So if I have an image like this:
How can I extract the text "Some text" into a string.
All help and suggestions are appreciated.
The process you are looking for is called Optical Character Recognition.
There is a package available, called phpOCR, that does exactly what you need.
That's called OCR. (See 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).
You'd be better of googling 'OCR PHP' if you want to find solutions.
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
