Google Cloud Vision PHP

This is a simple PHP interface to the Google Cloud Vision API.

Features:

• Supports almost all features of the Cloud Vision API (version 1).
• Loads images from files, URLs, raw data, or Google Cloud Storage.

Installation

Requirements:

• PHP ≥ 5.6
• API key (see Google's Getting Started documentation)

To install, first add this to your composer.json:

    "require": {
        "wikisource/google-cloud-vision-php": "^1.2"
    }

...and run composer update.

Usage

use GoogleCloudVisionPHP\GoogleCloudVision;

$gcv = new GoogleCloudVision();

// Get your API key from the Google Cloud Platform site.
$gcv->setKey("[Key from Google]");

// An image can be set from either a filename or URL (the default), raw data, or a Google Cloud Storage item:
$gcv->setImage("local/filesystem/file.png");
$gcv->setImage("https://example.org/url/to/file.png");
$gcv->setImage(file_get_contents('local/file.png'), GoogleCloudVision::IMAGE_TYPE_RAW);
$gcv->setImage("gs://bucket_name/object_name", GoogleCloudVision::IMAGE_TYPE_GCS);

// Set which features you want to retrieve:
$gcv->addFeatureUnspecified(1);
$gcv->addFeatureFaceDetection(1);
$gcv->addFeatureLandmarkDetection(1);
$gcv->addFeatureLogoDetection(1);
$gcv->addFeatureLabelDetection(1);
$gcv->addFeatureTextDetection(1);
$gcv->addFeatureDocumentTextDetection(1);
$gcv->addFeatureSafeSeachDetection(1);
$gcv->addFeatureImageProperty(1);

// Optional. The API will try to guess the language if you don't set this.
$gcv->setImageContext(['languageHints' => ['th']]);

$response = $gcv->request();
