|
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";
|
|
}
|
|
```
