How to use Tesseract PHP wrapper on wamp server

I used composer to install this Tesseract PHP wrapper : https://github.com/thiagoalessio/tesseract-ocr-for-php by typing the following command line directly from my php project folder located at C:/wamp/www/project_folder:

$ composer require thiagoalessio/tesseract_ocr

I created a php file called 'new' in the same folder where i try to use tesseract by typing :

use thiagoalessio\TesseractOCR\TesseractOCR;
echo (new TesseractOCR('text.png'))
->run();

I get the following error :

Fatal error: Class 'thiagoalessio\TesseractOCR\TesseractOCR' not found in C:\wamp\www\project_folder\new.php on line 4

Here's the content of my project folder :

   vendor(a folder)
   composer.json 
   composer.lock
   new.php 
   test.png

I have wampserver version 2.5 I have already installed tesseract (version 4) at C:program files I included the following code to my php file in order to set the path but still encoutering the error.

$path = getenv('PATH');
putenv("PATH=$path:C:\Program Files\Tesseract_OCR");

Solution

Does new.php contain the include for autoload.php? You most probably have to add require_once __DIR__ . '/vendor/autoload.php'; at the top of that file
