cycle through various POST array variables and types

[AmericanWoman]

I know I remember this from way back when, but I need to find some code that cycles through all the variables of a POST array...and if the variable is, itself, an array, it splits it into its individual values.

For instance, my config screen has a multiple select box, in addition to several regular text boxes, etc. While the text boxes will return a single value, the select box returns an array. I'm hoping to find some simple code to cycle through both types, and output the name/value pairs to a querystring.

Any ideas?
