High Quality Content by WIKIPEDIA articles! 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 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.
