Yeah, but it wouldn't read access_log.tmp, which wasn't being written to at the time of loading. I think the whole logs folder is restricted from php access.On Fri, Aug 22, 2008 at 10:13 AM, Ashley Sheridan <ash@xxxxxxxxxxxxxxxxxxxx> wrote:
The log file was in the process of being written to as you were trying to read it. It's a bit like trying to look at a quark. By doing so, you've already affected its position. Although, unlike a quark, you can create a copy of the log file ;)

Yeah, I tried changing the perms, and that didn't work. I originally made
the cron job put the temp copy in the same logs folder, but it refused to
open that. I changed it to put the temp copy in the web folder, and it can
read that. I think apache and/or php may have certain restrictions that keep
them from accessing important system folders.
