PHP Validation Library

Simple and lightweight standalone PHP library for validating data.

Usage

<?php

use SGP\Validation\Validator;

$input = [
    'name' => 'Svilen Popov',
    'comment' => 'This a comment',
    'users' => [
        [
            'age' => 20,
            'username' => 'username1'
        ],
        [
            'age' => 16,
            'username' => 'username2'
        ]
    ]
];

$rules = [
    'name' => 'required',
    'comment' => 'required|min:20',
    'users.*.age' => 'required|min:18'
];

$messages = [
    'comment.min' => 'Your comment should have at least 20 chars.'
];

$validator = Validator::make($input, $rules, $messages);

$errors = $validator->errors()->all();

foreach ($errors as $error) {
    echo $error . PHP_EOL;
}

and the above example will output:

Your comment should have at least 20 chars.
The users.1.age minimum is 18
