DocBlox is a documentation generation application for PHP that parses source code and documentation comments to generate documentation. It supports PHP 5.3+ features and has improved performance over similar tools. DocBlox allows incremental parsing to speed up documentation regeneration when files change. Documentation is generated from docblocks in source code files using supported tags. Elements like classes inherit docblock information from their parents. Docblocks can reference other documented elements. Templates and themes customize the output documentation format and styles. Plugins will allow extending DocBlox's functionality in the future.
