Multidimensional $session

[thetuningspoon]

I'm trying to use ProcessWire's $session variable to store multidimensional arrays, like I often do with $_SESSION. I can store multidimensional arrays alright, but if I want to change a variable in one of $session's multidemensional arrays, like so:

$session->myArray['one']['two'] = 'foo';

...I am not able to. Is there any way to do this easily with $session, or am I better off just using php's $_SESSION?

This should work:

$myArray = $session->myArray;
$myArray['one']['two'] = 'foo';
$session->myArray = $myArray;

Ok, that's what I thought. I'll probably stick with $_SESSION since it doesn't require the extra steps.

I think this is similar to this? http://processwire.com/talk/topic/691-wireinput-only-allows-one-dimensional-arrays-why/  $input doesn't do multidimensional arrays either...Advice is to use $_POST, etc..in such cases

PW also uses $_SESSION, so there's no harm in using it. It's not going to break anything if you use both $_SESSION and $session. But one thing to note is that PW keeps $session variables in a namespace within $_SESSION. So while you can use $_SESSION or $session, you can't access the same variables from them, i.e. $_SESSION['first_name'] will not be accessible via $session->first_name, or the other way around.
