I must've been going in a different direction when I made it two functions. Problem reamins: Before exiting the function, I can print the true variable name/value pair. As soon as I exit the function, the same print statement returns "". Is it possible to make the variable variable global? Here's what I know have: function conv_vars($input) { global ${$tmp_var_name}; if (IsSet($input)) { while ($each_array = each($input)) { if (is_array($each_array[1])) { conv_vars($each_array[1]); } else { if (substr($each_array[0],-5) == "_post") { $tmp_var_name = substr($each_array[0],0,-5); ${$tmp_var_name} = $each_array[1]; } } } } }
