First ideas for interfaces for console-commands

CommandInterface.php

<?php

interface CommandInterface
{
  public function execute(InputInterface $input, OutputInterface $output);
}

InputInterface.php

<?php

interface InputInterface
{
  public function getArgument($argName) : mixed;
  
  public function getArguments() : array;
  
  public function getOption($argName) : mixed;
  
  public function getOptions() : array;
  
  public function hasArgument($argName) : boolean;
  
  public function hasOption($argName) : boolean;
}

OutputInterface.php

<?php

interface OutputInterface
{
  public function getVerbosity() : int;
  
  /**
   * @param string|array $message
   */
  public function write($message, bool $newline = false, int $options = 0) : void;
  
  /**
   * @param string|array $message
   */
  public function writeln($message, int $options = 0) : void;
}
