Registering a variable creates a global instance of the variable, but it does not automatically pull
it into the local scope.
So to set a registered variable within a function:
<?
session_start();
function test( $val ) {
session_register( "somevar" );
// $somevar = $val; //-- This will NOT set the value of the registered somevar, instead it creates
a local, albeit unrelated, instance
$GLOBALS['somevar'] = $val; //This sets the registered $somevar
}
test( "A value" );
?>
