Hi, I wrote a php project 2 years ago. I am totally lost right now.
what is differnt between $userName, $_GET['userName'] and
$_REQUEST['userName']? In my past project, I remember i can use
$userName as a variable, but i dont know why I cannot use it again
because of using different version of php and apache? What is
different between "printf", "print" and "echo"? Can you guys help me
fix my a little project too? Thanks
