php - Swift Mailer sending only last row of table -

i pulling email addresses database table , iterating through them send email. if comment out line $mailer->send($message); email sent out, last row in table. if leave line in, email sent recipients, sends twice last row in table. doing wrong?

    <?php      // pull data database     $query = "select emailaddress, firstname, lastname test_table";      if ($result = mysqli_query($link, $query))     {         /* put data array */         while($row = mysqli_fetch_assoc($result))         {             $swimmers[] = $row;         }          /* free result set */         mysqli_free_result($result);     }      /* close connection */     mysqli_close($link);      /* create replacements array */     $replacements = array();     foreach ($swimmers $swimmmer) {         $replacements[$swimmer["emailaddress"]] = array (             "{firstname}" => $swimmer["firstname"],             "{lastname}" => $swimmer["lastname"],             "{fullname}" => ($swimmer["firstname"] . ' ' . $swimmer["lastname"])         );     }      /* create transport */     $transport = swift_smtptransport::newinstance()         ;      // create mailer using created transport     $decorator = new swift_plugins_decoratorplugin($replacements);     $logger = new swift_plugins_loggers_echologger();     $mailer = swift_mailer::newinstance($transport);     $mailer->registerplugin($decorator);     $mailer->registerplugin(new swift_plugins_loggerplugin($logger));      // create message     $message = swift_message::newinstance()          // give message subject         ->setsubject('stuff')          // set address associative array         ->setfrom(array('stuff' => 'stuff'))          // give body         ->setbody('stuff', 'text/html')          // , optionally alternative body         ->addpart('stuff', 'text/plain')           // optionally add attachments         ->attach(swift_attachment::frompath('stuff'))     ;          // set addresses associative array         foreach($swimmers $swimmer)          {             echo $swimmer['emailaddress'];             $message->setto($swimmer["emailaddress"], $swimmer["fullname"]);             //$mailer->send($message);         }      echo $logger->dump();          // pass variable name send() method         if (!$mailer->send($message, $failures))         {             echo "failures:";             print_r($failures);         }      ?> 

with function (after echo $logger->dump();)

 if (!$mailer->send($message, $failures)) 

you resend last email

the $mailer->send($message, $failures) send email if inside if eval
