Send mail using Gmail from php in localhost

I'm already know how to use phpmailer but I can't send mail which are using Gmail (I have in phpmailer all the configuration done like port, server name, etc) because it are using OAuth 2.0 and I already get my client id an all that but I'm getting this error:

 400. That’s an error.

Error: invalid_scope

Some requested scopes were invalid. {invalid=[email@gmail.com]}

when I try to connect to the server from the URL so what I must to do about that?

this is the file which I have the codes, I'm going to change some character to keep this private, I hope that you sand me with this some example how to use it.

copy and paste in a noteblock to have this more clear.

Solution

Using the pear mail library

// Pear Mail Library
require_once "Mail.php";

$from = '<from.gmail.com>';
$to = '<to.yahoo.com>';
$subject = 'Hi!';
$body = "Hi,\n\nHow are you?";

$headers = array(
    'From' => $from,
    'To' => $to,
    'Subject' => $subject
);

$smtp = Mail::factory('smtp', array(
        'host' => 'ssl://smtp.gmail.com',
        'port' => '465',
        'auth' => true,
        'username' => 'johndoe@gmail.com',
        'password' => 'passwordxxx'
    ));

$mail = $smtp->send($to, $headers, $body);

if (PEAR::isError($mail)) {
    echo('<p>' . $mail->getMessage() . '</p>');
} else {
    echo('<p>Message successfully sent!</p>');
}

I got it from here.
