PHP simple maths quiz program

Question

I\'m trying to create a maths quiz page. The first page needs to generate a question shown as a header, that asks the user what two random numbers are multiplied together. Then

Answer 1

You must have the header() code before any output, especially that echo statement.

Answer 2

Apart from sending the headers before you output something, i think your form action is wrong, it should be

action="<?php echo $_SERVER['PHP_SELF']; ?>"

You are sending the POST via FILE protocol, it won't be processed by Web Server/PHP.

And also, you are not POSTing "first" and "second" fields.
