Collection of helpful classes to use when working on the command line (cli).


This library is installed via Composer. To install, use composer require pointybeard/php-cli-lib or add "pointybeard/php-cli-lib": "~1.1" to your composer.json file.

And run composer to update your dependencies:

$ curl -s http://getcomposer.org/installer | php
$ php composer.phar update


This library is broken into 3 distinct components: Message, Prompt, and Argument. They can be used as needed, although they do rely on each other internally.


use CLILib\Message;

## Display a message to STDOUT
(new Message)
    ->message("This is my message")
    ->dateFormat('G:i:s > ')
    ->foreground("light green")


use CLILib\Prompt;
use CLILib\Message;

// Most basic usage
$name = Prompt::display(
    "Please enter your name"
## > Please enter your name:
## >

// Asking for a password
$password = Prompt::display(
    "Please enter your password", Prompt::FLAG_SILENT
## > Please enter your password:
## >

// Providing a Message object and default value
$message = (new Message)
    ->message("Enter database user name")
    ->foreground("light green")
$databaseUserName = Prompt::display(
    $message, null, "root",
## > Enter database user name [root]:
## >

// Using a validator to check the input
$user = Prompt::display(
    "Enter your user name", null, null, function($input){
        if(strlen(trim($input)) == 0) {
            (new Message
                ->message("Error: You must enter a user name!")
            return false;
        return true;
## > Enter your user name:
## >
## > Error: You must enter a user name!
## > Enter your user name:
## >

Argument & Argument/Iterator

Include CLILib\Argument in your scripts then create an instance of Argument\Iterator. 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:

--d blah
/d blah
-u http://www.theproject.com
-y something


use CLILib\Argument;

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

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

// Arguments can an entire string too [Added 1.0.1]
$args = new Argument\Iterator(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

// 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 to install xdebug:

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


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.
