				phpDocumentor Frequently Asked Questions

################################################################################

Introduction

################################################################################

Before we start with questions and their answers, make sure to read the

documentation *thoroughly* found at http://www.phpdoc.org/manual.php.  The

complexity of phpDocumentor can be a bit impenetrable until you understand the

logic behind it.

If you have read the documentation thoroughly, and have read this FAQ and you

are still lost, please go directly to the bug database at

http://sourceforge.net/tracker/?group_id=11194&atid=111194 and read through the

open bugs.  If you don't find the solution to your problem (or proof that it

at least is not your fault), then go to the help forum and post a help message

at http://sourceforge.net/forum/forum.php?forum_id=35065.

Installation

 Q: There is no package.xml in the release, where is it?

Documentation Errors

 Q: I keep getting an illegal package tag error for the first DocBlock in a file,

    isn't this a page-level DocBlock?

 Q: I keep getting a warning that there is no @package tag in file xxx.php, but

    there is a @package tag in the class definition, doesn't this apply to the

    file?

Installation

################################################################################

Q: There is no package.xml in the release, where is it?

A: this problem occurs when one does the faulty steps of:

$ tar xvf PhpDocumentor-1.3.1.tgz

$ pear install package.xml

   instead, the user should simply run:

$ pear install PhpDocumentor-1.3.1.tgz

   or, if the zlib extension is not enabled:

$ gunzip PhpDocumentor-1.3.1.tgz

$ pear install PhpDocumentor-1.3.1.tar

Q: I keep getting an illegal package tag error for the first DocBlock in a file,

   isn't this a page-level DocBlock?

---

---[[UPDATE]]

---VERSION 1.2.2 has a different page-level docblock recognition algorithm

---Now, the first docblock in a file is a page-level docblock if it contains

---a @package tag.

---

A: Please read the documentation very carefully.  A page-level DocBlock does

   occur at the start of a file, but the first DocBlock is not always a

   page-level DocBlock!  Why is this?  Very often, you will want to document

   the entire page, or describe it (this page contains functions for blah), and

   also document the first item in a page separately.  An example:

   <?php

   /**

   * This file contains all foobar functions and defines

   * @package mypackage

   */

   /**

   * controls parsing of bar information

   */

   define('parse_bar',true);

   ?>

   The page has its own information, and the define has its own information.

   An example of what not to do:

   <?php

   /**

   * This file contains all foobar functions and defines

   * @package mypackage

   */

   define('parse_bar',true);

   ?>

   Here, the DocBlock belongs to the define and not to the page!  phpDocumentor

   can successfully parse this DocBlock, but it will apply the comment to the

   documentation of define('parse_bar',true); and not to the page.  Therefore,

   it warns you that your @package tag will be ignored because defines may not

   contain a @package tag.

Q: I keep getting a warning that there is no @package tag in file xxx.php, but

   there is a @package tag in the class definition, doesn't this apply to the

   file?

A: No.  This example does not have a page-level DocBlock:

   <?php

   /**

   * This class is in package mypackage

   * @package mypackage

   */

   class in_mypackage {...}

   ?>

   phpDocumentor therefore assumes the page-level package is the same as the

   class package, mypackage.  This is fine in most cases, but if multiple

   classes are in the same file with different packages, as in:

   <?php

   /**

   * This class is in package mypackage

   * @package mypackage

   */

   class in_mypackage {...}

   /**

   * This class is in package anotherpackage

   * @package anotherpackage

   */

   class in_anotherpackage {...}

   ?>

   There is no way to determine which package the page should belong to, and

   phpDocumentor will automatically put it in the default package.  This can

   cause incredible headaches debugging, and so we have added a warning in the

   1.2.0 series that informs you if the package is inferred by phpDocumentor.

   To fix this warning, simply place a page-level DocBlock with a @package tag

   like:

   <?php

   /**

   * This file contains two packages

   * @package filepackage

   */

   /**

   * This class is in package mypackage

   * @package mypackage

   */

   class in_mypackage {...}

   /**

   * This class is in package anotherpackage

   * @package anotherpackage

   */

   class in_anotherpackage {...}

   ?>

Q: Can you implement the @example tag inline so that I can put PHP source code

   examples directly in DocBlocks?

A: This is implemented using the HTML <code></code> tags as in:

   /**

    * Short description

    *

    * Start of long description, here is a code example:

    * <code>

    *  $my_phpcode = "easy to explain";

    * </code>

    * More text

    * <code>

    *  define('morecode',true);

    * </code>

    */

Crash/Segfaults

Q: phpDocumentor crashes if I use __FUNCTION__!!!

A: This is caused by a known bug in all PHP versions prior to 4.3.2.  It was

   fixed in PHP 4.3.2RC1, you must upgrade to PHP 4.3.2 if you use __FUNCTION__

   in code that you wish to document (sorry!) or apply the bugfix patch to the

   tokenizer extension and recompile php (see the php.internals archive at

   php.net for help)
