 I've been looking at the php manual section on variable 
 variables but I
 don't think i either a) understand it, or b) it isn't what I need.
 
 Here's the coup:
 
 I have a bunch of post vars, lets say $red, $green and $blue
 I want to loop through the post vars and create a variable callled
 $file_red, $file_green and $file_blue

Try this (untested!):

foreach($_POST as $key=$value):
${file_$key} = $value;
endforeach;

Cheers!

Mike

Or you could simply use:

  extract($_POST, EXTR_PREFIX_ALL, 'file_');

That does the same thing much quicker.

   extract($_POST, EXTR_PREFIX_ALL, 'file_');

A little typo, extract() automatically attaches 
a '_' so the third parameter here would be just 
'file'.  

This behavior is unlike import_request_variables() 
and I assume the behavior remains for historical 
reasons.  Kinda odd.

Philip Olson
