I'm just starting to experiment with Google Document AI using the PHP client library, but see the sample code documentation for this is for version 1, which does not work in the current version of the PHP client library.

Specifically, I'm trying to find the current-version code for passing a raw document to a Document AI processor instance we've set up in Google Cloud, using the console.

The version 1 approach to this is shown in this documentation:

Here's the PHP code they list:

# Includes the autoloader for libraries installed with composer
require __DIR__ . '/vendor/autoload.php';

# Imports the Google Cloud client library
use Google\Cloud\DocumentAI\V1\DocumentProcessorServiceClient;
use Google\Cloud\DocumentAI\V1\RawDocument;

$projectId = 'YOUR_PROJECT_ID'; # Your Google Cloud Platform project ID
$location = 'us'; # Your Processor Location
$processor = 'YOUR_PROCESSOR_ID'; # Your Processor ID

# Create Client
$client = new DocumentProcessorServiceClient();

# Local File Path
$documentPath = 'resources/invoice.pdf';

# Read in File Contents
$handle = fopen($documentPath, 'rb');
$contents = fread($handle, filesize($documentPath));
fclose($handle);

# Load File Contents into RawDocument
$rawDocument = new RawDocument([
    'content' => $contents,
    'mime_type' => 'application/pdf'
]);

# Fully-qualified Processor Name
$name = $client->processorName($projectId, $location, $processor);

# Make Processing Request
$response = $client->processDocument($name, [
    'rawDocument' => $rawDocument
]);

# Print Document Text
printf('Document Text: %s', $response->getDocument()->getText());

The part I'm not able to make work with the current client library is the "#Make Processing Request" section. What is the current-version code for this?

And is documentation available anywhere for using the current PHP client library with Document AI?

Thank you!

Technically the latest version for Google Cloud Document AI for PHP is 2.1.3. This repository is part of Google Cloud PHP. Any support requests, bug reports, or development contributions should be directed to that project.

Based on this public documentation Document AI client libraries, we must install the client library, set up authentication and use the client library.
