php warnings in Windows port

Post #1 of 3 (479 views)

Hi!

Windows me, Xitami, PHP 4.3.1, wikipedia scripts: source forge dump 29.03

Trying to find out why the submit does not return correctly, I stumbled on
the cgi error log file of Xitami.

I have no idea if there is a relation with the issue, but there are quite a
number of disturbing warnings (they appear in case of opening a page and
modifying it).

This can be because of Xitami, or a wrong php version, or Windows, or
because it is running locally, or of installation errors...

However, if this can explain my submit pb, let me know.

Change the error reporting level in your php configuration to not include
'notices'. These are just telling us that the web server didn't report
certain values from the http headers, so the magic array doesn't contain
anything at those indices. We already know that because it will have
returned NULL instead of a useful string. So, not very helpful. :)

Now that's the kind of error message I hate: "unexpected error"! Almost as
good as "unknown error"...

That's in wfUnix2Timestamp(). I think the only thing that uses this is the
last-modified check in OutputPage::checkLastModified(). You might try
putting some debug checks into that function to check on the input to the
function (make sure strtotime() is working and that the server variable
comes through right).

Also, note that a lot of the time calls may break (returning the wrong
time) if your timezone setting is not at GMT/UTC. I haven't tested that
case.

These are all because it already spit out some error messages, and don't
indicate any real problems.

Again, change the error reporting level (see above) to make these go away.

See above.

Thanks a lot for the help!

$_SERVER("HTTP_IS_MODIFIED_SINCE") is most of the time not set. When I got
a non null value it was:

Tue, 28 Jan 2003 11:24:44 GMT; length=8031

(no idea what the date/time refers to! Possibly in relation with the Upload
file special page...)

When given to strtotime, this returns -1, and date() is no happy.

Removing the part after the semi-column makes strtotime returning a 10
digit string.

I'll patch temporarily my outputpage, adding code to remove anything after
a semi-column...

Any idea about what is happening??
