That means your SELECT query isn't working. You'll need to run it separately on the server to see what the results are (i.e., what the error is).

<?php
//reading the database
$conn=mysqli_connect ("localhost", "root", "");
      if (!$conn) {
          echo "server connction error";
      }
      $db_conn = mysqli_select_db($conn, "test2");
      $sql = "select id, name, email, passwd from f_user";
      $query = mysqli_query($conn, $sql);
      
?>
<table>
      <tr>
            <td><strong>username</strong></td>
            <td><strong>email</strong></td>
            <td><strong>Passwd</strong></td>
            <td><strong>Action</strong></td>
      </tr>
      <?php
if (mysqli_num_rows($query)>=1){
      while ($row=mysqli_fetch_assoc($query)){

      ?>
      <tr>
            <td><?php echo $row['name'];?></td>
            <td><?php echo $row['email'];?></td>
            <td><?php echo $row['passwd'];?></td>
            <td><a href="edit.php?id=<?php echo $row['id'];?>"> Edit</a> I <a href
            ="delete.php?id=<?php echo $row['id']; ?>">Delete</a></td>
      </tr>
      <?php
}}
?>
