Creating Client for Amazon Comprehend with AWS for PHP

Question

I recently updated from version 1 of the AWS SDK for PHP to version 3 of the AWS SDK so that I could start testing scripts using the Comprehend and Textract applications. I was able to connect through version 3 and utilize S3 using the "new S3Client()" command. There's extensive documentation regarding functions for Comprehend and Textract, but I can't figure out what the similar new client string is for each service. I've tried:
$cc = new comprehendClient();
$cc = new AWSComprehend();
$cc = new createComprehend();
and more and none of these have worked. If anyone can recommend a fix that would be really helpful. Likewise, if there's an online code repository I should look at that would be helpful. I see plenty of code samples for S3, but none for other applications (at least with SDK for PHP). Thanks!

Answer 1

From the AWS Comprehend PHP documentation provided, a Comprehend client can be instantiated and called like below :

require 'vendor/autoload.php';

use Aws\Exception\AwsException;
use Aws\Comprehend\ComprehendClient;

/**
 * This code expects that you have AWS credentials set up per:
 * https://docs.aws.amazon.com/sdk-for-php/v3/developer-guide/guide_credentials.html
 */


$ComprehendClient = \Aws\Comprehend\ComprehendClient::factory(array(
    'credentials' => [
        'key'    => 'AKIAXXXXXX',
        'secret' => '+TsIDxxxxxxx',
    ],
    'region' => 'us-east-1',
    'version'  => 'latest',
));

$result = $ComprehendClient->detectDominantLanguage([
    'Text' => "Nakabibili pala ng durian sa U.S. supermarkets kasama ng mga epol. Galing siguro sa Thailand.", // REQUIRED
]);


echo $result;
