Download the PHP package nekman/luhn-algorithm without Composer

On this page you can find all versions of the php package nekman/luhn-algorithm. It is possible to download/install these versions without Composer. Possible dependencies are resolved automatically.


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.

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?

The Number class is a container class that holds the actual number and the check digit. It does no validation nor does it calculate the check digit. It exists to clearly separate the number from the check digit and to define when the check digit exists or not. To simplify the process of validating a number you can use the named constructor Number::fromString() like this:

Alternatively, if you want to calculate the checksum or check digit for a number:
