[JJR512]

Let's say I have an array:

$array = "50,60,70,80,90";

And I want to take each element of the array and do something with it. The specific something is a mathmatical operation; let's say I want to subtract 10 from each number. Then, after subracting 10 from each number, I want so put all the results back into a new array. The new array would look like "40,50,60,70,80".

How do I write this?

I know to start with something like:

$exploded_array = explode(",",$array)

But where do I go from there? (And in the explode(), does $array need to be enclosed in quotes or not?)

You can also use foreach, like this:

Block Disabled:      (Update License Status)

But I think the first method is more elegant.

Chen I forget but why do you add a & to the front of a variable in certain cases?
