input file only accepts xlsx?

[bobnino]

I think the code should accept input files other then xlsx and should include input of arrays or some kind of metrics for training.

require('vendor/autoload.php');

$c45 = new Algorithm\C45();
$input = new Algorithm\C45\DataInput;
$data = array(
	array(
		"OUTLOOK" => "Sunny",
		"TEMPERATURE" => "Hot",
		"HUMIDITY" => "High",
		"WINDY" => "False",
		"PLAY" => "No"
	),
	array(
		"OUTLOOK" => "Sunny",
		"TEMPERATURE" => "Hot",
		"HUMIDITY" => "High",
		"WINDY" => "True",
		"PLAY" => "No"
	),
	array(
		"OUTLOOK" => "Cloudy",
		"TEMPERATURE" => "Hot",
		"HUMIDITY" => "High",
		"WINDY" => "False",
		"PLAY" => "Yes"
	),
	array(

// Initialize Data
$input->setData($data); // Set data from array
$input->setAttributes(array('OUTLOOK', 'TEMPERATURE', 'HUMIDITY', 'WINDY', 'PLAY')); // Set attributes of data

// Initialize C4.5
$c45->c45 = $input; // Set input data

$initialize = $c45->initialize(); // initialize

// Build Output
$buildTree = $initialize->buildTree(); // Build tree
$arrayTree = $buildTree->toArray(); // Set to array
$stringTree = $buildTree->toString(); // Set to string

echo "<pre>";
print_r ($arrayTree);
echo "</pre>";

echo $stringTree;

Excellent, thank you.

I just couldn’t find it in the examples.
