在回复PHP中添加多个电子邮件地址

Question

In Already build project management system software. I like to Add some more feature. In my Application there is a functionality of messages means one user can sent message to his client or another user that message receiver can see his dashboard and he also receive that message to his mail inbox

so that i create code that send that message to both my email address and that users email address

but the problem is that when receiver reply to that mail message only went to only one email address that i put in reply-to

So how can i put more than one email address in php mail or any other way to send reply mail to multiple email address

here is my code for send mails

function send_notification($sender, $receiver, $super, $email, $subject, $text ) {
    $instance =& get_instance();
    $instance->load->helper('file');
    $instance->load->library('parser');

    $data["core_settings"] = Setting::first(array('conditions' => array('admin_id = ?', $super)));

    $instance->email->from($data["core_settings"]->email, $data["core_settings"]->company);

    $instance->email->reply_to("def@example.com", "mnp", "abc@example.com", "ABC DEF");

            $instance->email->to($email); 
            $instance->email->subject($subject); 
            //Set parse values
            $parse_data = array(
                                'company' => $data["core_settings"]->company,
                                'link' => base_url(),
                                'logo' => '<img src="'.base_url().''.$data["core_settings"]->logo.'" alt="'.$data["core_settings"]->company.'"/>',
                                'invoice_logo' => '<img src="'.base_url().''.$data["core_settings"]->invoice_logo.'" alt="'.$data["core_settings"]->company.'"/>',
                                'message' => $text
                                );
            $email_invoice = read_file('./application/views/'.$data["core_settings"]->template.'/templates/email_notification.html');
            $message = $instance->parser->parse_string($email_invoice, $parse_data);
            $instance->email->message($message);
            $instance->email->send();

}

Answer 1

Make a for loop that goes trough all your email addresses. You can put your email addresses in a database or array what ever you prefer.

Using an array:

$emailAdresses = array("example@mail.com", "example2@mail.com");
foreach ($emailAdresses as $i) {
  mail($emailAdresses[$i],"","");
}

Answer 2

You can try some thing like this

$list = array('one@example.com', 'two@example.com', 'three@example.com');
$instance->email->reply_to($list, 'Your Name');

OR

$instance->email->reply_to('one@example.com, two@example.com, three@example.com', 'Your Name');

I hope this helps you!
