<th>Stock Available</th>
<th>Product Name</th>

</tr>

Please update your html.
<?php
$q= mysqli_query($conn,"SELECT * FROM products");
while ($row=mysqli_fetch_array($q)) {
$id = $row['id'];
$product_name = $row['product_name'];
$available_stock = $row['available_stock'];
echo '
<tr>
<td>'.$available_stock.'</td>
<td>'.$product_name.'</td>
<td><input type="number" min="1" class="form-control" name="qty['.$id .'][]"></td>
<input type="hidden" name="id['.$id .'][]" value="'.$id.'">
<tr>
';
}
