PhpDocumentor

phpDocumentor is an open-source documentation generator written in PHP. It automatically parses PHP source code and produces readable API and source code documentation, based on PHPDoc-formatted comments and the structure of the source code itself. It supports documentation of both object-oriented and procedural code. phpDocumentor runs at the command line to create documentation in HTML format. It has support for linking between documentation, incorporating user level documents like tutorials, and creation of highlighted source code with cross referencing to PHP general documentation.
