I have this line of codes
<html>
<form>
Please type your name here: <br>
<input type=text name=username><br><br>
<input type=submit value="Submit data">
</form>
<br><br>
You typed:
<?php
$username;
echo ($username);
?>
</html>
the problem is, everytime I open that php file in browser, I receive a notification like this:
Notice: Undefined variable: username in /opt/lampp/htdocs/formsvar.php on line 13
What's wrong with my code?
Please help me. Thanks.
