我将代码组织成这样：

<?php

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;
use PHPMailer\PHPMailer\SMTP;

require '/home/g/grablmz2/psywomenandmen.ru/public_html/ads/libs/PHPMailer/Exception.php';
require '/home/g/grablmz2/psywomenandmen.ru/public_html/ads/libs/PHPMailer/PHPMailer.php';
require '/home/g/grablmz2/psywomenandmen.ru/public_html/ads/libs/PHPMailer/SMTP.php';


$mail = new PHPMailer(true);

try {
    echo 'start';
    //Server settings
    $mail->SMTPDebug = SMTP::DEBUG_SERVER;                      // Enable verbose debug output
    $mail->isSMTP();                                            // Send using SMTP
    $mail->Host       = 'smtp.gmail.com';                    // Set the SMTP server to send through
    $mail->SMTPAuth   = true;                                   // Enable SMTP authentication
    $mail->Username   = 'hidden';                     // SMTP username
    $mail->Password   = 'hidden';                               // SMTP password
    $mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS;         // Enable TLS encryption; `PHPMailer::ENCRYPTION_SMTPS` encouraged
    $mail->Port       = 587;                                    // TCP port to connect to, use 465 for `PHPMailer::ENCRYPTION_SMTPS` above

    //Recipients
    $mail->setFrom('hidden', 'Mailer');
    $mail->addAddress('hidden', 'Michael');

   // Content
    $mail->Subject = 'Test';
    $mail->Body    = 'Test';

    $mail->send();
    echo 'Message has been sent';
} catch (Exception $e) {
    echo "Message could not be sent. Mailer Error: {$mail->ErrorInfo}";
}

Gmail 中的“安全性较低的应用程序”已开启。通过复制并粘贴到浏览器来对登录名和密码进行双重检查。

我在端口和其他选项方面做错了吗？

【解决方案1】：

不，您在端口和选项方面没有做错任何事情，它们都很好。你做错的是没有阅读错误信息。

这提供了一个指向页面的链接，该页面可以告诉您更多信息，并且还有一个简单的说明：“请通过您的网络浏览器登录，然后再试一次”。这意味着您应该通过浏览器登录 gmail，然后再尝试再次运行您的脚本。

您可能还需要执行涉及 gmail 解锁验证码页面的进一步步骤，但您可以通过阅读包含 full details of this exact issue 的 PHPMailer 故障排除指南来了解这一点。
