Make getopt ignore first argument

Question

I’m creating a PHP CLI, and wanted to run something like this

php console.php comando -a foo -b bar -d

But with the function getopt I can’t get past the comando if not the Buga function and do not receive any of the other arguments. I need to set a default parameter as -c:

php console.php -c comando -a foo -b bar -d

Does anyone know any method to "parse" the arguments by ignoring the first?

PS: I also need to get the first argument, to know which command should be executed.

Code: ^{(github link)}

public function run() {

  $command = $this->getCommand();

  if (is_null($command)) return FALSE;
  $optcll = $command->getOptionCollection();
  $opts = $optcll->dump();

  // LINHA QUE PEGO OS ARGUMENTOS DO COMANDO
  $args = getopt($opts['options'], $opts['longopts']);

  return $command->execute($this, $args);

}

I don’t know if it satisfies your needs, but there is a library docopt for PHP.

With it, all you have to do is write the documentation of your commands and the library will handle the entries, handing you an object with the information provided by the user. For example, considering your example, we could do:

<?php

$doc = <<<DOC
Descrição da aplicação.

Usage:
  console.php comando [-a A] [-b B] [-d]
  console.php (-h | --help)
  console.php --version

Options:
  -h --help     Exibe a mensagem de ajuda.
  --version     Exibe a versão.
  -a A          Valor de A.
  -b B          Valor de B.
  -d            Define como D.
DOC;

require('vendor/autoload.php');

$args = Docopt::handle($doc, array('version'=>'0.1.0'));

foreach ($args as $k => $v)
{
    echo $k.': '.json_encode($v).PHP_EOL;
}

Thus, you can display the help message with the command:

$ php console.php -h

Descrição da aplicação.

Usage:
  console.php comando [-a A] [-b B] [-d]
  console.php (-h | --help)
  console.php --version

Options:
  -h --help     Exibe a mensagem de ajuda.
  --version     Exibe a versão.
  -a A          Valor de A.
  -b B          Valor de B.
  -d            Define como D.

Display version with command:

$ php console.php --version

0.1.0

Or execute the commands provided in Usage:

$ php console.php comando

comando: true
-a: null
-b: null
-d: false
--help: false
--version: false

As I defined the options as optional and did not inform them, they were defined as null those who possess value, such as -a and -b, and how false those who are flags, as -d. When you enter the figures, you are:

$ php console.php comando -a foo -b bar -d

comando: true
-a: "foo"
-b: "bar"
-d: true
--help: false
--version: false
