# Comparator
|
|
|
|
This component provides the functionality to compare PHP values for equality.
|
|
|
|
## Installation
|
|
|
|
To add Comparator as a local, per-project dependency to your project, simply add a dependency on `sebastian/comparator` to your project's `composer.json` file. Here is a minimal example of a `composer.json` file that just defines a dependency on Comparator 1.2:
|
|
|
|
```JSON
|
|
{
|
|
"require": {
|
|
"sebastian/comparator": "~1.2"
|
|
}
|
|
}
|
|
```
|
|
|
|
## 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";
|
|
}
|
|
```
