YouTube API: Upload Videos With PHP - Easy Guide

Hey guys! Ever wondered how to automate your YouTube uploads directly from your PHP application? Well, you're in the right place! In this guide, we'll dive deep into using the YouTube API with PHP to upload videos. This is super useful for things like automatically posting content from a website, creating a video-centric platform, or just automating your own workflow. Let's get started!

Setting Up Your Environment

Before we jump into the code, we need to set up our development environment. This involves getting the necessary API credentials from Google and installing the Google API client library for PHP.

1. Create a Google Cloud Project

First, head over to the Google Cloud Console and create a new project. This project will house all your API configurations and credentials. Give it a meaningful name, like "YouTube Uploader" or something similar. Make sure to select the project after it’s created.

2. Enable the YouTube Data API v3

Next, you need to enable the YouTube Data API v3 for your project. Search for "YouTube Data API v3" in the API Library and enable it. This API allows you to programmatically interact with YouTube, including uploading videos, managing playlists, and more.

3. Create API Credentials

Now, let's create the credentials we'll use to authenticate our PHP application. Go to the "Credentials" section in the Google Cloud Console. Click on "Create Credentials" and select "OAuth client ID." You'll need to configure the consent screen first if you haven't already. Fill in the necessary information, like the application name and support email.

For the application type, choose "Web application." Add authorized redirect URIs. This is the URL where Google will redirect the user after they authenticate your application. For local development, you can use http://localhost. For a live server, use your domain. Once you've configured the OAuth client ID, you'll get a client ID and a client secret. Keep these safe, as they are essential for authenticating your application.

4. Install the Google API Client Library for PHP

We’ll be using Composer to manage our dependencies. If you don't have Composer installed, get it from getcomposer.org. Once Composer is installed, navigate to your project directory in the terminal and run the following command:

composer require google/apiclient:^2.0

This command downloads and installs the Google API client library for PHP, along with its dependencies. This library provides the classes and functions needed to interact with the YouTube API.

Writing the PHP Code

Now that we have our environment set up, let's write some PHP code to upload videos to YouTube. We'll break this down into several steps:

1. Authentication

The first step is to authenticate our application with the YouTube API. We'll use the OAuth 2.0 flow to get an access token. This involves redirecting the user to Google's authentication page, where they can grant your application permission to access their YouTube account.

<?php
require_once 'vendor/autoload.php';

// Your client ID and client secret from the Google Cloud Console
$clientId = 'YOUR_CLIENT_ID';
$clientSecret = 'YOUR_CLIENT_SECRET';

// The redirect URI where Google will redirect the user after authentication
$redirectUri = 'http://localhost';

// Create a new Google API client
$client = new Google_Client();
$client->setClientId($clientId);
$client->setClientSecret($clientSecret);
$client->setRedirectUri($redirectUri);
$client->setScopes(['https://www.googleapis.com/auth/youtube.upload']);

// Create a YouTube service object
$youtube = new Google_Service_YouTube($client);

// Check if we have an access token in the session
session_start();
if (isset($_SESSION['access_token']) && $_SESSION['access_token']) {
    $client->setAccessToken($_SESSION['access_token']);
} else {
    // If we don't have an access token, redirect the user to Google's authentication page
    $authUrl = $client->createAuthUrl();
    header('Location: ' . filter_var($authUrl, FILTER_SANITIZE_URL));
}

// Handle the callback from Google after authentication
if (isset($_GET['code'])) {
    $token = $client->fetchAccessTokenWithAuthCode($_GET['code']);
    $client->setAccessToken($token);

    // Store the access token in the session for later use
    $_SESSION['access_token'] = $token;
}
?>

In this code:

• We include the autoload.php file from the vendor directory, which loads the Google API client library.
• We set the client ID, client secret, and redirect URI.
• We create a new Google_Client object and configure it with our credentials.
• We set the scope to https://www.googleapis.com/auth/youtube.upload, which allows us to upload videos to YouTube.
• We check if we have an access token in the session. If we do, we set it on the client. If not, we redirect the user to Google's authentication page.
• We handle the callback from Google after authentication. We fetch the access token using the authorization code and store it in the session.

2. Uploading the Video

Once we have an access token, we can upload the video to YouTube. Here's the code:

<?php
// ... (previous authentication code) ...

// Path to the video file
$videoPath = '/path/to/your/video.mp4';

// Video metadata
$videoTitle = 'My Awesome Video';
$videoDescription = 'This is a description of my awesome video.';
$videoCategory = '22'; // Entertainment category
$videoKeywords = 'awesome, video, entertainment';

// Create a new video resource
$video = new Google_Service_YouTube_Video();
$video->setSnippet(new Google_Service_YouTube_VideoSnippet());
$video->getSnippet()->setTitle($videoTitle);
$video->getSnippet()->setDescription($videoDescription);
$video->getSnippet()->setCategoryId($videoCategory);
$video->getSnippet()->setTags(explode(',', $videoKeywords));

// Set the video status
$video->setStatus(new Google_Service_YouTube_VideoStatus());
$video->getStatus()->setPrivacyStatus('private'); // or 'public' or 'unlisted'

// Specify the size of each chunk of data, in bytes. Setting a higher value results in
// fewer API requests as chunks are passed as you go.
$chunkSizeBytes = 1 * 1024 * 1024; // 1MB

// Setting the defer flag to true tells the client to return a request which can be called
// with ->execute(). This allows us to chunk the upload into smaller parts.
$client->setDefer(true);

// Create the API call to upload video
$insert = $youtube->videos->insert(
    'snippet,status',
    $video,
    array('mediaUpload' => new MediaFileUpload(
        $client,
        $youtube->videos->insert(
            'snippet,status',
            $video
        ),
        'video/*',
        file_get_contents($videoPath),
        'video/mp4',
        true
    ))
);

// Upload the video in chunks
$media = new Google_Http_MediaFileUpload(
    $client,
    $insert,
    'video/*',
    file_get_contents($videoPath)
);
$media->setFileSize(filesize($videoPath));
$media->setChunkSize($chunkSizeBytes);

// Read the media file and upload it chunk by chunk.
$status = false;
try {
    $status = $media->upload();

    while (!$status && is_array($status) && isset($status['progress'])) {
        printf("\r%3d%% Done", $status['progress']);
    }

    // If you want to make other calls after the file upload, set setDefer back to false
    $client->setDefer(false);

} catch (Google_Service_Exception $e) {
    echo '<p>A service error occurred: <code>' . htmlspecialchars($e->getMessage()) . '</code></p>';
} catch (Exception $e) {
    echo '<p>An client error occurred: <code>' . htmlspecialchars($e->getMessage()) . '</code></p>';
}


// Print the video ID if the upload was successful
if ($status) {
    echo "<h1>Video was uploaded successfully!</h1>";
    printf(" Video id '%s'\n", $status['id']);
}
?>

In this code:

• We specify the path to the video file, as well as the video metadata (title, description, category, and keywords).
• We create a new Google_Service_YouTube_Video object and set its snippet and status.
• We set the privacy status to private. You can change this to public or unlisted as needed.
• We create the API call to upload the video.
• We upload the video in chunks using Google_Http_MediaFileUpload.
• We print the video ID if the upload was successful.

3. Handling Errors

It's important to handle errors that may occur during the upload process. The code above includes try-catch blocks to catch Google_Service_Exception and Exception errors. These errors can occur if there are problems with the API request, the access token, or the video file.

Complete Example

Here's a complete example that combines the authentication and upload code:

<?php
require_once 'vendor/autoload.php';

// Your client ID and client secret from the Google Cloud Console
$clientId = 'YOUR_CLIENT_ID';
$clientSecret = 'YOUR_CLIENT_SECRET';

// The redirect URI where Google will redirect the user after authentication
$redirectUri = 'http://localhost';

// Path to the video file
$videoPath = '/path/to/your/video.mp4';

// Video metadata
$videoTitle = 'My Awesome Video';
$videoDescription = 'This is a description of my awesome video.';
$videoCategory = '22'; // Entertainment category
$videoKeywords = 'awesome, video, entertainment';

// Create a new Google API client
$client = new Google_Client();
$client->setClientId($clientId);
$client->setClientSecret($clientSecret);
$client->setRedirectUri($redirectUri);
$client->setScopes(['https://www.googleapis.com/auth/youtube.upload']);

// Create a YouTube service object
$youtube = new Google_Service_YouTube($client);

// Check if we have an access token in the session
session_start();
if (isset($_SESSION['access_token']) && $_SESSION['access_token']) {
    $client->setAccessToken($_SESSION['access_token']);
} else {
    // If we don't have an access token, redirect the user to Google's authentication page
    $authUrl = $client->createAuthUrl();
    header('Location: ' . filter_var($authUrl, FILTER_SANITIZE_URL));
    exit;
}

// Handle the callback from Google after authentication
if (isset($_GET['code'])) {
    $token = $client->fetchAccessTokenWithAuthCode($_GET['code']);
    $client->setAccessToken($token);

    // Store the access token in the session for later use
    $_SESSION['access_token'] = $token;
    header('Location: http://localhost'); // Redirect to the same page to prevent re-authentication
    exit;
}

// Create a new video resource
$video = new Google_Service_YouTube_Video();
$video->setSnippet(new Google_Service_YouTube_VideoSnippet());
$video->getSnippet()->setTitle($videoTitle);
$video->getSnippet()->setDescription($videoDescription);
$video->getSnippet()->setCategoryId($videoCategory);
$video->getSnippet()->setTags(explode(',', $videoKeywords));

// Set the video status
$video->setStatus(new Google_Service_YouTube_VideoStatus());
$video->getStatus()->setPrivacyStatus('private'); // or 'public' or 'unlisted'

// Specify the size of each chunk of data, in bytes. Setting a higher value results in
// fewer API requests as chunks are passed as you go.
$chunkSizeBytes = 1 * 1024 * 1024; // 1MB

// Setting the defer flag to true tells the client to return a request which can be called
// with ->execute(). This allows us to chunk the upload into smaller parts.
$client->setDefer(true);

// Create the API call to upload video
$insert = $youtube->videos->insert(
    'snippet,status',
    $video,
    array('mediaUpload' => new MediaFileUpload(
        $client,
        $youtube->videos->insert(
            'snippet,status',
            $video
        ),
        'video/*',
        file_get_contents($videoPath),
        'video/mp4',
        true
    ))
);

// Upload the video in chunks
$media = new Google_Http_MediaFileUpload(
    $client,
    $insert,
    'video/*',
    file_get_contents($videoPath)
);
$media->setFileSize(filesize($videoPath));
$media->setChunkSize($chunkSizeBytes);

// Read the media file and upload it chunk by chunk.
$status = false;
try {
    $status = $media->upload();

    while (!$status && is_array($status) && isset($status['progress'])) {
        printf("\r%3d%% Done", $status['progress']);
    }

    // If you want to make other calls after the file upload, set setDefer back to false
    $client->setDefer(false);

} catch (Google_Service_Exception $e) {
    echo '<p>A service error occurred: <code>' . htmlspecialchars($e->getMessage()) . '</code></p>';
} catch (Exception $e) {
    echo '<p>An client error occurred: <code>' . htmlspecialchars($e->getMessage()) . '</code></p>';
}


// Print the video ID if the upload was successful
if ($status) {
    echo "<h1>Video was uploaded successfully!</h1>";
    printf(" Video id '%s'\n", $status['id']);
}
?>

Remember to replace YOUR_CLIENT_ID, YOUR_CLIENT_SECRET, and /path/to/your/video.mp4 with your actual credentials and video file path.

Best Practices and Optimization

When working with the YouTube API, here are some best practices to keep in mind:

• Handle Errors Gracefully: Always include error handling in your code to catch exceptions and provide informative messages to the user.
• Use Chunked Uploads: For large video files, use chunked uploads to avoid timeouts and memory issues. The Google_Http_MediaFileUpload class handles this for you.
• Optimize Video Metadata: Use relevant titles, descriptions, and tags to improve the discoverability of your videos on YouTube.
• Cache Access Tokens: Store access tokens in a session or database to avoid re-authenticating the user every time you need to access the API.
• Monitor API Usage: Keep an eye on your API usage in the Google Cloud Console to avoid exceeding your quota.
