        ]
    ],
    
];

In module.config.php add the following:

use Mecanik\SanitiserX\SanitiserXManager;
use Mecanik\SanitiserX\Service\SanitiserXManagerFactory;

'service_manager' => [
				'factories' => [
				    SanitiserXManager::class => SanitiserXManagerFactory::class,
				],
],

Load the module in PROJECT\config\modules.config.php:

'Mecanik\SanitiserX',

Inject the service into your controller:

use Mecanik\SanitiserX\SanitiserXManager;

// This is just for example, MyController is your controller
class MyControllerFactory implements FactoryInterface
{
	public function __invoke(ContainerInterface $container, $requestedName, array $options = null)
	{
		$security = $container->get(SanitiserXManager::class);
    
		// Instantiate the controller and inject dependencies
		return new MyController($security);
	}
}

And use the functions in your controller:

use Mecanik\SanitiserX\SanitiserXManager;

// This is just for example, MyController is your controller
class MyController extends AbstractActionController
{   
    /**
     * Mecanik's Sanitiser Modules
     * @var SanitiserXManager
     */
    private $security;
    
    /**
     * Constructor. Its purpose is to inject dependencies into the controller.
     */
    public function __construct($security)
    {
    	$this->security = $security;
   	 }
   	 
   	 public function someAction()
   	 {
   	 	$this->security->SanitiseInput($_GET['username'], 1);
   	 }
}

Current filter options


// Cross-Site Scripting
// FILTER_TYPE_XSS = 1
$this->security->SanitiseInput($_GET['username'], 1);   

//Cross-Site Request Forgery
//FILTER_TYPE_CSRF = 2

$this->security->SanitiseInput($_GET['username'], 2);   

//SQL Injection
//FILTER_TYPE_SQLi = 3

$this->security->SanitiseInput($_GET['username'], 3);   

//Remote File Inclusion
//FILTER_TYPE_RFI = 4

$this->security->SanitiseInput($_GET['username'], 4);   

//Local File Inclusion
//FILTER_TYPE_LFI = 5

$this->security->SanitiseInput($_GET['username'], 5);   

//All filters possible
//FILTER_TYPE_ALL = 6

$this->security->SanitiseInput($_GET['username'], 6);
