How can PHP be used to interact with the Google Drive API to retrieve file information?

To interact with the Google Drive API to retrieve file information using PHP, you will need to authenticate with Google, make API requests, and handle the response data accordingly. This can be achieved by using the Google API client library for PHP, which simplifies the process of interacting with Google APIs.

<?php

require_once 'vendor/autoload.php'; // Include the Google API client library

$client = new Google_Client();
$client->setAuthConfig('credentials.json'); // Set your credentials file
$client->addScope(Google_Service_Drive::DRIVE_METADATA_READONLY); // Set the scope for read-only access to file metadata

$service = new Google_Service_Drive($client);

$files = $service->files->listFiles(); // Retrieve a list of files from Google Drive

foreach ($files->getFiles() as $file) {
    echo "File Name: " . $file->getName() . "\n";
    echo "File ID: " . $file->getId() . "\n";
    echo "File Size: " . $file->getSize() . " bytes\n";
    echo "------------------------------------\n";
}

?>
