<?php

if (!file_exists(__DIR__ . '/vendor/autoload.php')) {

throw new \Exception('please run "composer require google/apiclient:~2.0" in "' . __DIR__ .'"');

}

require_once __DIR__ . '/vendor/autoload.php';

session_start();

//add your auth 2 client id and client secret here

$OAUTH2_CLIENT_ID = "PUT YOUR CLIENT ID";

$OAUTH2_CLIENT_SECRET = "PUT YOUR CLIENT SECRET ";

$client = new Google_Client();

$client->setClientId($OAUTH2_CLIENT_ID);

$client->setClientSecret($OAUTH2_CLIENT_SECRET);

$client->setScopes('https://www.googleapis.com/auth/youtube');

$redirect = filter_var('http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF'],

FILTER_SANITIZE_URL);

$client->setRedirectUri($redirect);

// Define an object that will be used to make all API requests.

$youtube = new Google_Service_YouTube($client);

// Check if an auth token exists for the required scopes

$tokenSessionKey = 'token-' . $client->prepareScopes();

if (isset($_GET['code'])) {

if (strval($_SESSION['state']) !== strval($_GET['state'])) {

die('The session state did not match.');

}

$client->authenticate($_GET['code']);

$_SESSION[$tokenSessionKey] = $client->getAccessToken();

header('Location: ' . $redirect);

}

if (isset($_SESSION[$tokenSessionKey])) {

$client->setAccessToken($_SESSION[$tokenSessionKey]);

}

// Check to ensure that the access token was successfully acquired.

if ($client->getAccessToken()) {

$htmlBody = '';

try{

// REPLACE this value with the path to the file you are uploading.

$videoPath = "video/test.mp4";

// Create a snippet with title, description, tags and category ID

// This example sets the video's title, description, keyword tags, and

// video category.

$snippet = new Google_Service_YouTube_VideoSnippet();

$snippet->setTitle("Test video title");

$snippet->setDescription("Test video description");

$snippet->setTags(array("tag1", "tag2"));

// Numeric video category. See

// https://developers.google.com/youtube/v3/docs/videoCategories/list

//put the video category ID here

$snippet->setCategoryId("22");

// Set the video's status to "public". Valid statuses are "public",

// "private" and "unlisted".

$status = new Google_Service_YouTube_VideoStatus();

$status->privacyStatus = "public";

// Associate the snippet and status objects with a new video resource.

$video = new Google_Service_YouTube_Video();

$video->setSnippet($snippet);

$video->setStatus($status);

// Specify the size of each chunk of data, in bytes. Set a higher value for

// reliable connection as fewer chunks lead to faster uploads. Set a lower

// value for better recovery on less reliable connections.

$chunkSizeBytes = 1 * 1024 * 1024;

// Setting the defer flag to true tells the client to return a request which can be called

// with ->execute(); instead of making the API call immediately.

$client->setDefer(true);

// Create a request for the API's videos.insert method to create and upload the video.

$insertRequest = $youtube->videos->insert("status,snippet", $video);

// Create a MediaFileUpload object for resumable uploads.

$media = new Google_Http_MediaFileUpload(

$client,

$insertRequest,

'video/*',

null,

true,

$chunkSizeBytes

);

$media->setFileSize(filesize($videoPath));

// Read the media file and upload it chunk by chunk.

$status = false;

$handle = fopen($videoPath, "rb");

while (!$status && !feof($handle)) {

$chunk = fread($handle, $chunkSizeBytes);

$status = $media->nextChunk($chunk);

}

fclose($handle);

// If you want to make other calls after the file upload, set setDefer back to false

$client->setDefer(false);

$htmlBody .= "<h3>Video Uploaded</h3><ul>";

$htmlBody .= sprintf('<li>%s (%s)</li>',

$status['snippet']['title'],

$status['id']);

$htmlBody .= '</ul>';

} catch (Google_Service_Exception $e) {

$htmlBody .= sprintf('<p>A service error occurred: <code>%s</code></p>',

htmlspecialchars($e->getMessage()));

} catch (Google_Exception $e) {

$htmlBody .= sprintf('<p>An client error occurred: <code>%s</code></p>',

htmlspecialchars($e->getMessage()));

}

$_SESSION[$tokenSessionKey] = $client->getAccessToken();

} elseif ($OAUTH2_CLIENT_ID == 'PUT YOUR CLIENT ID') {

$htmlBody = <<<END

<h3>Client Credentials Required</h3>

<p>

You need to set <code>\$OAUTH2_CLIENT_ID</code> and

<code>\$OAUTH2_CLIENT_ID</code> before proceeding.

<p>

END;

} else {

// If the user hasn't authorized the app, initiate the OAuth flow

$state = mt_rand();

$client->setState($state);

$_SESSION['state'] = $state;

$authUrl = $client->createAuthUrl();

$htmlBody = <<<END

<h3>Authorization Required</h3>

<p>You need to <a href="$authUrl">authorize access</a> before proceeding.<p>

END;

}

<!doctype html>

<html>

<head>

<title>Video Uploaded</title>

</head>

<body>

<?=$htmlBody?>

</body>

</html>

copy this php script and make upload.php file.
make sure that the file path should be http://localhost/youtubeapi/upload.php
because we added this url when we create auth 2 credentials. if not ,you should edit/add url in credentials page as below steps
https://console.developers.google.com/apis/credentials

you can edit/add callback url.
and then you should download google client files using composer
you need to install composer to your computer if not installed yet.
https://getcomposer.org/download/

if installed , runcommand prompt as administrator .
and put your upload.php file location and run composer command like below
cd C:\xampp\youtubeapi
composer require google/apiclient:^2.0
and enter.you should wait for while to download all required file.

now is time to run your uploader
if you get error message like this

Client Credentials Required

You need to set $OAUTH2_CLIENT_ID and $OAUTH2_CLIENT_ID before proceeding.
