[RESOLVED] session syntax

jasondavis

echo $_SESSION['info']['auto_id'];
echo $_SESSION['auto_id'];

I just realized I have been using to variations on my site, they both have the same value, is this bad?

It is unnecessary.
If you can call it echo $_SESSION['auto_id']; and not need the ['info'] dimension.

It is a bit like using an array, instead of a simple variable.

$name['person'] = "Harry";
$personname = "Harry"; // better, if possible

If the two variables are being used to store the same data, then if not "bad" it is certainly redundant (which most programmers consider "bad", anyway 🙂 ).

If they are, in fact, being used to store different data and it is obvious to anyone maintaining the code what the difference is between them, then no problem. If it's not clear what the difference is between them, then you might want to use more descriptive array index names.

thanks for the info =)

What would be bad is if you get confused about which one you're supposed to be looking at at any given point. Or, if they really are supposed to be the same, letting them drift out of sync.
