If a <refentry> should not emit versioning information, what should I do?

  • Add the role=“noversion” to its <refentry>
  • Example: <refentry xml:id="reserved.variables.argc" xmlns="http://docbook.org/ns/docbook" xmlns:xlink="http://www.w3.org/1999/xlink" role="noversion//">

How do I add a link to a method?

  • Use <methodname>Class::Method</methodname>
  • Note that the case does not matter when adding a link.

I'm about to document a new PHP extension... how should I start?

  • Use the script found within phpdoc/doc-base/scripts/docgen/*
  • Example: $ php docgen.php -h
  • Example: $ php docgen.php -e simplexml -o outdir
  • It creates the skeletons that you edit then commit

I documented an extension but it's not building. Why?

  • Likely because it has not yet been added to doc-base/manual.xml.in
  • So, add the book to the appropriate reference location there. Open file for examples.
  • Or, configure.php is failing... the error should help

I want to contribute to the PHP Manual, how?

How do I build and/or test the manual locally?

  • Use phpdoc/configure.php to validate and then phd to build
  • To validate en: $ php configure.php
  • To validate fr: $ php configure.php --with-lang=fr (Change fr to your given language code)
  • To build: $ phd -d .manual.xml
  • Note: Building is not required, all you must do is check the diff and be sure it validates

Running configure.php ends up Segfaulting, what is up?

  • There are bugs with certain versions of libxml that cause this, so hacks exist to get around it
  • To execute the hack, pass in: $ php configure.php --disable-segfault-error
  • Note: This disables some error checking and beautification but raw errors will be shown
  • Note: Usually the problem is a major XML syntax issue

In the changelog, which order do the PHP versions go?

  • Newest PHP versions go above the older ones

A feature became available in PHP X.Y.Z, how do I document that?

  • Version information for functions is stored inside versions.xml within each extension: phpdoc/en/extname/version.xml
  • Changes to functions, like added parameters, are documented within changelogs for each page
  • Example Text: Feature X has been available since PHP X.Y.Z
  • TODO: Research other ways, and the best way, to write this text (including dealing with code examples)

Why does everyone care so much about whitespace?

  • See the following article: whitespace
  • XML is one space, PHP example code is four, and max width is ~78 characters
  • Exceptions: <refpurpose> is on one line, ...

A parameter is optional, how is it documented?

  • Like normal, except methodparam receives the choice=“opt” attribute, and the <initializer> tag is used to signify the default value.
  • Example: <methodparam choice="opt"><type>bool</type><parameter>httponly</parameter><initializer>false</initializer></methodparam>

Do I need to edit these entities* files?

  • No, these are auto-generated by the configure process
  • Examples: entities/file-entities.ent and en/reference/foo/entities.bar.xml
  • Also, do not commit them

How do I create a patch?

  • In the command-line, go to the SVN directory:
  • cd /path/to/phpdoc/svn
  • To diff the entire repository: svn diff
  • To diff a single file: svn diff foo.xml
  • Consider piping the diff to a file, so: svn diff foo.xml > mypatch.txt

How do I apply a patch?

  • Assuming the file with the patch is named apatch.txt
  • Go to the directory with the files to be patched
  • And run this command: patch -p0 < apatch.txt

Is there an online editor?
