Contributing to PHP-ML

PHP-ML is an open source project. If you'd like to contribute, please read the following text. Before I can merge your Pull-Request here are some guidelines that you need to follow. These guidelines exist not to annoy you, but to keep the code base clean, unified and future proof.


You should only open pull requests against the master branch.

Unit Tests

Please try to add a test for your pull-request. You can run the unit-tests by calling:


Performance Tests

Before first run bootstrap script will download all necessary datasets from public repository php-ai/php-ml-datasets.

Time performance tests:

vendor/bin/phpbench run --report=time

Memory performance tests:

vendor/bin/phpbench run --report=memory


GitHub automatically run your pull request through Travis CI. If you break the tests, I cannot merge your code, so please make sure that your code is working before opening up a Pull-Request.


Please give me time to review your pull requests. I will give my best to review everything as fast as possible, but cannot always live up to my own expectations.
