Answer 1

Hey Kirill, let me explain, print_r($_GET) was supposed to dump the $_GET array content onto screen, in order that we can observe its content, and verify whether the value we want was there.

But if you're doing this on Code Playground, unfortunately you can't, the form needs to be submitted before we can see the values in $_GET array.

Yet, Code Playground doesn't support form submission, that is why you only see "Array ()" in the output, because there is nothing in $_GET until form is submitted.

When I said empty string for the form 'action' attribute, I actually meant that it should be written like this:

<form method="GET" action="">

√ Alternative:
If you have PC/Laptop you can install XAMPP (https://www.apachefriends.org) with which you have web server, database server and PHP ready to play with. Or if you are on Android phone/tablet, you can search Google Play Store for some app that serve the same purpose (contains web server, PHP and MySQL or MariaDB).

Answer 2

If you are submitting the form data to the same file you can omit the 'action' attribute (set it as empty string). Also try to do

print_r($_GET);

Just to see if there was any data sent in. Let me know how it goes ...

P.S. FYI, In case you didn't know, SoloLearn Code Playground does not support form submission test.
