Treehouse TeacherHi there, jonny black! Remember that double quotes are used when you need the value of a variable as a part of the string. If you had tried to display the value of $string_one
to the console right now, it would display:
$fullName was the original creator or PHP
Literally, it would look just like that without a new line character, period, but most importantly, instead of "Rasmus Lerdorf" in place of $fullName
it would say the variable name "$fullName" which isn't what we're after.
First, you will need double quotes so that it gives the value stored in $fullName
instead of the string "$fullName". Secondly, you need to echo the string to display it. Finally, the string should end with a period/full stop and a new line character.
This is the line you're looking for:
echo "$fullName was the original creator of PHP.\n";
Hope this helps!
