Usage

There are two different ways in which all Sparta validators can be used. See below examples for more explanations:

Example #1:

You can simply instantiate the Odd validator and pass to it the data that you want to validate.

<?php
use Sparta\Validators\Odd;

$validator = Odd();
if(!$validator->isValid(1)){
    foreach($validator->errors as $error){
        echo $error;
    }
}

Example #2:

You can build your validation rules and pass it to the Validation object to handle as shown below:

<?php
use Sparta\Validation;

$rules = [
    'odd_number' => 'odd',
];

$validation = new Validation($data, $rules);
if(!$validation->isValid()){
    //handle erros
}

In case of validation failure, error messages can be retrieved using the getErrors method.
