Shell Arguments for PHP CLI

• Version: v1.0.4
• Date: October 17th 2018
• Release notes
• GitHub repository

A convenience class for loading arguments passed through the command line ($argv)

• Autoloads from $argv, or pass in handcrafted array
• Uses the Iterator base class, but adds find() to make looking for, and testing, arguments trivial.
• Support for most common argument formats

Installation

Shell Arguments for PHP CLI is installed via Composer. To install, use composer require pointybeard/shell-args or add "pointybeard/shell-args": "~1.0" to your composer.json file.

Usage

Include pointybeard\ShellArgs\Lib in your scripts then create an instance of ArgumentIterator. It will automatically look for arguments, or you can pass it your own argument string (see below).

Syntax Supported

This library supports the most common argument formats. Specifically -x, --long, /x. It also supports use of = or : as a delimiter. The following are examples of supported argument syntax:

-x
--aa
--database=blah
-d:blah
--d blah
--database-name=blah
/d blah
-u http://www.theproject.com
-y something
-p:\Users\pointybeard\Sites\shellargs\
-p:"\Users\pointybeard\Sites"
-h:local:host
/host=local-host

Examples

<?php
use pointybeard\ShellArgs\Lib;

// Load up the arguments from $argv. By default
// it will ignore the first item, which is the
// script name
$args = new ArgumentIterator();

// Instead of using $argv, send in an array
// of arguments. e.g. emulates "... -i --database blah"
$args = new ArgumentIterator(false, [
    '-i', '--database', 'blah'
]);

// Arguments can an entire string too [Added 1.0.1]
$args = new ArgumentIterator(false, [
    '-i --database blah'
]);

// Iterate over all the arguments
foreach($args as $a){
    printf("%s => %s" . PHP_EOL, $a->name(), $a->value());
}

// Find a specific argument by name
$args->find('i');

// Find also accepts an array of values, returning the first one that is valid
$args->find(['h', 'help', 'usage']);

Running the Test Suite

You can check that all code is passing by running the following command from the shell-args folder:

./vendor/bin/phpunit --bootstrap vendor/autoload.php tests/ArgumentsTest

If you want to run code coverage (e.g. --coverage-html tests/reports/ ...) you'll need an older version of xdebug (for PHP 5.6). To install this, use the following commands:

pecl channel-update pecl.php.net
pecl install xdebug-2.5.5

You'll need enable xdebug.so. Try adding the following to /etc/php/5.6/mods-available

; configuration for php xdebug module
; priority=20
zend_extension=/usr/lib/php/20131226/xdebug.so 

Then enable it with phpenmod xdebug. The above works on Ubuntu, however, paths might be different for other distros.

If you believe you have found a bug, please report it using the GitHub issue tracker, or better yet, fork the library and submit a pull request.
