PHP 邮件程序在本地主机上工作还是这里有问题
尝试使用 PHP 邮件程序 (localhost) 发送电子邮件时，我不断收到错误消息。或者 php 邮件程序无法在本地主机上运行吗？
<?php
//Import PHPMailer classes into the global namespace
//These must be at the top of your script, not inside a function
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\SMTP;
use PHPMailer\PHPMailer\Exception;
require 'src/Exception.php';
require 'src/PHPMailer.php';
require 'src/SMTP.php';
//Load Composer's autoloader
require 'vendor/autoload.php';
//Create an instance; passing `true` enables exceptions
$mail = new PHPMailer(true);
try {
//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 = 'default@gmail.com'; //SMTP username
$mail->Password = '00000120'; //SMTP password
// $mail->SMTPSecure = PHPMailer::ENCRYPTION_SMTPS; //Enable implicit TLS encryption
$mail->Port = 465; //TCP port to connect to; use 587 if you have set `SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS`
//Recipients
$mail->setFrom('NatsuDragneelxd42069@gmail.com', 'Mailer');
$mail->addAddress('Received@gmail.com', 'Joe User'); //Add a recipient
//$mail->addAddress('ellen@example.com'); //Name is optional
$mail->addReplyTo('Noreply@gmail.com', 'Info');
// $mail->addCC('cc@example.com');
// $mail->addBCC('bcc@example.com');
//Attachments
// $mail->addAttachment('/var/tmp/file.tar.gz'); //Add attachments
// $mail->addAttachment('/tmp/image.jpg', 'new.jpg'); //Optional name
//Content
$mail->isHTML(true); //Set email format to HTML
$mail->Subject = 'Here is the subject';
$mail->Body = 'This is the HTML message body <b>in bold!</b>';
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';
$mail->send();
echo 'Message has been sent';
} catch (Exception $e) {
echo "Message could not be sent. Mailer Error: {$mail->ErrorInfo}";
}
这是我得到的错误：
服务器-> 客户端： SMTP 错误：无法连接到 SMTP 主机。 Message could not be sent. Mailer Error: SMTP 错误：无法连接到 SMTP 主机。
