Well, the only thing that comes from the client side is GET, POST, or COOKIE
data. All the browsers should handle GET and POST data the same, so I doubt
that's it. Is the work computer your on accepting cookies? Are values from
cookies or sessions used anywhere in the SQL in question?

Subject: [PHP] Strange intermittant errors

> Hi,
> I am developing a website in PHP that stores all its information in a
> database. The webserver is a FreeBSD box running Apache with pretty much

> is competant at setting this sort of box up, so I am confident its all

> Now, the site works fine 100% of the time when I visit it from home (Amiga
> 4000, with any of these browsers: AWeb, IBrowse and Voyager), but when I
> visit from my work computer (IE 6, Windows 98 SE, going through an NT4

> after a refresh or two! They happen on pretty much ANY page that accesses

> It even occurs on pages where the mysql query is a hardcoded string, so it

> Now, 2 or 3 friends have visited the site with linux boxes and windows,

> This is the type of error that I get from my work machine:
> Warning: mysql_num_rows(): supplied argument is not a valid MySQL result
> resource in /home/httpd/www.videobrewery.com/shownews.php on line 40
> So it appears the original mysql_query() is failing. What could be causing
> that from the client end?!
