3n6kxxrIGdat31ZIf_7wlqtT3I20OqLL?v=2&alt=jsonc");
$json = json_decode($json_output);
foreach ($json->data->items as $item) {
    echo $item->video->thumbnail->sqDefault;
    echo $item->video->thumbnail->hqDefault;
}

    should do the job. You can see it in action.

    To get a clear picture of the structure one of the many online available JSON viewers could help you 😉

    After many trials this is working fine.

    I have tested in my local system.

    Here is code:–

    <?php
$json_output = file_get_contents("https://gdata.youtube.com/feeds/api/playlists/PL3n6kxxrIGdat31ZIf_7wlqtT3I20OqLL?v=2&alt=jsonc");
$json = json_decode($json_output);
error_reporting(0);
foreach($json->data->thumbnail as $image) {
   echo $image.",|";
}

?>

    Output:-

    https://i.ytimg.com/vi/XIhVZqCVqhs/default.jpg,|https://i.ytimg.com/vi/XIhVZqCVqhs/hqdefault.jpg

    Hope this helps

    See that I remove the 2nd param in the json_decode() and I iterate with $json->data->items[0]->video->thumbnail and at the end I remove the final | with rtrim()

    You can use this example:

    <?php

$json_output = '{"apiVersion":"2.1","data":{"id":"PL3n6kxxrIGdat31ZIf_7wlqtT3I20OqLL","author":"Tutorial top","title":"دورة سيو للمبتدئين [ali baba]","description":"","thumbnail":{"sqDefault":"https://i.ytimg.com/vi/XIhVZqCVqhs/default.jpg","hqDefault":"https://i.ytimg.com/vi/XIhVZqCVqhs/hqdefault.jpg"},"content":{"5":"http://www.youtube.com/p/PL3n6kxxrIGdat31ZIf_7wlqtT3I20OqLL"},"totalItems":31,"startIndex":1,"itemsPerPage":1,"items":[{"id":"PLH_kL5FgJPmdcYTGqaMXFsVJJ-pbR_YyiC1Y73R1tfYY","position":1,"author":"Tutorial top","video":{"id":"Kw8m5S2OhPs","uploaded":"2013-11-10T16:04:28.000Z","updated":"2014-02-18T17:59:36.000Z","uploader":"vkd-nAV91SLMCYNBKGJmsA","category":"People","title":"Beginners SEO Tutorial Course   Intro","description":"","thumbnail":

//$json_output = file_get_contents("https://gdata.youtube.com/feeds/api/playlists/PL3n6kxxrIGdat31ZIf_7wlqtT3I20OqLL?v=2&alt=jsonc");

    $json = json_decode($json_output);
    $string = '';

    foreach($json->data->items[0]->video->thumbnail as $day) {


  $string .= $day . "|";
}

echo rtrim($string, '|');
