$HTTP_SESSION_VARS only gets populated when you load another page. Or
refresh the current one. To use your example again...
<?php
function reg() {
$test = 13;
session_register("test");
echo "in reg(), test=<$test><br>";
}
global $HTTP_SESSION_VARS;
session_start();
$test = 12;
reg();
if (session_is_registered("test")) {
$tt = $HTTP_SESSION_VARS["test"];
echo "session variable test=<$tt><br>";
}
else
echo "You really don't know what you're doing, do you?<br>";
?>
Run this script, and it will give the output
in reg(), test=<13>
session variable test=<>
But...
Refresh the page, and you should see:
in reg(), test=<13>
session variable test=<12>
Because $HTTP_SESSION_VARS gets populated. Its something to do with HTTP
headers I think - can't remember exactly why, but I know what happens.

Subject: RE: [PHP] Session variable scope - surprise!
OK, but then how do you explain:
<?php
function reg() {
$test = 13;
session_register("test");
echo "in reg(), test=<$test><br>";
}
global $HTTP_SESSION_VARS;
session_start();
reg();
if (session_is_registered("test")) {
$tt = $HTTP_SESSION_VARS["test"];
echo "session variable test=<$tt><br>";
}
else
echo "You really don't know what you're doing, do you?<br>";
?>
This still gives me the output:
in reg(), test=<13>
session variable test=<>
Aaargh!
