how to set/get session info within fcns?

[Anon]

I can't seem to access session variables from within functions. Perhaps someone can suggest what I am doing wrong.

I know this is not the right forum, but the coding forum seems to be broken right now.

Thanks,

Andrew

Example

function set_foo($foo)
{
if(session_is_registered("foo")
$foo="bar";
}

$foo="test";
session_register("foo");
set_foo($foo);
echo $foo;

//when I do this, foo is not set to bar.

The problem is that when you set $foo inside of your function, you are only setting the local variable $foo to "bar", and not the global variable $foo which is the one that is registered. If you did something more like this, it should work:

function set_foo($valueforfoo)
{
global $foo;

if (session_is_registered("foo")
$foo = $valueforfoo;
}

$foo = "test";
session_register("foo");
set_foo("bar");
echo $foo;
