[PHP] Testing for NULL

[Jesse Warden]

Hi, I am new... hope I am using this list correctly.

I am trying to test for a null value, and if it is null, then to use a
default value instead.  The login page that I have, I want to show nothing
in the username field unless it is passed a username from another PHP page
via the header function.  However, every time I write:

if($username == null){
echo "Username is null";
}

It executes the echo, but only after giving me an error.  Is there a way to
suppress this error or check for an undefined instead?
