php - How to pass a 2 dimensional array value in a swift mailer setTo function -


i getting 2 dimensional array value result after loop.the value $chunk[$i][$j].and when passed value setto function, error showing as

warning: preg_match() expects parameter 2 string, array given in h:\xampp \htdocs\sngmarket\vendor\swiftmailer\swiftmailer\lib\classes\swift\mime\headers \mailboxheader.php line 350.

how solve this?.here code

$query = $em->createquery("select distinct u.emailaddress acmeregistrationbundle:userlist u");    $grp_emails[] = $query->getresult();     $chunk = array_chunk($grp_emails, 10);    $get_chunk_count = count($chunk);     for($i=0;$i<$get_chunk_count;$i++)    {     $count_inside_count = count($chunk[$i]);       for($j=0;$j<=$count_inside_count;$j++)       {         $mails=$chunk[$i][$j];          $message = \swift_message::newinstance()           ->setsubject('hello email')           ->setfrom('marketplace@socialnetgate.com')           ->setto($mails)           ->setreturnpath('gowtham@ephronsystems.com')           ->setbody('hello world');            $this->get('mailer')->send($message);           return array();       }    }

i think overthinking this.

have looked @ documentation on how send batch emails without recipients being aware of each other? in snippet each email contains 10 recipients, may better sending recipients, still pretty bad.

have @ sending emails in batch , @ plugins make sure don't reach limit of emails allowed send in time frame.
