[newbie] Array form values.

I have a form that is an extended version of this: <form> <input type="text" name="email[1]"> <input type="text" name="email[2]"> <input type="text" name="email[3]"> </form> Unfortunately, the email[1] part was generated using a variable in a loop. I have no idea how many of these fields there really will be each time this is done. I then need to turn around and, while processing the form, extract the values for each field in another loop. Trying to do echo $email[$i] doesn't seem to work, though. Is my entire logical approach wrong? Could it be something wrong with syntax? Is it not possible to use a variable as the inner part of an array like that? ooo, or best one to answer: does someone have a snippet of code doing what I want to do here, that I could learn from?
