Installation

Versioning

This library doesn't use semantic versioning. The first two version numbers (X.Y out of X.Y.Z) follow the API (backend) versioning, and whenever the API gets updated, this library follows it.

The third version number (Z out of X.Y.Z) is used by this library for any independent releases of library-specific improvements and bug fixes.

Getting started

Construct the client and setup your API key or Personal Access Token in the metadata variable.

require ‘vendor/autoload.php’;
use Clarifai\ClarifaiClient;

$client = ClarifaiClient::grpc();
$metadata = ['Authorization' => ['Key {MY_CLARIFAI_API_KEY_OR_PAT}']];

Predict concepts in an image:

use Clarifai\Api\Data;
use Clarifai\Api\Image;
use Clarifai\Api\Input;
use Clarifai\Api\PostModelOutputsRequest;
use Clarifai\Api\Status\StatusCode;

[$response, $status] = $client->PostModelOutputs(
    new PostModelOutputsRequest([
        'model_id' => 'aaa03c23b3724a16a56b629203edc62c',  // This is the ID of the publicly available General model.
        'inputs' => [
            new Input([
                'data' => new Data([
                    'image' => new Image([
                        'url' => 'https://samples.clarifai.com/dog2.jpeg'
                    ])
                ])
            ])
        ]
    ]),
    $metadata
)->wait();

if ($status->code !== 0) throw new Exception("Error: {$status->details}");
if ($response->getStatus()->getCode() != StatusCode::SUCCESS) {
    throw new Exception("Failure response: " . $response->getStatus()->getDescription() . " " .
        $response->getStatus()->getDetails());
}

echo "Predicted concepts:\n";
foreach ($response->getOutputs()[0]->getData()->getConcepts() as $concept) {
    echo $concept->getName() . ": " . number_format($concept->getValue(), 2) . "\n";
}
