<?php
$storage = new \\Upload\\Storage\\FileSystem('/path/to/directory');
$file = new \\Upload\\File('foo', $storage);

// Optionally you can rename the file on upload
$new_filename = uniqid();
$file->setName($new_filename);

// Validate file upload
// MimeType List => http://www.iana.org/assignments/media-types/media-types.xhtml
$file->addValidations(array(
    // Ensure file is of type "image/png"
    new \\Upload\\Validation\\Mimetype('image/png'),

    //You can also add multi mimetype validation
    //new \\Upload\\Validation\\Mimetype(array('image/png', 'image/gif'))

    // Ensure file is no larger than 5M (use "B", "K", M", or "G")
    new \\Upload\\Validation\\Size('5M')
));

// Access data about the file that has been uploaded
$data = array(
    'name'       => $file->getNameWithExtension(),
    'extension'  => $file->getExtension(),
    'mime'       => $file->getMimetype(),
    'size'       => $file->getSize(),
    'md5'        => $file->getMd5(),
    'dimensions' => $file->getDimensions()
);

// Try to upload file
try {
    // Success!
    $file->upload();
} catch (\\Exception $e) {
    // Fail!
    $errors = $file->getErrors();
}
