在html表中的php + mysql计算一个百分比

Question

My current code:

<td>
   <?php echo $row['feild1'] + $row['feild2'] + $row['feild3'] + $row['feild4'] + $row['feild5'] + $row['feild6'] + $row['feild7'] + $row['feild8'] + $row['feild9'] + $row['feild10'] + $row['feild11'] + $row['feild12'] + $row['feild13'] + $row['feild14'] / 42; ?>
</td>

I'm trying to produce a percentage but it just seems to add the values together.

Answer 1

<td><?php echo ($row['feild1'] + $row['feild2'] + $row['feild3'] + $row['feild4'] + $row['feild5'] + $row['feild6'] + $row['feild7'] + $row['feild8'] + $row['feild9'] + $row['feild10'] + $row['feild11'] + $row['feild12'] + $row['feild13'] + $row['feild14']) / 42; ?></td>

Like so.

Also you misspelled field. Not feild.
