This is the code:
$app->post(’/photo’, function (Request $request, Response $response) {
$directory = $this->get('upload_directory');
echo 'hi ';
$uploadedFiles = $request->getUploadedFiles();
$uploadedFile = $uploadedFiles['picture'];
if($uploadedFile->getError() === UPLOAD_ERR_OK) {

$response->write('uploaded ' . $filename . '<br/>');
}
});
function moveUploadedFile($directory, UploadedFile $uploadedFile){
$extension = pathinfo($uploadedFile->getClientFilename(),
PATHINFO_EXTENSION);
$basename = bin2hex(random_bytes(8));
$filename = sprintf(’%s.%0.8s’, $basename, $extension);
$uploadedFile->moveTo($directory . DIRECTORY_SEPARATOR . $filename);
return $filename;
