How to install to your project

composer require smoren/validator

Usage

use Smoren\Validator\Factories\Value;
use Smoren\Validator\Exceptions\ValidationError;

$rule = Value::container()
    ->array()
    ->hasAttribute('id', Value::integer()->positive())
    ->hasAttribute('probability', Value::float()->between(0, 1))
    ->hasAttribute('vectors', Value::container()->array()->allValuesAre(
        Value::container()
            ->array()
            ->lengthIs(Value::integer()->equal(2))
            ->allValuesAre(Value::integer())
    ));

$validInput = [
    'id' => 13,
    'probability' => 0.92,
    'vectors' => [[1, 2], [3, 4], [5, 6]],
];

try {
    $rule->validate($validInput);
} catch (ValidationError $e) {
    // Input is valid so this block is unreachable.
}

$invalidInput = [
    'id' => '13',
    'probability' => 1.92,
    'vectors' => [[1, 2.1], [3, 4], [5, 6]],
];

try {
    $rule->validate($invalidInput);
} catch (ValidationError $e) {
    // Input is invalid so we catch the exception.
    print_r($e->getViolatedRestrictions());
