 New Comment:

realpath_cache is the system that allows php to cache paths to locations of files/directories you
are using to minimize expensive disk lookups. It could possibly greatly improve performance of you
PHP application/site if you use alot of relative file paths PHP has to parse/lookup each time you
reference them.

> Realpath function is using realpath_cache.

While this shouldn't be surprising, I agree that the documentation
of the realpath cache (and also the stat chache) could be
improved.

Description:
------------
Realpath function is using realpath_cache. This is not documented anywhere.


Test script:
---------------
<?php

exec("ln -nsf test1 test");
echo realpath("test") . "\n";
exec("ln -nsf test2 test");
echo realpath("test") . "\n";

Expected result:
----------------
/home/****/realpath/test1
/home/****/realpath/test2

Actual result:
--------------
/home/****/realpath/test1
/home/****/realpath/test1
