Sessions and Functions

[Anon]

Im trying to implement sessions into my php code.. the main problem im having is.. I cant see any registered variables in functions.. here is an example

I have two files.. index.html and test1.php
test1.php includes functions..

index.html has this at the very top..

<?php
session_start();

session_register('Check');
$Check = "Checking";
?>

then a few lines down in the html code its this..

<?php require("test1.php"); ?>
<?php Test(); ?>

---

now in the test1.php file this is what I have

<?php
function Test() {
session_register('Check');
echo $Check;
}

?>

this is the problem.. when I do an echo.. I dont get anything.. $Check should contain a string "Checking" but doesnt print anything.. anyone got any ideas??

Two points:
1. You don't have to 'session_register()' a variable if it's already (supposed to be) in the session. You only register vars when you put them into the session for the first time.

2. Functions have their own scope. That means that variables that were declared outside the function (and all session vars are declared outside the functions) are not available inside the functions unless you pass them as parameters or you import them using the 'global' statement.
