Assigning to self. Talked to philip yesterday; may replace current setup with a modified PhD IDE plugin.

There are MANY functions not listed in the function index.

All the magic methods
All the aliases.
The whole class::method() vs prefix_function() (OOP vs Proc) issue - I think 
both need to be present in the index.

Could missing lcfirst be due to the wrong source code "proto comment"? See bug 52380.

Yes. The phpdoc/trunk/doc-base/funclist.txt, funcindex.xml and funcsummary.txt are 
all built by examining the source using scripts in phpdoc/trunk/doc-base/script.

As the prototypes in the C code don't need to be accurate (most are, but as we can 
see not all), there needs to be a cleanup of them and some consideration to a 
standard approach for the -> and :: issue.

For now I added lcfirst to the function list TOC. dtajchreber@, if the setup should be changed it would be more of a PhD thing so lets keep it there :)

This bug has been fixed in SVN. Since the websites are not directly
updated from the SVN server, the fix might need some time to spread
across the globe to all mirror sites, including PHP.net itself.

Thank you for the report, and for helping us make PHP.net better.

This page is now (and have been a while) generated from the PhD index, which 
solved this problem
