FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:

If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.

Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
To use Composer is sometimes complicated. Especially for beginners.
Composer needs much resources. Sometimes they are not available on a simple webspace.
If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Please rate this library. Is it a good library?

Informations about the package rserve-php

Rserve-php

php5 client for Rserve http://www.rforge.net/Rserve/ (a TCP/IP server for R statistical software)

Changes from 1.0 version

All classes are declared under Sentiweb\Rserve namespace allowing PSR-4 autoloading
Parsers are now individualized into classes
A Parser instance can be directly used as second argument of evalString() to replace default parser (see example)

Tests

You can run tests using phpunit

Several tests need to have a running Rserve server (not handled by this library). To configure the test to use a server you have to configure the connection using environment vars or by creating a file in tests/config.php and defining constants (a sample file is available in tests/config.php.sample). Expected vars (in env or as constant in tests/config.php)

RSERVE_HOST : hostname or IP of the Rserve server (e.g. 'localhost' or 127.0.0.1 for local server).
RSERVE_PORT : port number, if value is '0' or 'unix', the HOST is expected to be a unix socket path.
RSERVE_USER : username if the Rserve server is expecting authentication, skip or leave empty if not
RSERVE_PASS : password if the Rserve server is expecting authentication, skip or leave empty if not

RSERVE_HOST is required to be defined (either env or in config.php) to run the connection aware tests, if not these tests will be skipped.

Credential-free tests

launch your credential-free Rserve instance
- Can be done with docker run -d -p 6311:6311 wnagele/rserve
if installed with composer: composer test
otherwise, run with phpunit

Login tests: This test suite require a credential-protected Rserve instance to be running (not provided by this library) and the credentials (username and password to be configured as described above)

Installation

Using without composer : include src/autoload.php in your project

Using with composer:

run composer require cturbelin/rserve-php:2.0.x-dev
add require __DIR__.'/../vendor/autoload.php'; to your project

Some usage example are provided in example directory

Parsers

Results provided by R could be handled using several parsers

NativeArray Translates R structure into php simple arrays. It is useful to get simple values from R
Wrapped array Using NativeArray with parameters array("wrapper"=>true) in contructor return object with attributes of R objects. The result object can be used as an array and provides methods to access R object attributes
Debug Translates R response to structure useful for debugging
REXP Translates R response into REXP classes

Async Mode

Several functions allow to use connection in async mode

getSocket() to get the socket an set some options
setAsync() allow to set the async mode
getResults($parser) : get and parse the results after a call to evalString() in async mode
