Word List Comparator

Author: Roberto Aleman, ventics.com

A simple and efficient web tool for comparing two lists of words. It allows users to identify common, exclusive, and duplicate words, and offers the option to generate new, unified lists.

? Key Features

• User-Friendly Interface: Allows users to upload text files or paste word lists directly.
• Comprehensive Analysis: Provides a detailed report that includes: Internally Duplicated Words*: Identifies words that are repeated within each list. Exclusive Words*: Shows words that are only in List 1 or only in List 2. Common Words*: Lists words that appear in both lists, indicating their first position and number of repetitions.
• Data Normalization: Performs case-insensitive comparisons and cleans content by removing whitespace and empty lines.
• File Generation: Allows the creation of a text file (`newlist.txt`) with words found in both lists.
• List Unification: Offers the option to display a unified list with all unique words from both lists.

? How to Use

Simply upload the index.php and ListComparator.php files to the same folder on your web server. Then, open index.php in your browser.

1. Enter Lists: You can choose one of two options to input your data: Upload Files*: Use the "upload a text file" fields to select two files from your computer. Copy and Paste*: Paste the words directly into the provided text areas.
2. Configure Options: Check the boxes according to your needs: * `Unify lists with unique occurrences`: Displays a list with all unique words from both lists. * `Create a new file with common words`: Generates a file named `newlist.txt` with words found in both lists.
3. Compare: Click the `Compare Lists` button to run the analysis. The results will be displayed directly on the web page.

?? Project Structure

• `index.php`: Contains the user interface (HTML) and the logic to process form data. This is the main file users interact with.
• `ListComparator.php`: Defines the `ListComparator` class, which encapsulates all the business logic: data normalization, list comparison, repetition counting, and the creation of the new text file.
