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

<?php
use Sparta\Validators\Json;

$validator = Json();

if(!$validator->isValid('{"a":1,"b":2,"c":3,"d":4,"e":5}')){ 
    //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 = [
    'data_load' => 'json',
];

//Assuming that your $data has an element with the key "data_load"
$validation = new Validation($data, $rules);
if(!$validation->isValid()){
    //handle errors
}

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