Class MailerPHP strange behaviour (looping array of address) - php

Question

I am using Class MailerPHP to send emails on the website. Actually is working perfect as it have to work but there is some strange stuff that i can not figure out why is like this.
1. I have an array of address that i am sending emails, the array is like this:
$email = new sendEmail();
$_ADMIN_EMAIL = array('first_email', 'second_email', 'third_email');
$email->setEmail($_ADMIN_EMAIL);
The problem is when is sending emails, is sending 3 emails:
1. sending to first_email
2. after sending to first_email and second_email
3. and at the end sending to first_email, second_email and third_email
I would like to send only one to all 3 and do not send 3 times email, i do not understand why is sending like this.
2. And second problem is i am using my Google account to connect to the SMTP to send emails, and i do not know why in the TO field of the email is showing my gmail address that i connect to the SMTP, i setup which address to show there and is showing + my gmail account:
I have this configuration only and i didn't put anywhere else my gmail account only for SMTP connection:
public $Username = 'my_gmail_account_to connect_to_smtp';
public $Password = 'my_gmail_account_password';
The result of this when i get emails is first email that i setup to show for reply + my_gmail_account_to connect_to_smtp, i need to take out my_gmail_account_to connect_to_smtp from the email that the user will not see it.
If you need for information about the code i use please let me know i will put.
All the code that i send email:
$_ADMIN_EMAIL = array("first_email", "second_email", "third_email");
$email2 = new sendEmail();
$email2->setSubject("Subject");
$email2->setUserName($_USER['name']);
$email2->setMT4Account($_USER['login']);
$email2->setDate($_USER['date']);
$email2->setAmount($_USER['amount']);
$email2->setCurrency($_USER['currency']);
$email2->setRegisteredBankAccount($_USER['type']);
$email2->setBankAccountName($_USER['card']);
$email2->setTemplate('template_for_the_email');
$email2->setEmail($_ADMIN_EMAIL);
echo $email2->send();

Answer 1

Try this:
$_ADMIN_EMAIL = array('first_email', 'second_email', 'third_email');
foreach($_ADMIN_EMAIL as $ademail)
{
$email->setEmail($ademail);
}
