If ($username) is what?

Hi.

I don't quite understand this if statement. I would expect it to be if ($username = x) or something like that. It's probably related to the line below, but I don't quite see the relation.

Hi Jakob Tolstrup,

if ($username) is a check if there is content to $username. So the answers can be true or false. It the quiz it is true so the next if ($username != "Treehouse") will be checked.

Hope i could help you. Kind regards, Alan

  • the answer of that quiz question is "Nothing will be displayed" :)
