如何在PHP的本地主机上正确设置Google Cloud Vision？

Question

I want to use Google cloud Vision for detecting image properties. I have created an account with Google Cloud and found the exact solution on one of their code snippet here ( https://cloud.google.com/vision/docs/detecting-properties#vision-image-property-detection-gcs-php ).

I copied and adjust it to what I want to achieve. I installed their package using composer google/cloud-vision .

So here is my code:

<?php 

namespace Google\Cloud\Samples\Vision;

use Google\Cloud\Vision\VisionClient;

 $projectId = 'YOUR_PROJECT_ID';
 $path = 'event1.jpg'; 

function detect_image_property($projectId, $path)
{
    $vision = new VisionClient([
        'projectId' => $projectId,
    ]);
    $image = $vision->image(file_get_contents($path), [
        'IMAGE_PROPERTIES'
    ]);
    $result = $vision->annotate($image);
    print("Properties:\n");
    foreach ($result->imageProperties()->colors() as $color) {
        $rgb = $color['color'];
        printf("red:%s\n", $rgb['red']);
        printf("green:%s\n", $rgb['green']);
        printf("blue:%s\n\n", $rgb['blue']);
    }
}

detect_image_property($projectId, $path); 


?> 

So when I run my code it throws this error:

Fatal error: Uncaught Error: Class 'Google\\Cloud\\Vision\\VisionClient' not found in C:\\xampp\\htdocs\\vision\\index.php:12 Stack trace: #0 C:\\xampp\\htdocs\\vision\\index.php(28): Google\\Cloud\\Samples\\Vision\\detect_image_property('YOUR_PROJECT_ID', 'event1.jpg') #1 {main} thrown in C:\\xampp\\htdocs\\vision\\index.php on line 12

Now am wondering what is the next step for me, also what will be my
$projectId = 'YOUR_PROJECT_ID'

*Please, if this question needs more explanation let me know in the comment instead of downvoting.

Thanks.

Project-Id : This is the private key, we've to generate using Google cloud vision for example - https://cloud.google.com/vision/docs/libraries#client-libraries-install-php

As per the error, we can say it's not able to find your file - Google\\Cloud\\Samples\\Vision;

To avoid this we've to load require __DIR__ . '/vendor/autoload.php'; require __DIR__ . '/vendor/autoload.php'; file before using them

namespace Google\Cloud\Samples\Vision;
