phpOCR ist not the best choice, I would recommend TesseractOCR for PHP "A wrapper to work with TesseractOCR inside your PHP scripts." https://github.com/thiagoalessio/tesseract-ocr-for-php
phpOCR 不是最好的选择，我会推荐 TesseractOCR for PHP “在 PHP 脚本中使用 TesseractOCR 的包装器。” https://github.com/thiagoalessio/tesseract-ocr-for-php

That's called OCR. (See http://en.wikipedia.org/wiki/Optical_character_recognition).
这就是所谓的OCR。（参见http://en.wikipedia.org/wiki/Optical_character_recognition）。
It's not a trival task (that's why captcha's work as good as they do).
这不是一项微不足道的任务（这就是为什么验证码的效果和它们一样好）。
You'd be better of googling 'OCR PHP' if you want to find solutions.
