Error# Fatal error: Uncaught Error: Call to undefined function mysqli_fetch() in C:\xampp\htdocs\gsoft\assigment\tabledb.php:9 Stack trace: #0 {main} thrown in C:\xampp\htdocs\gsoft\assigment\tabledb.php on line 9

Answer 1

if you want fetch without index use mysqli_fetch_assoc().
Or
if you want to fetch with index use mysqli_fetch_array()
And i think you are doing wrong here because your table tag is inside while loop and your <thead> too.
i think it should be outside of while loop. and you have syntax error in your query and you have one extra <th>
your full code.
<?php
$host="localhost";
$user="root";
$pwd="";
$db="assigment";
$conn=mysqli_connect($host,$user,$pwd,$db);
$query="SELECT * FROM tdata ";
$result=mysqli_query($conn,$query); ?>
<table class="table">
<thead>
<tr>
<th>Full Name</th>
<th>Email</th>
<th>Birthday</th>
<th>Gender</th>
<th>Intrests</th>
<th>Address</th>
</tr>
</thead>
<tbody>
<?php while ($row=mysqli_fetch_assoc($result)) { ?>
<tr>
<td><?php echo $row['full_name']; ?></td>
<td><?php echo $row['your table field name']; ?></td>
<td><?php echo $row['your table field name']; ?></td>
<td><?php echo $row['your table field name']; ?></td>
<td><?php echo $row['your table field name']; ?></td>
<td><?php echo $row['your table field name']; ?></td>
</tr>
<?php }
?>
</tbody>
</table>

Answer 2

use mysqli_fetch_array function instead of mysqli_fetch

Answer 3

Use mysqli_fetch_array instead of mysqli_fetch
Also your table is inside the loop
