It's not hard to write a function that does as such without the use of a structure like that, though I can't see it being bad to have-- example: function export_script_vars($var_names) { $result = ""; foreach ($var_names as $var_name) { $result .= '<input type="hidden" name="$var_name" value="${$GLOBALS["$var_name"]}" /><br /> } return $result; } This works provided that you are calling this from the top-level, and if not, you have to export your variables out to the top level with $GLOBALS. It should work, though. Chris
