Variable name as a variable?

I need to store a variable name as a variable. Note quite a C-style pointer, but a way to access one variable who's name is stored in another variable. As part of a spam-control measure, a certain public-facing form will have dummy rotating text fields and a hidden field that will describe which text field should be considered, like this: input type="text" name="text_1" input type="text" name="text_2" input type="text" name="text_3" input type="hidden" name="real_field" value="text_2" As this will be a very general-purpose tool, a switch statement on the hidden field's value would not be appropriate here. Naturally, the situation will be much more complex and this is a non-obfuscated generalization of the HTML side of things which should describe the problem that I need to solve on the server side. Thanks in advance for any ideas. -- Dotan Cohen http://what-is-what.com http://gibberish.co.il
