Maybe you want to look at the documentation:

<http://php.net/manual/en/language.constants.php>

So - yes the define is OK.

But your echo will not work, since NL is not automatically treated as a
placeholder. You have to write:

echo "This is ".NL." another line";

With variables this would be easier though:

$NL = ' ';
echo "This is $NL another line";
