$this->loadmodel('asindividualdetails'); $emaildetails = $this-> asindividualdetails->find('all',['fields'=>'email']); $emaildetails = $emaildetails->toarray();    foreach ($emaildetails $key => $a) {          $this->loadmodel('domainemaildetails');         $domainemaildetails = $this-> domainemaildetails->find('all')->first();         $domainemaildetails = $domainemaildetails->toarray();         $host     = 'ssl://'.$domainemaildetails['host_name'];         $username = $domainemaildetails['user_name'];         $password = $domainemaildetails['user_password'];         $port     = $domainemaildetails['port'];         $email_to = $a['email'];         $sendername = 'abc';         $email_id   ='xyz110@gmail.com';          email::configtransport('webmail', [                                                           'classname' => 'smtp',                                                           'host' => $host,                                                           'port' => $port,                                                           'timeout' => 30,                                                           'username' => $username,                                                           'password' => $password,                                                           'client' => null,                                                           'tls' => null,                                             ]);                       ////////// send mail                        $email = new email('webmail');                       $email  ->template('default','default')                               ->emailformat('both')                               ->from([$username => $sendername])                               ->to($email_to)                               ->replyto($email_id)                               ->subject('client message');                       $response = $email->send('my msg');                        if($response){                           echo 'success';                       }else{                           echo 'failed';                       }  }

when run script 1 mail send , after error has come :

cannot modify existing config "webmail"

how solve error , send mail recipient mail address.

make email configuration outside of loop. don't want try , establish configuration every time send emails - 1 time. send emails based on 1 configuration.

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this
