Hi guys,
I'll answer this and the previous mail.
First, thanks for the insight.
1. There is such a function as "mysql" whose arguments are
mysql("database","query",[resource id])
very useful as it avoids having to call mysql_connect_db()
As for printing the query, I had done that, and everything was fine. I have
however, found the problem!
(sorry about the waste of bandwidth, but maybe someone will avoid making the
same mistake).
The problem was not related to variable scope, but rather because the
variable "1234" had some HTML formatting added to it somewhere in the
script.
The problem, evidently, is that echoing the variable didn't show the html
formatting (it was something like "<font color=black>" in an obvious way!
I wish there were a php debugger.
Again, thanks for the suggestions,
Martin
