Schema
======

[](#schema)

[![Build Status](https://camo.githubusercontent.com/e419e48928098f38386f00683c2ba0caf15523e8413f43812ca06f52eae99ede/68747470733a2f2f7472617669732d63692e6f72672f6e6f7274687068702f736368656d612e7376673f6272616e63683d6d6173746572)](https://travis-ci.org/northphp/schema)

A simple schema validation package.

Installation
------------

[](#installation)

```
composer require north/schema

```

Examples
--------

[](#examples)

Basic validation of an array.

```
use North\Schema\Schema;

$schema = new Schema([
    'name' => 'string',
    'age' => 'int',
]);

// validate input against schema.
// returns bool or throws exception.
$schema->valid([
    'name' => 'fredrik',
    'age' => 27,
]);
```

Class validation converts class to array and validates public properties.

```
use North\Schema\Schema;

class User
{
    public $name = '';

    public function __construct($o)
    {
        foreach ($o as $k => $v) {
            $this->$k = $v;
        }
    }
}

$schema = new Schema([
    'name' => 'string',
]);

// validate input against schema.
// returns bool or throws exception.
$schema->valid(
    new User([
        'name' => 'fredrik',
    ]),
);
```

Types
-----

[](#types)

- array
- bool/boolean
- callable
- closure
- function
- implements (implements:INTERFACE)
- int/integer
- iterable
- float
- string
- object
- resources
- type (type:CLASS)

Types can take arguments, for example for implements and type:

```
[
    'person' => 'type:Person',
    'implements' => 'implements:Stringable',
]
```

Custom types
------------

[](#custom-types)

```
$schema->addType('custom_string', function($value) {
    return is_string($value);
});
```

When using extra arguments for types you just takes in more arguments.

```
$schema->addType('type', function ($t, string $expected) {
    return get_class($t) === $expected;
});
```
