php - How not to display MySQL row if the row is empty -


i new php , trying solve this, went through many articles before asking here no better answer. fetching sql rows using mysqli_fetch_array($result)

if rows empty frontend displays empty row gives weird look. there should way not display empty rows database.

my code 

<?php include_once("config.php"); date_default_timezone_set('asia/kolkata'); //$timestamp = time(); $day = "" . date("d"); $dayt= "t" . date("d"); $dayr= "r" . date("d"); $result = mysqli_query($mysqli, "select * time_table regd='". $_session['textbox1'] ."'   order id desc");         while($res = mysqli_fetch_array($result)) {             echo "<tr>";             echo "<td style='width: 30%'>".$res[$dayt]."</td>";             echo "<td style='width: 30%'>".$res[$day]."</td>";             echo "<td style='width: 40%'>".$res[$dayr]."</td>";             }         ?>

i suggest change select query exclude rows empty column(s).

for example:

$result = mysqli_query($mysqli, "select * time_table regd='". $_session['textbox1'] ."' , some_possibly_empty_column <> '' order id desc");

or if column allows null value, better:

$result = mysqli_query($mysqli, "select * time_table regd='". $_session['textbox1'] ."' , some_possibly_empty_column not null order id desc");
