If statements in PHP?

[barbedwire103]

How do i get something to show only if the user is logged in? For example, "log
out" should only show if the user is logged in and "log in" should only show if
the user is not logged in. How would i do this in PHP? Thanks for you help!

Logging in and out is normally controlled by session variables. So, if
you have a session variable called 'username', you would handle it like
this:

if (isset($_SESSION['username'])) {
// code for logging out
}
else {
// code for logging in
}

If you are using the DW User Authentication server behavior, you should
be aware that it breaks in modern versions of PHP. See the following
explanation (you need read only the first post):
