title: How to fix fatal error in PHP?
body: <p>I found a system that can generate a report I would like to study this system but when I try to generate the system the login was OK but when I put the password and username this error comes out:</p>
  
  <blockquote>
    <p>Fatal error: Call to undefined function mysql_select_db() in
    C:\xampp\htdocs\inventory\inventory\db.php on line 8</p>
  </blockquote>
  
  <p>Can anyone else tell me what is the problem in this system?</p>
