Trouble retrieving video info from JSON data using PHP for and foreach loops - YouTube API 3

Basically I want to list the last uploads of a YouTube channel, but I had trouble using the for loop or I am missing foreach use as well.

I have tried the following:

function last_uploads() {
for($i = 0; $i < 20; ){
        error_reporting(E_ALL);
        $url =      'https://www.googleapis.com/youtube/v3/search?order=date&part=snippet&channelId=UCBR8-60-B28hp2BmDPdntcQ&maxResults=3&key={key}&type=video';
        $json = file_get_contents($url);
        $json_data = json_decode($json, false);
        $id = $json_data->items[0]->id->videoId;
                echo '<iframe id="ytplayer" type="text/html" width="auto" height="auto" 
                src="http://www.youtube.com/embed/' . $id . '?rel=0&showinfo=1"
                frameborder="0" allowfullscreen></iframe><br class="clear" />';
}
        $i++;
        break;
}

The output of the feed url ( $url ) is the following:

    {
 "kind": "youtube#searchListResponse",

     }
    },
    "channelTitle": "YouTube",
    "liveBroadcastContent": "none"
   }
  }
 ]
}

The issue is that last_uploads() returns the last 1 video and keeps repeating it until 120 seconds exceeded error appears.

Any thoughts?

Regards,

Thank you!

Thanks to @johnh10 [ answer ], deleting for loop got it working:

function last_uploads() {
        $url = 'https://www.googleapis.com/youtube/v3/search?order=date&part=snippet&channelId=UCBR8-60-B28hp2BmDPdntcQ&maxResults=3&key={key}&type=video';
        $json = file_get_contents($url);
        $json_data = json_decode($json, false);
        foreach ( $json_data->items as $item ) {
            $id = $item->id->videoId;
            echo '<iframe id="ytplayer" type="text/html" width="auto" height="auto" 
                src="http://www.youtube.com/embed/' . $id . '?rel=0&showinfo=1"
                frameborder="0" allowfullscreen></iframe><br class="clear" />';
        }
}

Thanks John :)

It's just messed up.

  1. Your for loop will execute indefinitely until timeout because the $i++ is AFTER the for loop. (Truth is, the for loop isn't even needed because you're fetching the latest 3 videos from the channel - no need to do that 20 times).

  2. Your code only fetches the id of the first video that is returned. This is where a for loop should be to loop through the results.

    foreach ( $json_data->items as $item ) { $id = $item->id->videoId; # print your stuff }
