php - Using loop for creating row in formatted email -

-

i want create formatted email. in email's body, need add loop creating table's row. don't know how make work. loop looks 

<tbody>     <?php $total = 0; for($i=0; $i<3; $i++) { ?>         <tr>             <td style="padding: 8px; line-height: 20px;">col 0</td>             <td>col 1</td>             <td>col 2</td>             <td>col 3</td>         </tr>     <?php }?> </tbody>

it works in normal html page. when tried make email's body , pass code string this,

    $body = "<tbody> <?php $total = 0; for($k=0; $k<3; $k++) { ?>      <tr> <td style='padding: 8px; line-height: 20px;'>1</td>      <td>asd</td> <td>ert</td> <td>qwe</td> </tr> <?php }?> </tbody>";  send($to, $subject, $body);

in email, doesn't create row @ all. advice?

main advice learn php syntax.

sample of proper code is:

$body = "<tbody>"; $total = 0;  for($k=0; $k<3; $k++) {     $body .= "<tr> <td style='padding: 8px; line-height: 20px;'>1</td>"          . "<td>asd</td> <td>ert</td> <td>qwe</td> </tr>"; }  $body .= "</tbody>";  send($to, $subject, $body)
