Schema

A simple schema validation package.

Installation

composer require north/schema

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

• 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

$schema->addType('custom_string', function($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;
});
