How to print form inputs on same page using php in SOLOLEARN APP.

Question

I'm unable to print inputs collected by a form on same page after the form section. I've used action attribute with both values i.e. "$_SERVER['PHP_SELF']" and "link of the post code".
In php I'm using if statement with condition "isset($_POST['submitBtn']);"

Answer 1

It means we can't use this app for php projects.
