Swiftmailer destinatarios mysql

Question

I need to send multiple emails stored in a mysql database with phpmailer, but when I want to execute it it returns a 500 page error, I understand that the problem is when I enter the data inside:

->setTo(["'".$row['email']."'" => "'".$row['nombre']."'"])

I clarify that everything works perfect, only that when I enter any type of variable or call to the db within the: -> setTo (["'". $ row [' email ']. "'" => "'". $ row [' name ']. "'"]) It returns an error. This is my complete code:

<?php 
include ('../db.php');
$query =$db->query("SELECT id, email, status, nombre, enviados FROM 
contactos WHERE email='example@gmail.com' OR 
email='example@icloud.com'");
require_once './vendor/autoload.php';
// Create the Transport
$transport = (new Swift_SmtpTransport('smtp.hostinger.com.ar', 
587))
->setUsername('example@example.com')
->setPassword('example')
   ;

 // Create the Mailer using your created Transport
 $mailer = new Swift_Mailer($transport);

 // Create a message
 $message = (new Swift_Message('msm'))
  ->setFrom(['example@example.com' => 'John Doe'])

 $datos_seleccionados = [];
  while($row = mysqli_fetch_array($query))
  {
   ->setTo(["'".$row['email']."'" => "'".$row['nombre']."'"])

   }
   ->setBody('INTENTO')
   ;
   // Send the message
   $result = $mailer->send($message);

What I need is for me to take multiple recipients stored in my database

Answer 1

<?php 
include ('../db.php');
$query =$db->query("SELECT id, email, status, nombre, enviados FROM 
contactos WHERE email='example@gmail.com' OR 
email='example@icloud.com'");
require_once './vendor/autoload.php';
// Create the Transport
$transport = (new Swift_SmtpTransport('smtp.hostinger.com.ar', 
587))
->setUsername('example@example.com')
->setPassword('example')
   ;

 // Create the Mailer using your created Transport
 $mailer = new Swift_Mailer($transport);



 $datos_seleccionados = [];
$toEmailList=[];
  while($row = mysqli_fetch_array($query))
  {
    $toEmailList[$row['email']]=$row['nombre'];

   }
 // Create a message
 $message = (new Swift_Message('msm'))->setFrom(['example@example.com' => 'John Doe'])->setTo($toEmailList)->setBody('INTENTO');
   // Send the message
   $result = $mailer->send($message);

Problem with your code is you are trying to concat key and value. You have to call all the function at once. Thanks
