  foreach ( $values as $key => $val ) {

How to use sfMail to encode Body of Japanese Email.

The Japanese Email usually use ISO-2022-JP. But, I want to use UTF-8 of any Email template files. For example...

I create PROJECT_DIR/lib/myMail.class.php

myMail.class.php

<?php
 
class myMail extends sfMail
{
  public function setBody ($body)
  {
    parent::setBody(mb_convert_encoding($body, "JIS", "UTF-8"));
  }
}
 
?>

OK, Use this class from your Action.

actions.class.php

  public function executeSendmail()
  {
    $mail = new myMail();
    ....
  }
