Question

I have built an empty associative array whos keynames refer to submitted post data. I can capture the postdata just fine, but I run into trouble trying to instantiate varia

Answer 1

The solution is change

$key = stripslashes(filter_input(INPUT_POST, $key));

to

$$key = stripslashes(filter_input(INPUT_POST, $key));
