hide some form information without changing from GET to POST
<p>I have an array of ids and an array of corresponding values on a form.  The user chooses the value on the screen but I am using GET on my form to get the ids.  The problem is I need to convert the key back into the value on the second php page, except that the GET function did not send the value along with the id.  I do not want to send the value over the url and I do not wish to change the URL as it is now (or, by extension, change from GET to POST to hide the value).  </p>

<p>Basically, what is the best way to make this conversion on the second php page having only sent the key over the url and not having the array as a variable on the second page?  I read something about super globals but I was not sure if that was the right way to go.  </p>

<p>Any help would be appreciated. Thanks.</p>
