phpScenario is an object-oriented split testing library written in PHP. It’s designed to do simple A/B testing with as little code as possible, but should also be as powerful as you need it to be.
Default tests can be ran with only a single line of code and results are rendered XML-based (HTML via included XSL stylesheet).
The library supports PDO and Zend Framework DBALs. Also, it has various options for running more customized tests like using identifiers other than PHPSESSID.
Some key features:
- One line testing through smart defaults.
- Support for PDO and Zend Framework DBALs.
- XML-based result renderer (HTML via included XSL stylesheet).
Requirements: PHP
