This library allows to communicate with Robust or OpenSimulator instance with rest console enabled.

It can be used inside a PHP project, or as a command-line client for OpenSimulator grids.

Available commands can be found here: http://opensimulator.org/wiki/Server_Commands

Requirements

PHP 8.2 or newer, with the curl, libxml and simplexml extensions.

On Debian and Ubuntu: sudo apt install php-cli php-curl php-xml.

Prerequisites

Remote connection must be enabled in your Robust .ini file.

Do not leave default values!. You should never need to type username and password manually, so you can safely generate long random strings.

You must choose a specific port, not already used by another service. It is good practice to limit access to this port to authorized IP addresses only in your firewall settings.

[Network]
  ConsoleUser = arandomgeneratedstring
  ConsolePass = anotherrandomgeneratedstring
  ConsolePort = 8009
  ; choose a port not already used by another service

Building

Requires PHP with phar.readonly disabled (already the case for CLI by default on most systems).

php -d phar.readonly=off dev/build-phar.php

The executable is created at bin/opensim-rest-cli.

Command-line client

Download the executable from this repository, make sure opensim-rest-cli is executable and move it to /usr/local/bin/.

chmod +x /path/to/opensim-rest-cli
sudo mv /path/to/opensim-rest-cli /usr/local/bin/opensim-rest-cli

You can run commands like

opensim-rest-cli /path/to/Robust.ini show info
opensim-rest-cli /path/to/Robust.ini show regions

If you save the credentials in ~/.opensim-rest-cli.ini, you can skip the Robust.ini argument.

Other ways to give the commands and reach the console:

opensim-rest-cli --ini /path/to/OpenSim.ini -- show regions   # one command
opensim-rest-cli --ini /path/to/Robust.ini --host 127.0.0.1 -- show info   # from the machine itself, instead of BaseURL
echo "show info" | opensim-rest-cli --ini /path/to/Robust.ini -   # the lines of the standard input, one command or answer each
opensim-rest-cli --ini /path/to/Robust.ini --repl   # a prompt, as the console of the instance
OPENSIM_REST_PASSWORD=secret opensim-rest-cli --url http://host:9300 --user admin -- show info

The client waits for the console to be ready again after each line (--wait SECONDS, 5 by default), so a command that asks a question gets its answer from the next line. It exits with 0 when done, 1 when the console cannot be reached or opened, 2 on a wrong usage; the errors go to the standard error.

opensim-rest-cli show info
opensim-rest-cli show regions

PHP class

Method 1: Install with composer (recommended for standalone projects)

composer require magicoli/opensim-rest-php

Then in your PHP code:

require_once 'vendor/autoload.php';

$session = opensim_rest_session( array( ‘uri’ => "yourgrid.org:8009", ‘ConsoleUser’ => ‘yourConsoleUsername’, ‘ConsolePass’ => ‘yourConsolePassword’, ) );

if ( is_opensim_rest_error($session) ) { error_log( "OpenSim_Rest error: " . $session->getMessage() ); } else { $responseLines = $session->sendCommand($command); }

Return value: an array containing the line(s) of response or a PHP Error

Method 2: Git Submodule + sparse (recommended for integrated projects)

Setting sparse config is critical to avoid executables being accessible on public website.

From your project directory:

git submodule add https://github.com/magicoli/opensim-rest-php.git opensim-rest
cd opensim-rest
git config core.sparseCheckout true

echo ‘‘ > $(git rev-parse –git-dir)/info/sparse-checkout echo ‘!bin/‘ >> $(git rev-parse –git-dir)/info/sparse-checkout echo ‘!dev/*’ >> $(git rev-parse –git-dir)/info/sparse-checkout echo ‘!opensim-rest-cli.php’ >> $(git rev-parse –git-dir)/info/sparse-checkout echo ‘!composer.lock’ >> $(git rev-parse –git-dir)/info/sparse-checkout

git read-tree -m -u HEAD

This will give you only the files you need:

opensim-rest/
├── class-rest.php
├── composer.json
├── LICENSE
└── README.md

Then in your PHP code:

require_once dirname(__FILE__) . '/opensim-rest/class-rest.php';
// Same usage as above

Method 3: Manual download (not recommended)

You won’t get updates…

Download class-rest.php file in your project or
