Anagram finder

This tool is the result of an exercise (code kata, coding dojo) for test-driven development (TDD) for PHP using PHPUnit at Oliver Klee's workshops.

An anagram is pair of two words that consist of exactly the same letters, but in different order.

Example: anthologise, theologians

The dictionaries have been copied from the most-common-words-by-language project.

Installation

Run composer install to install the required Composer packages.

How to run it

bin/find-anagrams

You can also specify a dictionary to use from resources/dictionaries/:

bin/find-anagrams german.txt

The exercises

The big picture is this: "Find and output all anagrams from a text file with a list of words."

1. Create a class that reads a list of words from a file and returns it as an array.
2. Create a class that takes a word and sorts the characters.
3. Create a class that finds and returns the anagram from an array of words.
4. Deal with duplicates and empty lines in the file gracefully.
5. Find the anagrams in a case-insensitive way.
6. Sort the anagrams alphabetically during output.
