I am building a small interface to show livestreamed video from a YouTube channel to a webpage. I got the API key, I set it up and it worked. But then I couldn't access certain information from the json I got back from the YouTube server.
I tried a few things, fixing whatever breaks on the go, but I realised that sometimes it works and sometimes it doesn't... I searched other threads but I can't understand anymore what's happening.
So the questions are:
How to use file_get_contents_url() to get info about a Youtube channel every time without HTTP response failure?
Why is my testing using all the units I have as a quota from Google's API? (It runs out of units in a 50 refreshes or so)
My code
<?php
header("Access-Control-Allow-Origin: *");
# Enable Error Reporting and Display:
error_reporting(~0);
ini_set('display_errors', 1);
$API_KEY = 'API KEY HERE';
$ChannelID = ' CHANNEL ID HERE';
$channelInfo = 'https://www.googleapis.com/youtube/v3/search?part=snippet&channelId='.$ChannelID.'&type=video&eventType=live&key='.$API_KEY;
$extractInfo = file_get_contents_url($channelInfo);
$extractInfo = str_replace('},]',"}]",$extractInfo);
$showInfo = json_decode($extractInfo, true);
if($showInfo['pageInfo']['totalResults'] === 0){
echo 'Users channel is Offline';
}else{
echo 'Users channel is LIVE!';
}
$videoId = $extractInfo['items'][0]['id']["videoId"];
if ($videoId = 0) {
echo "<h2>No live stream yet.</h2>";
} else {
echo "</h2>$videoId</h2>";
}
?>
What I need is:
- to access my YouTube channel,
- get the content as json,
- turn it into a php array,
- where I get the videoId of the livestreamed video
- and display it.
When I echo $extractInfo
I get
{
