Boolean Validator

This validator can be used to ensure that a given value contains only boolean literals (i.e. true or false).

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 Boolean validator and pass to it the data that you want to validate.

<?php
use Sparta\Validators\Boolean;

$validator = Boolean();

//Assuming that we have a variable called "$isMember"
if(!$validator->isValid($isMember)){ 
    //handle errors
}

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 = [
    'isMember' => 'boolean',
];

//Assuming we have a $data inputs collection that  
//has an element with the key "isMember"
$validation = new Validation($data, $rules);
if(!$validation->isValid()){
    //handle errors
}

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