Storring arrays in Sessions

[rrsub]

I must be doing this wrong.

I have this variable which is $cat[$i]['m'] which is different dependent upon whatever the value of $i is.

I want to store this as a session variable which I think I do by

$_SESSION['cat[$i][m]'] = $cat[$i]['m'];

That doesn't work.
$i=2;
echo $_SESSION['cat[$i][m]'];

is different from

echo $_SESSION['cat[2][m]'];

Can someone point me in the right direction?

Have you tried the 'variable variables' feature?

http://www.php.net/variables.variable

I think that's what you are looking for(try [$$i]). Then again, I'm probably totally off. Think I'm getting the flu, a little dizzy

The problem is your use of quotes inside the array refence. Those single quotes tells PHP to store the value in an array element named, literally, "$cat[$i]['m']". It's not storing any kind of array.

You're trying to store a single value of an array in a session variable, but still preserve the array?

You could just store the single value:

$_SESSION['fromcat'] = $cat[$i]['m'];

or just store the entire array, if you're going to need to access multiple values in later scripts.:

$_SESSION['cat'] = $cat;

sleipnir24,

I slept on it and the solution I came up with is the latter of your choices.


Thanks. I kinda felt I was doing it wrong.
