This is a behavior I have not found documented, in fact the books I have
read indicated that this would not be the case...
given the script (with session.save_handler = files):
<?php
function reg() {
$test = 13;
session_register("test");
echo "in reg(), test=<$test><br>";
}
session_start();
reg();
echo "test=<$test><br>";
?>
The output is:
in reg(), test=<13>
test=<>
I was quite surprised, but at least now I know why my code isn't working. I
assume that $test is going out of scope after the function reg() exits. BUT,
isn't registering a variable as a session variable supposed to give it
"superglobal" status? I thought so. Can someone give me the 'official'
explanation of this behavior?
Many thanks,
Richard
