I'm very confused of what you are asking?

You mean you want to delete a row from the DB?

Then used this:

$sql = "DELETE FROM table WHERE row =''";

If this is not what you asking. Then explain a little more what you talking about.

no i donot want to remove a row from db i donot want to display

echo "<td><a href='request-for-approval.php?id=".$row['cid']."& sid=".$row['sid']."'>Apply!</a></td>"; 

when the status is applied

basically i want to remove the option for apply if user already applied hope u understand my question

How about something like:

echo "<td>";
if ("I must display") {
    echo "<a href='request-for-approval.php?id=".$row['cid']."& sid=".$row['sid']."'>Apply!</a>";
}
else {
    echo "&nbsp;";
}
echo "</td>";
