Estimating our total subscriber influence

If you can get members to submit their YouTube Channel ID's, as I presume you have in the works for the Virtual Membership system -

Simply build a comma separated array of Channel ID's - in this format - channelId,channelId,channelId,channelId

Then run it through this PHP script and it will tell you the exact amount of subscribers totalled from the provided Channel ID's without having to estimate!

*Note* You will need your own Data API Key, and to feed your created array in to the $userChannelsArray string, by default I've selected 3 Channel ID's to demonstrate it working.

Here's the API's Explorer for the functionality reference - developers.google.com/apis-explorer/#p/youtube/v3/youtube.channels.list?part=snippet%252CcontentDetails%252Cstatistics&id=UCv9Edl_WbtbPeURPtFDo-uA%252CUCIveFvW-ARp_B_RckhweNJw%252CUCC3L8QaxqEGUiBC252GHy3w&_h=3&


<?php



$api_key = "YOUR_YOUTUBE_API_KEY";



$userChannelsArray = "UCv9Edl_WbtbPeURPtFDo-uA,UCIveFvW-ARp_B_RckhweNJw,UCC3L8QaxqEGUiBC252GHy3w";



$tallySubscribers = 0;

$_SESSION['newChannel'] = array();

$url = "https://www.googleapis.com/youtube/v3/channels?part=snippet%2CcontentDetails%2Cstatistics&id=$userChannelsArray&key=$api_key";

$arr_list = channelsList($url);

foreach ($arr_list as $alist) {

foreach ($alist as $list) {

$newId = ($list->id);

$newStatSubscribers = ($list->statistics->subscriberCount);

$tallySubscribers = ($tallySubscribers + $newStatSubscribers);

}

}

function channelsList($api_url) {

$arr_result = json_decode(file_get_contents($api_url));

if (isset($arr_result->items) && !empty($arr_result->items)) {

$_SESSION['newChannel'][] = $arr_result->items;

}

return $_SESSION['newChannel'];

}

echo "The array of channels has a total of ".$tallySubscribers." subscribers!";

?>

This script could very easily be modified to also tally total videos / views if needed as well.

Let me know if you need any more information.
