Bug description:fopen uses stale data on symlinks - opens old file instead
Description:
------------
After opening a symlink, PHP will always use the original link location,
even if the link is externally modified during script execution.
Test script:
---------------
<?php
file_put_contents("linkOrig", "old data");
file_put_contents("linkNew", "new data");
//create the link
symlink("linkOrig", "link");
//`ln -s linkOrig link`;//this also works
file_get_contents("link");//open it and read it (caches the link data)
//simulate another program altering it
`ln -fs linkNew link`;
echo file_get_contents("link");
Expected result:
----------------
new data
Actual result:
--------------
old data
