    You need to install Tesseract OCR on your pc from here:
    https://github.com/tesseract-ocr/tesseract

    Then your code should be(just in case you are on windows, C:Program FilesTesseract-OCRtesseract.exe is the path of Tesseract engine):

    echo (new TesseractOCR($img_url))
        ->executable('C:Program FilesTesseract-OCRtesseract.exe')
        ->whitelist(range('A', 'Z'))
        ->lang('eng')
        ->run();

    Make sure the tesseract folder is in your path.

    If you’re unsure what I’m saying, click on the start button and type "edit the system environment variables". Click Environment Variables, under "System variables" click on the line that has "Path" on the far left, and click edit. Click "New" and put in the path to your executable, depending on if you’re using the 64 bit or 32 bit version. In my case it was "C:Program FilesTesseract-OCR".

    You can test this now by opening a new command prompt (if you had an old one open, it won’t have the new path variable), and type tesseract and hit enter. You should see:

    Usage:
  tesseract --help | --help-extra | --version
  tesseract --list-langs
  tesseract imagename outputbase [options...] [configfile...]

OCR options:
  -l LANG[+LANG]        Specify language(s) used for OCR.
NOTE: These options must occur before any configfile.

Single options:
  --help                Show this help message.
  --help-extra          Show extra help for advanced users.
  --version             Show version information.
  --list-langs          List available languages for tesseract engine.

    If you do, then it’s installed and globally working on your machine now and should work with PHP. If you want to get it working without composer, look up my other answer about that on here.
