Hmmm, this doesn't seem clear in the docs ...
Consider this:
function foo() {
$_SESSION['varname'] = "test";
.....
}
At this point:
- Can I reference $varname inside the function? If so, must it be
declared global first? Or can I only reference it via
$_SESSION['varname']?
- Can I reference it outside the function (as $varname) after the
function returns?
In other words if one creates a variable by adding it to the session
array, does it then become a variable in either the global or (though I
can't quite imagine this) current local scope?
Thanks,
