2. Different usage of Arrayer.

Arrayer can process not only $`_`POST array, you can use any string array as well.

/**
 * Example to use $an_array array:
 */

$array = new Arrayer($an_array);


/**
 * Also you can use $_GET array.
 */

$get = new Arrayer($_GET);

/**
 * Or you may add expected variables (with default values if applicable).
 */

$expected_vars = array(
	'username' => '',
	'email' => '',
	'age' => '',
	'password' => '',
	'repassword' => '',
	'country' => 'RU',
);

$post = new Arrayer($_POST, $expected_vars);
