title: PHP and HTML checking if username is in database
body: <p>I'm trying to solve a problem pertaining to PHP.
  So far I have created an html login form login.html and a PHP file login-insert.php. I'm having trouble detecting if the username already exists in the database created using phpmyadmin. I'm very new to coding in PHP so any help is appreciated</p>
