If you are using the array forget about session_register.

Could you post a little code? That will make this easier to solve.

do you get any output on the second page if you do this?
?php
session_start();
print 'pre';
print_r($_SESSION);
print '/pre';
if ( isset($_SESSION['logged_in'])){
echo Welcome...;
}else{
header(location: user.php?action=9);

you only want to check to see if there is at least one digit?
If that is true, this should work:
if(preg_match('/\d/',$password)) {
echo 'password ok';
}

That does not work either... I can not make the statement fail!!!
I have tried
$password = 123456;
and
$password = abcdef;
I have change the if statement to what is below and past in all letters
and
it still works?

The IP's (for example 192.168.1.1) are all in a single field.
[/snip]
If it is a possiblity, I would store each IP in its own row, with a
column in that row being some kind of flag, like: is_issued as a logical
column.
Can you change you db layout or is it set in stone?

Hi Matt
Before sending the result set, the mssql extension stores the entire
result set into memory. However, PHP limits the amount of memory that
can be allocated by a script to 8MB. So, the query will fail if the
result set is larger than 8MB. You can change this value in php.ini

So if a user hits submit on a webpage, the transaction under the hood
completes, no matter if the user hits cancel or his browser dies or
whatever. (Not sure how to even test this condition, but I know it

Actually whether the script runs through to completion depends on the

WHAT DOESN'T HAPPEN is that the query_string values DO NOT trump the
