phpDocumentor is an application that is capable of analyzing your PHP source code and DocBlock comments to generate a complete set of API Documentation.

Inspired by phpDocumentor 1 and JavaDoc it continues to innovate and is up to date with the latest technologies and PHP language features.

Features: phpDocumentor supports the following:

• PHP 5.3 compatible, full support for Namespaces, Closures and more is provided
• Shows any tag, some tags add additional functionality to phpDocumentor (such as @link)
• Processing speed, Zend Framework experienced a significant reduction in processing time compared to phpDocumentor 1
• Low memory usage, peak memory usage for small projects is less than 20MB, medium projects 40MB and large frameworks 100MB
• Incremental parsing, if you kept the Structure file from a previous run you get an additional performance boost of up to 80% on top of the mentioned processing speed above
• Easy template building, if you want to make a branding you only have to call 1 task and edit 3 files
• Command-line compatibility with phpDocumentor 1, phpDocumentor 2 is an application in its own right but the basic phpDocumentor 1 arguments, such as --directory, --file and --target, have been adopted
• Two-step process, phpDocumentor first generates a cache with your application structure before creating the output. If you'd like you can use that to power your own tools or formatters!
