title: php Data not stored in mySQL database using XAMPP
body: <p>I have this code and I am using the latest version of XAMPP:</p>
  
  <p>filename: store.html</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  
  &lt;html&gt;
  &lt;body&gt;
  
  &lt;form action="store.php" method="post"&gt;
  User input: &lt;input type="text" name="userinput"&gt;&lt;br&gt;
  &lt;input type="submit"&gt;
  &lt;/form&gt;
  
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>filename: store.php</p>
  
  <pre><code>&lt;?php
  
  $servername = "localhost";
  $username = "root";
  $password = "";
  $dbname = "database";
  
  
  // Create connection
  $conn = new mysqli($servername, $username, $password, $dbname);
  
  // Check connection
  if ($conn-&gt;connect_error) {
       die("Connection failed: " . $conn-&gt;connect_error);
   } 
   echo "Connected successfully";
  
  $input = $_POST["userinput"];
  
  
  $sql = "INSERT INTO table_1 (s_num)
  VALUES ('$input')";
  
  
   ?&gt;
  </code></pre>
  
  <p>Whatever I do, no data is added to the database. Please help. Thank you.</p>
