PHP-ArgumentParser

Command line arguments parser in PHP, inspired by argparse for Python.

I was doing a school project for PHP and I was not really satisfied with php getopt. So I wrote this very simple parser based on Python's argparse. As I said it is really basic but maybe someone will find it useful :)

Example:

$ php your_program --source=filename -f

Array 
(
    [source] => filename
    [f] => 1
)

To achieve this all you need to do is:

include 'ArgParser.php';

$message = "USAGE: php your_program [--source filename] [-f]";
$parser = new ArgParser($usage=$message);

$parser->add_argument('source', $help='a help message', $action='get_val');
$parser->add_argument('f', $help='a help message', $action='store_true');
$parser->add_argument("help", $help="print help message", $action='print_help');

$args = $parser->parse();

And that's it !

Possible actions are:

get_val = this means the argument expects a value (--source filename)
store_true = store 1 when argument is found
store_false = store 0 when argument is found
print_help = should be applied only for the --help argument, prints usage and all help messages

Parser accepts arguments in all these formats:

--source filename
--source=filename
-source filename
source filename

Limitations:

Parser does not accept multiple arguments written together:
-rtf would be interpreted as one argument rtf, not 3 arguments -r, -t, -f
