I'm trying to figure out how to get $_GET variable to work so the H1 tag becomes what the user imputted.

The question I have to answer is below.

Create a new PHP file named lab2.php.

2. Inside, add the HTML skeleton code and give its title “Lab Week 2"
3. Within the body tag, create a h2 tag with your full name
4. Add a section tag inside the body tag. 5.Create a form tag and use the $_GET method to get users to input their favorite artist. Store the user input into variables. 6.Create a submit button for the user to input their favorite artist. 7.Check whether the variable is empty or not .
