Jennifer,
I could be wrong but this is what I think you have;
When the session_register is executed the session contents are partially
updated.
Your first test actually executed the session_register that posted the
variable with 0 string length, because the variable had not yet been
initialized (the bad return is the only indication of this).
Your test that the variable is registered would seem to suggest this.
You then changed the variable value and failed to register this new value.
The second page found the only value you registered (the uninitialized
variable with zero length) and displayed that.
You can identify what actually happened by viewing the session file contents
after your two pages are displayed.
hope this helps,
Warren Vail

This is all what I thought, but I am still having problems and I
don't have a clue what I am missing. Here's an example that I
have been paying with for testing.
page1.php contains
<?php
session_start();
echo "session id is ".session_id()."<br>\n";
if (session_register("testing")) {
echo "session_register worked.<br>\n";
}
else {
echo "session_register did not work<br>\n";
}
if (session_is_registered("testing")) {
echo "testing is a registered variable<br>\n";
}
else {
echo "testing is not a registered variable<br>\n";
}
$testing = "Let's see if this works.";
?>
<a href="page2.php?<?=SID?>">Go to next page.</a>
The output of the above page, gives me
session id is e35c2893382e28a14fa0455302edb06e
session_register did not work
testing is a registered variable
Go to next page.
and page2.php contains
<?php
session_start();
echo "session id is ".session_id()."<br>\n";
echo "Testing: $testing<br>\n";
?>
The output of page2 gives me
session id is e35c2893382e28a14fa0455302edb06e
Testing:
I am totally confused. First off, why isn't it registering the
variable? There is a file named e35c2893382e28a14fa0455302edb06e
in my /tmp directory, but it is empty.
Second, if it isn't registering the variable then why is
session_is_registered("testing") returning true?
