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.

Informations about the package php-ssh

PHP SSH

Build Status (develop)

Provides an object-oriented wrapper for the php ssh2 extension. This is based on the work of Antoine Hérault.

Requirements

You need PHP version 7.1+ with the SSH2 extension.

Installation

The best way to add the library to your project is using composer.

$ composer require luka/php-ssh:^2.0

Usage

Configuration of the connection

To establish an SSH connection, you must first define its configuration. For that, create a Configuration instance with all the needed parameters.

The available configuration classes are:

Both connection configuration and public/private key authentication can be obtained from a ssh config file such as ~/.ssh/config

Create a session

The session is the central access point to the SSH functionality provided by the library.

Authentication

The authentication classes allow you to authenticate over a SSH session. When you define an authentication for a session, it will authenticate on connection.

The available authentication are:

Authentication from Ssh\OpenSSH\ConfigFile

If you use an ssh config file you can load your authentication and configuration from it as follows:

This will pick up the username, and your public and private keys from your config file Host and Identity declarations.

This simple snippet only works if the User declaration is also present, and the private key does not require a pass phrase. If any of this is not the case you have to pass the missing values to the createAuthentication() method.

Subsystems

Once you are authenticated over a SSH session, you can use the subsystems.

Sftp

You can easily access the sftp subsystem of a session using the getSftp() method:

See the Ssh\Sftp class for more details on the available methods.

Publickey

The session also provides the getPublickey() method to access the publickey subsystem:

The Public-Key subsystem allows you to provide multiple public keys to use for authentication. See the Ssh\Publickey class for more details on the available methods.

Exec

The session provides the getExec() method to access the exec subsystem

See the Ssh\Exec class for more details.
