有多种方法可以做到这一点。

您可以考虑以下任何一项。

1、我的preferred:

foreach($group_emails as $email_address)
{
   wp_mail($email_address, \'my subject\', \'my message\', $headers);
}

按如下方式定义数组。

$group_emails = array(\'ceri@test.com\', \'craigj@test.com\', \'danyob@test.com\', \'geoffh@test.com\', \'ianc@test.com\', \'mark.butcher@test.com\', \'mickh@test.com\', \'mike@test.com\', \'stephd@test.com\', \'stuartj@test.com\' );

wp_mail($group_emails, \'my subject\', \'my message\', $headers);
