Laravel 5.1 Validation Outside Laravel

First you need to install illuminate/validation by typing this composer require illuminate/validation:5.1.*.

Then, you can use laravel validation like this:

$validatorFactory = new ValidatorFactory;

$validator = $validatorFactory->make($_POST, [
    'username' => 'required|alpha_dash',
    'email' => 'required|email',
    'password' => 'required|min:6',
    'confirm_password' => 'required|same:password'
]);

if ($validator->fails()) {
    // do something with error messages
    $errors = $validator->errors(); // errors collection
    $error_email = $errors->first('email');
    $error_username = $errors->first('username');
    $list_errors = $errors->all('<li>:message</li>');
}

ValidatorFactory.php

<?php

use Illuminate\Validation\Factory;
use Symfony\Component\Translation\Loader\ArrayLoader;
use Symfony\Component\Translation\MessageSelector;
use Symfony\Component\Translation\Translator;

    public function __construct()
    {
        $translator = $this->setupTranslator();
        $this->factory = new Factory($translator);
    }
    
    protected function setupTranslator()
    {
        $translator = new Translator('en', new MessageSelector);
        $translator->addLoader('array', new ArrayLoader());
        $translator->addResource('array', [

Somehow for some reason, the ValidatorFactory.php is not found.
