Store multiple "identical" arrays in a session - confused about variable/dynamic variables

[eluser]munkeh[/eluser]
Yeah, I found that out when I tried to get the data back out of the session

I was like 'wait a second, how am I supposed to know the session value before I look at the session value?'

So now I have a parts array in the session indexed by unique serial number..

Code:

$parts_array = $this->session->userdata('add_parts');
foreach($parts_array as $part)
{
    // do things to $part['removed_serial_number']
}

.. works just fine, problem solved and it's time for a coffee. Thanks again!
