How to setup and running Tesseract OCR for PHP (opensource)?

问题

I have installed the Tesseract OCR via MacPorts based on the documentation provided on the GitHUb, and they were installed successfully, and

However, I am trying to use Tesseract OCR for PHP (https://github.com/thiagoalessio/tesseract-ocr-for-php), so I download the zip and include the library to my php file, and use the

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

but nothing is showing up.

Below is the full code in the php

<?php 

REQUIRE_ONCE __DIR__.'/src/TesseractOCR.php';

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

?>

My error log has this entry:

sh: tesseract: command not found

If you share me some lights on how to get this work, it will be great!
