1. Type in your first name, last name and click submit. The PHP script takes all the name value pairs in the form and pushes it into the global associative array $_POST
  2. Now type in
    " disabled="1
    in first name or last name, and submit. After submitting, notice that the form input first name has been disabled. Why does that happen? Suggest a way to fix this problem.
  3. Notice that in $_POST, nothing is appended to the URL query. How would this be better than $_GET?
