title: Destroy session upon refresh
body: <p>I am trying to destroy the session information upon refresh. The problem here is that everytime I refresh, the data still appears on the table. How do i set the table data to null upon refresh?</p>
  
  <pre><code>&lt;?php
          $value = $_SESSION["data"];
          $query = "SELECT * FROM datas WHERE CONCAT(`code`,`name`, `ID`, `cost`) LIKE '%".$value."%'";
          $search = filterTable($query);
      if (isset($_SESSION["data"])) {
         if (basename($_SERVER['PHP_SELF']) != $_SESSION["data"]) {
              session_destroy();
         }
      }
      function filterTable($query)
      {
          $connect = mysqli_connect("localhost", "root", "", "databasename");
          $filter = mysqli_query($connect, $query);
          return $filter;
      }
  
  ?&gt;
