Affirm is a simple, no-frills assertion/validation package written for PHP 5.4+. It is a PHP port of [is.js](http://arasatasaygin.github.io/is.js/).

It is quite similar to [Assert](https://github.com/beberlei/assert), and aims to match it.

Install
-------

[](#install)

Via Composer

```
$ composer require hassankhan/affirm
```

Usage
-----

[](#usage)

First instantiate the class:

```
$affirm = new Affirm\Affirm()
```

You can use either `Affirm::is()` or `Affirm::are()` to pass in any values:

```
$affirm->is(25, 50, 75);
$affirm->are(25, 50, 75);
```

Once all values have been passed in, you can use a modifier. By default, Affirm will only return `true` if all values pass the test, you can change this like so:

```
$affirm->is(25, 50, 75)->any();
```

Then add your test:

```
$affirm->is(25, 50, 75)->any()->odd();
```

You can also use Affirm as a static class:

```
Affirm\Proxy::is(25, 50, 75)->any()->odd();
```

Please read the API documentation for a full list of available methods.
