Hi i have encountered a strange problem to which i am not able to
figure out!.

I have two separate databases, 1st stores user details, 2nd stores
messages, they are on different ip address and both servers are
synchronized by load balancer. The php script works fine except for
this unique situation where the script is not able to display username
and email address in textboxes, but it does display user number and
associated message.

My question is why is php refusing to display user name and email when
it is stored successfully in the database and yet it displays user
number from 1st database and message from 2nd database.

I have tested the script with other username and email and it works
fine! But it doesn't work with this particular user!

Are there any bugs in PHP in which this situation can occur or is it
something else?

All your help is appreciated.

Thanks
undbund

Leaving aside the question of why you are using two databases, instead
of two tables this sounds like either a coding or html problem.

Either way, unless you have a good reason, I'd consider putting related
data in the same database.

Hey thanks for your reply, what do you thinks could go wrong in terms
of coding or html, as I have mentioned, this is the only bit of data
that is giving problems, the script works flawlessly with 99.99% of the
data in the database. I have examined the data in the databases, they
are just like any other bits of data. No fancy characters, etc!!

Thanks

Well then at this point I would use a debugger to track the problem
down. I use Xdebug and tswebeditor to step thru the code line by line in
problem blocks of code. Not sure if you are using a debugger. You could
look at a free one here: http://tswebeditor.at.tf

Hey thanks for all your help and contributions. I have found out that
there was a problem with the load balancer, it was not synchronizing
the databases properply.

Thanks for all your help

Does your code depend on PHP sessions or cookies? You said you've
got two servers on two different IP addresses. Cookies set by one
IP may not be sent back to the other IP, depending on domain and
browser settings. If this is the problem, it's not a PHP bug, it's
a browser security feature.

Or maybe I'm completely off base here. You didn't show any code.
