PHP Diff Class
--------------

[](#php-diff-class)

Introduction
------------

[](#introduction)

A comprehensive library for generating differences between two hashable objects (strings or arrays). Generated differences can be rendered in all of the standard formats including:

- Unified
- Context
- Inline HTML
- Side by Side HTML

The logic behind the core of the diff engine (ie, the sequence matcher) is primarily based on the Python difflib package. The reason for doing so is primarily because of its high degree of accuracy.

Example Use
-----------

[](#example-use)

A quick usage example can be found in the example/ directory and under example.php.

More complete documentation will be available shortly.
