```

> **New to composer?**
>
> Composer is a dependency manager for PHP. Composer can install this package from the [packagist.org registry](https://packagist.org/packages/einlinuus/php-validator). Once installed, you'll find a `vendor` directory in your project.
>
> You can import all required files by importing the `autoload.php` file created by composer: `require_once __DIR__ . "/vendor/autoload.php";` With the autoload-file included in your project, you now have access to all classes and functions provided by this package.

Usage
-----

[](#usage)

Simply create a new instance of the Validator class and pass the input data to the constructor.

Next, chain the validation methods inside a try-catch block. If any of the validation methods fail, a ValidatorException will be thrown.

After the validation methods, you can get the output data by calling the get() method. The output data is your input data transformed by the transformation methods. If no transformation methods are used, the output data will be the same as the input data.

```
$input = "hello world";

$v = new Validator($input);
try {
    $v->isString("Input must be a string")
        ->isLowercase("Input must be lowercase")
        ->min(3, "Input must be at least 3 characters long")
        ->max(12, "Input must be at most 10 characters long");
} catch (ValidatorException $e) {
    die("Invalid: " . $e->getMessage());
}

$validated = $v->get();
var_dump($validated); // string(11) "hello world"
```

You can find more examples in the `examples` folder.
