using strings as variable names

[Ian_Wright]

I have a configuration file containg a list of variable names e.g. $first_name, $second_name, etc. I want a script to repsond to an HTML form by reading this file so that it knows the names of the variables in that from. In other words I need to use the string "$first_name" as a variable name. Any ideas?

Thanks,
Ian
