Select only specific parts of the image

Question

I am completely new in "Optical character recognition" and need some more information and advices because I was not able to find is it possible to do what I need.

I have the following task:

1. An images are given as input - they will have the same structure - some icons and company symbols and text.
2. Only the text need to be selected and then make as text using some OCR library.

Is it possible to create a function using some OCR php library and select only some of the zones with text?

If there is not good OCR library for PHP, could you recommend me some on other languages?

The example below demonstrates what I want to do (this is just an example, I am not trying to do some out of the law manipulations with money):

This is sample image:

And this is the output (the text surrounded with red rectangles):

1. THIS IS LEGAL TENDER FOR ALL DEBTS, PUBLIC AND PRIVATE
2. L11180916G
3. ONEDOLAR

All articles and advices are welcomed.

I would recommend: https://github.com/tesseract-ocr/tesseract

PHP probably not the best tool for the job, but you can always call tesseract from PHP if you want to, then parse the results that you get out of it.
