There is no global() function in PHP. There is a global keyword. It is like return or continue. It is not a function. Some keywords are accessible with URL shortcuts. It might be a good idea to let global be accessed this way.

Note to the doc guys: possible to fix this by using id="language.keyword.global" and id="language.keyword.static" in the XML files.

I thought I fixed this here:
http://cvs.php.net/diff.php/phpdoc/en/language/variables.xml?r1=1.67&r2=1.68

Why doesn't the following pick this up?
<sect2 id="language.variables.scope.global">

This is related to bug #16234

Erm, the URL shortcuts and the PHP function list search only find nodes having a file named after the name of the keyword/function/control structure, etc. So modifying the ID would not be enough. As sect2s are not put onto their own pages, these need to be sect1s to get recognized by any of the quicref tools we have.

Also 'variables.scope.' is not a searched prefix, thought it can be added if need be. But still only file names are searched for, so if the file name does not contain the searched keyword, it will not be found. Since the documentation is not reindexed to make these keywords be more easy to find, the current solution is for speed reasons.

Goba, would this solve it?

     <emphasis>static</emphasis> variable.  A static variable exists

I wouldn't feel write changing the sect2 ids but maybe we have to?

No, Philip, the file is named after the sect2 id.

I don't see a way how to solve this in the documentation. There are files only for sect1s.

The 404 handler does not allow linking to #anchors so as a  second best option both the static and global keywords are now redirected to /language.variables.scope.php
