I moved to our new server which is using 5.3.2. I'm getting a segmentation
fault error on certain ODBC queries I run. For some reason when I ask for
particular columns from the database table I get the error. The error is
Program received signal SIGSEGV, Segmentation fault.
0x00007ffff530df1a in memcpy () from /lib/libc.so.6
Does anyone have any ideas why this is happening?
Thanks!
Floyd

There is something fishy about libc, php or the odbc driver you are
using on the new server. Try recompiling php, odbc. You wouldn't be able
to compile libc, unless you're using a source based distribution like
gentoo.

Hi,
I need some help with my html/php, restricted access script.
The purpose with this script is to let users login to a members area; some with
admin permission, some with newbe permission and some with advanced
permissions. The permissions are pre-defined in the MySQL-DB with a
use_level-field in the user-table.
The different user-groups should have access to the following content:
admin - permissions to everything (for now the same as advanced)
advanced - lecture 1 and lecture 2
newbe - only lecture 1
The problem with this script is that it does not redirect the different user
groups to their repective index-pages, please help me to detect why!

you didn't set the $message
for example here that you mentioned:
<div class="message">You have successfuly been logged in. You can now access
the advanced area.<br />
change it to $message="You have successfuly been logged in. You can now
access the advanced area";
hope it will help.
