title: Can't insert data into database in php
body: <p>Here's my connection codes and query:</p>
  
  <pre><code>$conn = new mysqli('localhost' , 'root' , '#PASSWORD_HERE#' , 'NSEG');
  
      if($conn-&gt;connect_error)
      {
          die("Unable to connect!");
      }
  
      $Query = "INSERT INTO professors(id , Username , FirstName , LastName , Gender , Email) VALUES (NULL , '$username' , '$fname' , '$lname' , '$Gender' , '$Email')";
      $conn-&gt;query($Query);
  
      $conn-&gt;close();
  </code></pre>
  
  <p>But when I submit and I go to php my admin it doesn't show anything the "prfessors" table!
  What Should I do?!</p>
