Validation library for PHP 5.6+ / PHP 7 / HHVM inspired by Joi from Hapi.

Installation

The recommended way to install the library is through Composer

composer require bartosz-maciaszek/validation

Examples

Validation with the library is straightforward. You can validate primitives like this:

<?php

use Validation\Validation as V;

V::validate('foobar', V::string(), function($err, $output) {
    if ($err) {
        echo 'Validation failed: ' . $err;
        exit;
    }
    
    echo $output; // 'foobar'
});

You can also chain other assertions:

V::validate('user@example.com', V::string()->email(), function($err, $output) {
    // ...
});

The library also supports transformations:

V::validate('FooBar', V::string()->lowercase(), function($err, $output) {
    // $output equals 'foobar'!
});

Wanna something more complex? Let's try to validate an array!

$input = [
    'username' => 'foobar',
    'password' => 'secret123',
    'birthyear' => 1980,
    'email' => 'foobar@example.com',
    'sex' => 'male'
];

$schema = V::arr()->keys([
    'username' => V::string()->alphanum()->min(3)->max(30),
    'password' => V::string()->regex('/[a-z-A-Z0-9]{3,30}/'),
    'birthyear' => V::number()->integer()->min(1900)->max(2013),
    'email' => V::string()->email(),
    'sex' => V::string()->valid('male', 'female')
]);

V::validate($input, $schema, function ($err, $output) {
    // $err === null -> valid!
});
