Images — php-opencloud 1.12.1 documentation

# Images

## List images

    $images = $service->listImages();

    foreach ($images as $image) {
       /** @param $image OpenCloud\Image\Resource\Image */
    }

## Get image details

    /** @param $image OpenCloud\Image\Resource\Image */
    $image = $service->getImage('{imageId}');

### A note on schema classes

Both `OpenCloud\Image\Resource\Image` and `OpenCloud\Image\Resource\Member` extend the `AbstractSchemaResource` class, which offers some unique functionality.

Because these resources are inherently dynamic - i.e. they are modelled on dynamic JSON schema - you need to access their state in a different way than conventional getter/setter methods, and even class properties. For this reason, they implement SPL’s native ArrayAccess interface which allows you to access their state as a conventional array:

    $image = $service->getImage('{imageId}');

    $id = $image['id'];
    $tags = $image['tags'];

## Update image

You can only update your own custom images - you cannot update or delete base images. The way in which you may update your image is dictated by its schema.

Although you should be able to add new and replace existing properties, always prepare yourself for a situation where it might be forbidden:

    use OpenCloud\Common\Exceptions\ForbiddenOperationException;

    try {
        $image->update(array(
            'name'        => 'foo',
            'newProperty' => 'bar'
        ));
    } catch (ForbiddenOperationException $e) {
        // A 403 Forbidden was returned
    }

There are three operations that can take place for each Image property:

- If a `false` or `null` value is provided, a `REMOVE` operation will occur, removing the property from the JSON document
- If a non-false value is provided and the property does not exist, an `ADD` operation will add it to the document
- If a non-false value is provided and the property does exist, a `REPLACE` operation will modify the property in the document

## Delete image

    $image->delete();
