Thanks for your help. I do not have any more info on the error; that is all
the visitor to my site provided. But I am not sure what more useful detail
there could be; it was a fatal error as I described; the script aborted on
line 82, the IF statement.
However, it might be useful to know that my host computer is running version
3.0.12 of PHP3 on a Unix server.
As for the code, I am not sure what more context would be helpful; the error
message indicated a failure on the function strtoupper() in that statement.
The statement is within a validation routine. I am running a series of tests
on $xmbrcode, a cookie variable; each test is independent.
You are correct in that creating a new variable instead of substringing it 3
times would be more efficient. However I cannot see how this would make a
significant difference.
I am baffled as to why PHP would fail on a valid statement, and fail only
for that user. Since the code is executed on the host computer, I do not see
how a slow connection would have any effect on it. I can see why extremely
heavy traffic on my host computer might cause a timeout, but not for one
user only, and not always on the same statement. By the time the HTML code
is sent to the user, I thought that the execution of PHP was done. In any
event, today, when this error was reported to me, has been one of the
slowest days of the year at my site.
Maybe I just baffle easily
Thanks for your help.
