An abstract PHP class which can be extended to create a program that accepts multiple lines of input and return output.
An extending class must implement a method called readLine. This is the function called after each line of input.
If readLine() returns false, the program will exit.
To run demo:
cd demos
php run_demo.php
php run_demo.php < input.txt
- Add an interface to be implemented by line readers, instead of extending main class.
