README

This library compares two values for equality.

If you need to add your own rules for comparing specific values, you can extend the library with your own comparison strategies.

Features

• Simple equality comparison (== or ===)
• Strategy interface for your own comparison rules

Installation

composer require scheb/comparator

How to use

$comparator = new \Scheb\Comparator\Comparator(true); // Type-sensive equal (===)
$comparator->isEqual(0, "0"); // Returns false
$comparator->isEqual(0, ""); // Returns false
$comparator->isEqual(0, 0); // Returns true
$comparator->isEqual(0, "foo"); // Returns false

$comparator = new \Scheb\Comparator\Comparator(false); // Type-insensive equal (==)
$comparator->isEqual(0, "0"); // Returns true
$comparator->isEqual(0, ""); // Returns true
$comparator->isEqual(0, 0); // Returns true
$comparator->isEqual(0, "foo"); // Returns false

How to extend

To add your own comparison strategy, implement Scheb\Comparator\ValueComparisonStrategyInterface.

Then, add an instance of that class via the constructor argument $customComparisonStrategies of Scheb\Comparator\Comparator.

Custom comparison strategies take preference over default ones.
