# sebastian/comparator
[](https://github.com/sebastianbergmann/comparator/actions)
[](https://shepherd.dev/github/sebastianbergmann/comparator)
This component provides the functionality to compare PHP values for equality.
## Installation
You can add this library as a local, per-project dependency to your project using [Composer](https://getcomposer.org/):
```
composer require sebastian/comparator
```
If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:
```
composer require --dev sebastian/comparator
```
## Usage
```php
<?php
use SebastianBergmann\Comparator\Factory;
use SebastianBergmann\Comparator\ComparisonFailure;
$date1 = new DateTime('2013-03-29 04:13:35', new DateTimeZone('America/New_York'));
$date2 = new DateTime('2013-03-29 03:13:35', new DateTimeZone('America/Chicago'));
$factory = new Factory;
$comparator = $factory->getComparatorFor($date1, $date2);
try {
$comparator->assertEquals($date1, $date2);
print "Dates match";
} catch (ComparisonFailure $failure) {
print "Dates don't match";
}
```
