13,066 PointsI don't understand the answer to this one...
$username = 'Treehouse';
The second if statement states if it doesn't equal Treehouse, than echo 'Hello $username'; but $username = 'Treehouse'.
I first responded to this with You are logged in, but that was wrong.
Then I tried Hello Treehouse because I thought maybe I was misunderstanding the first conditional statement. Now I am beyond confused with the whole thing... Please help!

Treehouse TeacherHi there! So, I'm going to post the example code here so we can see it a bit more clearly.
$username = "Treehouse";
if ($username) { // first if statement
if ($username != "Treehouse") {
echo "Hello $username";
}
} else { // matches the first if statement
echo "You must be logged in";
}
Ok, so first we set the $username
to be Treehouse and you seem to be understanding that part just fine. So now we go down to our first if statement. If the value stored in $username
is a truthy value, then we will execute what's inside that block. And this is what happens. We execute what's inside the block.
The trick is here that what's inside that block is yet another if
statement. It says that if the name is not "Treehouse", to echo out "Hello $username". But it is "Treehouse" so that echo doesn't happen.
And then we're done. Remember that an else statement matches with an if statement. I put in comments to show the if
and the else
that match up. If the condition in the if
statement evaluates to true (which it did) then the else
statement will not be run meaning that the "You must be logged in." echo never happens either.
The end result is that nothing is displayed.
Hope this helps!
