I need one class for optical recognition of characters from an image file to convert into a text file.
This is not a trivial problem but there is a package for that.
It can train the recognition engine with images of existing letters. Once the training is done it can start recognizing text in the pictures.
It is not limited to the letters provided for training. So you can improve the recognition capabilities adding more pictures of other letters you want it to recognize.
It just seems to not be able to take TIFF images as input format, but you can convert the TIFF images to PNG format.

maybe the tesseract ocr engine can help you to recognize characters from images. tesseract have php wrapper, so you can use it in php class. there is a free online ocr online-code.net/ocr.html using tesseract, you can have a try.
