basic if statement help

[jl9148]

hi.

i was wondering how to make an if statement with the below requirements

i only want the text to show if they are logged in

so kind of like if this shows something => $user_info[username]
then display whatever... if $user_info[username] displays nothing, then dont do anything..

so can anyone show me the correct code for this?

if(isset($user_info['username']) and $user_info['username'] !== '')
{
  // whatever should be displayed when they are logged in goes here.
}
