I would like to try to read some of text from an image with PHP.
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.
http://en.wikipedia.org/wiki/Optical_character_recognition
There is a package available, called phpOCR, that does exactly what you need.
http://sourceforge.net/projects/phpocr/


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


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.

im new in Webdevelopment and I wanted to ask you ("THE EXPERTS") if you could guide me or give some hints how to do following Webpage:
I want to upload 3-5 Images, place them automatically horizontally on a PDF and let the user download the PDF. I don't want to store the images so after you reload the page the images should be gone.
Could you help me how to realize such webpage? Or atleast which way I should use? Jscript, html5, php etc...
Best regards
Machete

You are looking for a pdf-libary like FPDF.
Especially take a look at the Image() function (Documentation).

quick and dirty, create a php script that executes something like this on the shell:
convert image1.png image2.png image3.png output.pdf
you need to have imagemagick installed.
There are more elegant ways to do that.

I wrote web service which will generate label from certain parameters and will return it as PDF. Now I must improve it by returning generated label as PDF or ZPL format.
Unfortunately, I have zero knowledge on working with ZPL. What is ZPL? Is it some kind of file format? What is used for? How its generated? Any open-source PHP libraries for it?
It would be nice if someone would provide some whitepapers or some kind of reference about ZPL.
Web service is written in PHP.

So in which direction i should work to do this thing? There are default tools for this?

What you need is a face detection tool. For PHP, I know this script:
https://github.com/mauricesvay/php-facedetection
(Here is the detailed usage: http://www.codediesel.com/algorithms/face-detection-in-images-using-php/)
Just for fun, take a look in Google's Algorithm for Maps License Plate Blur tool:

Have a look to this library: phpOCR

Thank You in advance.

You are coping what is usually refered as "longest common subsequence problem", there are a looot of implementations of the most common algorithm. You can spot the solution of your problem working on the script provided here.

You could use the Text_Diff pear package which is pretty robust. There's also the xdiff extension, which you can do this with, using the xdiff_file_diff function
xdiff_file_diff('Old_file.txt', 'new_file.txt', 'diff.txt');
Where diff.txt would be the resulting file with the comparison between the two files.
