php-src/ext/standard/basic_functions.c
Andi Gutmans 2337d110f9 - Added opened_path to php_fopen_wrapper() and the URL fopen wrapper (it's not 
always properly set, it's a TODO for all of us).  This enables us to implement
  true 'use' support.
@- Added support for the 'use' keyword - behaves like 'require', but will not
@  use the same file more than once (Andi & Zeev, Zend library)
