This component provides the functionality to compare PHP values for equality.


You can add this library as a local, per-project dependency to your project using Composer:

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


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";
