Logical XOR function

Training

require_once 'ANN/ANN_Loader.php';

try
{
  $objNetwork = ANN_Network::loadFromFile('xor.dat');
}
catch(Exception $e)
{
  print 'Creating a new one...';
	
  $objNetwork = new ANN_Network;
}

$arrInputs = array(
	array(0, 0),
	array(0, 1),
	array(1, 0),
	array(1, 1)
);

$arrOutputs = array(
	array(0),
	array(1),
	array(1),
	array(0)
);

$objNetwork ->setInputs($arrInputs);

$objNetwork ->setOutputs($arrOutputs);

$objNetwork ->train();

$objNetwork ->saveToFile('xor.dat');

Using trained network

require_once 'ANN/ANN_Loader.php';

try
{
  $network = ANN_Network::loadFromFile('xor.dat');
}
catch(Exception $e)
{
  die('Network not found');
}

$inputs = array(
	array(0, 0),
	array(0, 1),
	array(1, 0),
	array(1, 1)
);

$network->setInputs($inputs);

print_r($network->getOutputs());
