Register Vars with Vars

[phreak]

Ok, this may be a little confusing. But how would I go about registering an unknown amount of session variables? For instance, I have a form created from information in a text file. Now, if that file changes, the amount of fields that are displayed and used are changed.

How would I go about registering all of those fields in a session? For example, would I do it like this:

session_register($var1, $var2, $var3...);

or like this:

session_register($$var1, $$var2, $$var3...);

or neither?

I want the variable to be registered and to maintain it's value.

Thanks for the help.

Create the form from your text file.

When the user completes the form and submits it, the values in the fields are going to go into either $POST or $GET arrays.

Process the relevant array to get the keys - these will be your variable names to be registered

foreach ($_GET as $key=>$value) {
    $_SESSION[$key] = $value;
}
