Question

Hello. Who will tell you how to work with smtp.gmail.com?
Before that, I used ssl://smtp.yandex.ru, but since access has now been closed, I can already use this method.
I use this script

function smtpmail($to='', $mail_to, $subject, $message, $headers='') {
        $mft_config['smtp_username'] = 'username';
        $mft_config['smtp_port'] = '465';
        $mft_config['smtp_host'] =  'ssl://smtp.gmail.com';
        $mft_config['smtp_password'] = 'password';
        
        $mft_config['smtp_debug'] = true;
        $mft_config['smtp_charset'] = 'utf-8';
        $mft_config['smtp_from'] = 'Administrator';
        $SEND = "Date: ".date("D, d M Y H:i:s") . " UT\r\n";
        $SEND .= 'Subject: =?'.$mft_config['smtp_charset'].'?B?'.base64_encode($subject)."=?=\r\n";
        if ($headers) $SEND .= $headers."\r\n\r\n";
        else
        {
            $SEND .= "Reply-To: ".$mft_config['smtp_username']."\r\n";
            $SEND .= "To: \"=?".$mft_config['smtp_charset']."?B?".base64_encode($to)."=?=\" <$mail_to>\r\n";
            $SEND .= "MIME-Version: 1.0\r\n";
            $SEND .= "Content-Type: text/html; charset=\"".$mft_config['smtp_charset']."\"\r\n";
            $SEND .= "Content-Transfer-Encoding: 8bit\r\n";
            $SEND .= "From: \"=?".$mft_config['smtp_charset']."?B?".base64_encode($mft_config['smtp_from'])."=?=\" <".$mft_config['smtp_username'].">\r\n";
            $SEND .= "X-Priority: 3\r\n\r\n";
        }
        $SEND .=  $message."\r\n";
         if( !$socket = fsockopen($mft_config['smtp_host'], $mft_config['smtp_port'], $errno, $errstr, 30) ) {
          if ($mft_config['smtp_debug']) echo $errno."<br>".$errstr;
          return false;

      function server_parse($socket, $response, $line = __LINE__) {
        
        $mft_config['smtp_username'] = 'username';
        $mft_config['smtp_port'] = '465';
        $mft_config['smtp_host'] =  'ssl://smtp.gmail.com';
        $mft_config['smtp_password'] = 'password';

        while (@substr($server_response, 3, 1) != ' ') {
          if (!($server_response = fgets($socket, 256))) {
            if ($mft_config['smtp_debug']) echo "<p>Trable with send letter!</p>$response<br>$line<br>";

        }
        return true;
      }
      $message = 'Заявка на скидку 10%';
      smtpmail('<email>', 'email', 'Скидка 10%', $message, 'utf-8');

I've tried all the options I found on the net, but nothing helps.
Who had a similar problem, help please?
