FAQ
Example:
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 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.

Installation
We recommend installing this package with Composer.
Via composer
In your project root folder, execute
You should now have the files composer.json and composer.lock as well as the directory vendor in your project directory.
You can then require the Composer autoloader from your code
Or, if you already have a composer.json file, then require this package in that file
and update composer.
From Phar
Although we strongly recommend using Composer, we also provide a Phar archive builder that will create a Phar file containing all of the library code.
The phar builder script is in the repository root folder, and can be run using
To use the archive, just require it from your script:
Standard Autoloader
If you want to run the code without using composer's autoloader, and don't want to build the phar, then required the bootstrap.php file from the repository in your code, and this will enable the autoloader for the library.
