Duplicate index refs (key

Duplicate index refs (key names) in this instance are fine as they are different/separate arrays.
Otherwise PHP would hit an error creating them, not deleting them.

As you both mentioned, echoing out at every stage is the way to find errors, and I had done this (always do) I just didn't do it on another block of code that was also accessing the session.
(truth be known I thought I'd commented it out while testing this block )

So as often is the case, it was that other piece of code that was causing the issue to the session, not the above delete loop.
And in the end was simply my numbtiness for not having commented out some untested code.

So all is well now, cheers.

I'm just getting vibes that

I'm just getting vibes that having the same keys (make,colour) in two different arrays is somehow related to your problem...

Have you tested it out with all unique keys?

What is messed up about the array once you've done an unset on it?
Are you missing data? Is there too much data?

Cheers,

yeah as I showed above printing the array, it's storing it perfectly, there's just something wrong with the removal. I thought perhaps something to do with the unsetting within a loop and change of the session/array index within the loop, although it's not the array the loop is using that I change...

So I would think your removal code may work if you add the additional level - because for one array, it is essentially two-dimensional, the first two keys are always the same, only the third one changes...

$_SESSION['test']['car']['make']="ford";
$_SESSION['test']['car']['colour']="red";

['test'] is the session name, albeit the session is an array, ['car'] is a key in the session array and the value for ['car'] is another array where ['make'] is one key and ford is the value, ['colour'] is another key and red is the value.

$rem_key would be "car" or "bike" and unset($_SESSION['test'][$rem_key]); should remove that full array from the session

Maybe inspecting the cookie at each step will provide a clue.

Isn't it actually a 3-dimensional array? ['test']['car']['make']

$_SESSION['test']['car']['make']="ford";
$_SESSION['test']['car']['colour']="red";
