PHP-Genny

Overview

PHP-Genny is a semantic code generation library. It provides a fluid builder interface around php-parser's own code generation API's and, perhaps more interestingly, provides API's for intelligently generating large graphs of interdependent objects., _(*1)

Installation

composer require jdwil/php-genny
