So I have my code for a member system and this line of code checks if the user has logged in to display his/her name but I am getting errors.

PHP

<?php
		// Check if username session is set or not 
		//if it is set then say Hi with the username
		//If it is not then display login/Register
		if (!isset($_SESSION['user'])) {
			echo "$lgrreg";
		}else{
			echo "Hi $username! ";
		}
			
		$lgout = '<a href="logout.php">Logout?</a>';
			
		$lgrreg = '<a href="membersys.php">
		Login/Register
		</a>';
?>

At :
Line 26: $lgrreg = '<a href="membersys.php">

I have some errors

Notice: Undefined variable: lgrreg in C:\xampp\htdocs\index.php on line 26

But how have I not defined it?

As I see, the message itself looks a little bit confusing, becouse the problem is elsewhere. But look this way: in the if statement you are echoing that variable, but at that point it is undefined. I suggest you put the whole if statement at the end of the section, after you set those two variables. Should not make any difference, but try to avoid multiline string constant for a try.
