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.
Chase's Twiddle algorithm for returning all m-combinations of an array of size n.
More info about the original algorithm can be found here and a C
implementation can be found here.
Unlike other recursive algorithms for building combinations this one allows you to build combinations iteratively and
thus stop at any point when you've had enough without having to build all of the combinations first.
This package provides both a PHP \Generator and a standard method for retrieving
Requirements
PHP7.4 & PHP8
How to use
The following code will initialize a new Twiddle instance for building 2-combinations of a set of size 10.
After initializing the instance you can run the algorithm on all arrays of size n (10 in the example).
Local development
Run docker-compose up -d to run the docker environment. You can then SSH into one of the PHP containers (one has php7.4 and the other one has php8.0) to run composer, tests etc.: docker-compose exec php7 bash or docker-compose exec php8 bash
The codebase is going to be mounted onto /app inside the containers.
Composer command for our command line client (download client)This client runs in each environment. You don't need a specific PHP version etc. The first 20 API calls are free.Standard composer command
