PHP Include - error in opening the stream - php

Question

I am using an application that I downloaded using Composer.
The package has many classes that can be called and utilized.
However, when I run the below code, I am getting the following error.
<?php
error_reporting(E_ALL);
ini_set('display_errors', 'On');
include 'vendor/autoload.php';
$clarifai = new \DarrynTen\Clarifai\Clarifai('CLARIFAI_API_KEY');
$input = new Input();
$input->setImage('https://samples.clarifai.com/metro-north.jpg')->isUrl();
$inputResult = $clarifai->getInputRepository()->add($input);
echo json_encode($inputResult);
?>
Error:
Warning:
include(/var/www/html/vendor/darrynten/clarifai-php/src/Entity):
failed to open stream: Not a directory in /var/www/html/ctest.php on
line 7
Warning: include(): Failed opening

Fatal error: Uncaught Error: Class 'Input' not found in

/var/www/html/ctest.php on line 11
The class Input is located at /var/www/html/vendor/darrynten/clarifai-php/src/Entity which I am including using the include keyword in PHP right after the first include, of no avail.
include 'vendor/autoload.php';
include '/var/www/html/vendor/darrynten/clarifai-php/src/Entity';
Later, I used the following code
$concept = new \DarrynTen\Clarifai\Entity\Concept();
$concept->setId('boscoe')->setValue(true);
$input = new \DarrynTen\Clarifai\Entity\Input();
$input->setImage('https://samples.clarifai.com/puppy.jpeg')->isUrl()
->setConcepts([$concept]);
$inputResult = $clarifai->getInputRepository()->add($input);
on the last line, I am getting this error. (Guzzle related)
Fatal error: Uncaught GuzzleHttp\Exception\ClientException: Client

Is this also name space related?

Answer 1

I have found a new PHP library that seems to be compatible with new apps in Clarifai created with the new api_key version: phpfanatic/clarifai
You can easily try to install it via composer:
composer require phpfanatic/clarifai
As dependencies you need to have:
PHP - 5.6, 7.0 - May work with ealier version, untested at this time.
cURL - *
Clarifai API Key - clarifai
PHPUnit - to run tests (optional).
Here you can find the full documentation with quick tutorial or step by step explanation.

Answer 2

Eddie from Clarifai here. Sorry you ran into an issue.
I see that you are using an API key. This community library currently only supports our old auth mechanism. All new "apps" in Clarifai are only created with an api_key as opposed to client_id and client_secret.
There's currently a PR open to add support for API keys.
We're hoping to have first class PHP support by the end of the year.
