CLI issue: Changing STDERR

Hey.. seeing as there is not way specified in the docs that I can find, I thought I'd email this list as there may be an undocumented way of doing it. On Linux: I'm converting some bash scripts to php.. in the bash scripts I sometimes do at the very top: " exec 2>/path/filename " Which changes where stderr goes because it closes and reopens file descriptor 2 I've played around and around with things with some php cli scripts, but cannot do it. Is there a way of changing the actual process's file descriptor 2 to something else. (or any fd for that matter) Thanks, Davy
