Copy current php page with Values

[Corin]

I have a dynamically created .php file containing user input text and an uploaded .jpg file, called newpage.php. I want to make a copy of this file with a unique id (that's the easy part) and save it to a temp directory (easy too) when the user clicks a button - this is so the user can view their personal page at a later date. Problem is when I open the copied file all the previoulsy input values are missing of course. So my question is what is the best way for me to make a copy, but to also send the global values as a permanent fixture in the new copy too. My copy line so far is

<?php copy("/home/mydomain/public_html/$PHP_SELF", "/home/fmydomain/public_html/temp_files/test.php"); ?>

The newpage.php is opened by a form method POST, with values such as firstname, lastname, picture.jpg. These are the values I'd like to send to the copy test.php but as static values

try this:
exec("cp /home/mydomain/public_html".$_SERVER["PHP_SELF"]." /home/fmydomain/public_html/temp_files/test.php");

No luck with that one either. It saves the current page as before, but does not save the previously input values and image. Instead it saves the page with my default image and data.
