5.14. @package

The @package tag is used to categorize Structural Elements into logical subdivisions.

5.14.1. Syntax

@package [level 1]\[level 2]\[etc.]

5.14.2. Description

The @package tag can be used as a counterpart or supplement to Namespaces. Namespaces provide a functional subdivision of Structural Elements where the @package tag can provide a logical subdivision in which way the elements can be grouped with a different hierarchy.

If, across the board, both logical and functional subdivisions are equal is it NOT RECOMMENDED to use the @package tag, to prevent maintenance overhead.

Each level in the logical hierarchy MUST separated with a backslash (\) to be familiar to Namespaces. A hierarchy MAY be of endless depth but it is RECOMMENDED to keep the depth at less or equal than six levels.

Note: DocBlox also allows the underscore (_) and dot (.) as separator for compatibility with existing projects. Despite this the backslash is RECOMMENDED as separator.

Please note that the @package applies to different Structural Elements depending where it is defined.

1. If the @package is defined in the file-level DocBlock then it only applies to the following elements in the applicable file:
   • global functions
   • global constants
   • global variables
   • requires and includes
2. If the @package is defined in a namespace-level or class-level DocBlock then the package applies to that namespace, class or interface and their contained elements. This means that a function which is contained in a namespace with the @package tag assumes that package.

This tag MUST NOT occur more than once in a PHPDoc.

5.14.3. Effects in DocBlox

Structural Elements tagged with the @package tag are grouped and organized in their own sidebar section.
