Answer 1

piyush singh
<?php
define("MSG", " Hi SoloLearners!");?>
<?=MSG;?>

Answer 2

The problem has to do with the case. You used msg instead of MSG, which was defined.
change msg to MSG and you'll be good to go.

Answer 3

piyush singh I think it might be because the case insensitive declarations weren't deprecated the time Sololearn published the lesson. The default of constants is false, so you don't have to provide the true parameter.

Answer 4
