PHP Safe_mode

Is there a way to turnoff safe_mode?

If not, is there a way to modify temporary file locations and temporary file upload locations? I'm trying to install an application (collectiveaccess.org) that doesn't like safemode because it cant access the temp files because of permissions.

Thanks
Bruce

Can you please post the code of Backend.php (the one around line 171).
