Как отправить письмо на gmail с помощью php?

Создаю приложение, чтобы письма отправлялись на все почтовые ящики. И у меня возникла проблема с отправкой письма на gmail.

Вот код:

<?php

class SendMailSmtpClass {


    public $smtp_username;
    public $smtp_password;
    public $smtp_host;
    public $smtp_from;
    public $smtp_port;
    public $smtp_charset;
    
    public function __construct($smtp_username, $smtp_password, $smtp_host, $smtp_from, $smtp_port = 25, $smtp_charset = "utf-8") {
        $this->smtp_username = $smtp_username;
        $this->smtp_password = $smtp_password;
        $this->smtp_host = $smtp_host;
        $this->smtp_from = $smtp_from;
        $this->smtp_port = $smtp_port;
        $this->smtp_charset = $smtp_charset;
    }
    

    function send($mailTo, $subject, $message, $headers) {
        $contentMail = "Date: " . date("D, d M Y H:i:s") . " UT\r\n";
        $contentMail .= 'Subject: =?' . $this->smtp_charset . '?B?'  . base64_encode($subject) . "=?=\r\n";
        $contentMail .= $headers . "\r\n";
        $contentMail .= $message . "\r\n";
        
        try {
            if(!$socket = @fsockopen($this->smtp_host, $this->smtp_port, $errorNumber, $errorDescription, 30)){
                throw new Exception($errorNumber.".".$errorDescription);
            }
            if (!$this->_parseServer($socket, "220")){
                throw new Exception('Connection error');
            }
         
            fputs($socket, "HELO " . $this->smtp_host . "\r\n");
            if (!$this->_parseServer($socket, "250")) {
                fclose($socket);
