Description:
------------
When running APC, if a script uses the __FILE__ magic constant to determine the 
full directory name of where the script is running from, it will continue to get 
the same directory, even if the directory of the script is renamed. 

Example:
Place the test script in a directory named "mydir1" and access the script with a 
browser.  Then, in the directory above mydir1, type "mv mydir1 mydir2" to rename 
the directory.  If you access the script now, it will not be found.  If you then 
change the url to reference the script in the proper directory of mydir2, it 
will 
be found, however, it will report the __FILE__ magic constant to be mydir1.

This can cause issues if one uses __FILE__ when including other scripts, as they 
won't be found after the directory is renamed, until the APC cache is cleared or 
the script's timestamp is modified.

I tried running this on a server without APC and it behaved as expected.


Test script:
---------------
<?php
echo ' hello '.date('r').'<br/>';
echo ' magic constant __FILE__  '.__FILE__."<br/>";
?>


Expected result:
----------------
I expect it to output the correct full path to the script

Actual result:
--------------
It outputs the path of the script as it was before renaming the directory.
