phpspec/php-diff v1.1.3

The phpspec/php-diff is a comprehensive library designed for generating differences between two hashable objects. These object could either be strings or arrays. This library is capable of rendering generated differences in several standard formats including Unified, Context, Inline HTML, and Side by Side HTML. It's built with a core logic that is primarily based on the Python difflib package which is renowned for its high level of accuracy. This makes it an invaluable tool for developers who need to compare different versions of code or content.

The phpspec/php-diff library is conveniently used within your PHP code. Although the readme doesn't directly provide a code usage example, it does mention that a quick usage example can be found in the 'example/' directory and under 'example.php.' Based on typical usage of differences libraries, you would first need to install the package via Composer. While the exact usage might vary depending on your exact requirements, it typically involves creating an instance of the diff class and then passing the two objects you wish to compare into the appropriate function.

// First, include the Diff class
require_once 'path/to/php-diff/Diff.php';

// Then, define the two strings or arrays you wish to compare
$oldVersion = 'Your old version';
$newVersion = 'Your new version';

// Create the diff instance
$diff = new Diff($oldVersion, $newVersion);

// Generate the difference
$diffOutput = $diff->render();

The $diffOutput will now hold the generated differences between the two versions.

The comprehensive documentation for the phpspec/php-diff library isn't provided within the readme, rather it's indicated to be available shortly. As of this update, the most immediate source of information on using the library including any specialized functions or parameters, or how to interpret the output, would likely be found by inspecting the library's source code, located in its GitHub repository. More specifically, details on utilization could presumably be referenced within the 'example.php' file mentioned in the readme. It's prudent to regularly check the official GitHub repository, https://github.com/phpspec/php-diff.git for any updates or additional information on the library's usage and documentation.
