PHPDoc is an adaptation of Javadoc for the PHP programming language. It is a formal standard for commenting PHP code. It allows external document generators like phpDocumentor to generate documentation of APIs and helps some IDEs such as Zend Studio, NetBeans, JetBrains PhpStorm, ActiveState Komodo Edit and IDE, PHPEdit and Aptana Studio to interpret variable types and other ambiguities in the loosely typed language and to provide improved code completion, type hinting and debugging.
PHPDoc supports documentation of both object-oriented and procedural code.
PHPDoc is not currently maintained; the last release was December 3, 2000. There are some up-to-date alternatives, though, such as phpDocumentor and Doxygen.
