[SOLVED]PHP playground not working OR what???

Question

I started learning PHP as of recent in SoloLearn. I noticed today that I can't make a simple Calculator in PHP display answers when I click on the submit button. Instead it opens my phone browser automatically and ends up not displaying anything. How can I fix this...
Here is the code:

Answer 1

Form submission is not supported on SoloLearn Code Playground, solution would be to use JavaScript instead, or install XAMPP ( https://www.apachefriends.org ) if you're using laptop/PC, or find an app that simulates something similar in the store (Play or Apple) for your mobile device.
