PHP I: Comparison

Introduction

The Comparable interface defines the getComparisonTo method, which determines the sort order of instances of the implementing type.

The Equalable interface defines the isEqualTo & isNotEqualTo methods, which determines the equality of instances of the implementing type.

Motivation

PHP doesn't have built-in interfaces for object comparison. Inspired by:

• Java Comparable interface
• .NET IComparable interface
• .NET IEquatable interface
• Ruby Comparable module
