I have tried port 587,465 25 but still its not working.
我尝试了端口 587,465 25 但仍然无法正常工作。
<?php
if(isset($_POST['submit']))
{
$message=
'Full Name: '.$_POST['fullname'].'<br />
Subject: '.$_POST['subject'].'<br />
Phone: '.$_POST['phone'].'<br />

Comments: '.$_POST['comments'].'
';
require "phpmailer/class.phpmailer.php"; //include phpmailer class
// Instantiate Class
$mail = new PHPMailer();
// Set up SMTP
$mail->IsSMTP(); // Sets up a SMTP connection
$mail->SMTPAuth = true; // Connection with the SMTP does require authorization
$mail->SMTPSecure = "ssl"; // Connect using a TLS connection
$mail->Host = "smtp.gmail.com"; //Gmail SMTP server address
$mail->Port = 465; //Gmail SMTP port
$mail->SMTPSecure = "tls";
$mail->Encoding = '7bit';
// Authentication
$mail->Username = "[email protected]"; // Your full Gmail address
$mail->Password = "*********"; // Your Gmail password
// Compose
$mail->SetFrom($_POST['emailid'], $_POST['fullname']);
$mail->AddReplyTo($_POST['emailid'], $_POST['fullname']);
$mail->Subject = "New Contact Form Enquiry"; // Subject (which isn't required)
$mail->MsgHTML($message);
// Send To
$mail->AddAddress("[email protected]", "RahulName"); // Where to send it - Recipient
$result = $mail->Send(); // Send!
$message = $result ? 'Successfully Sent!' : 'Sending Failed!';
unset($mail);

First of all, while initiating PHPMailer send in the parameter truelike,
首先，在启动 PHPMailer 时发送参数， true例如，
$mailer = new PHPMailer(true);
This will help you to catch and handle exceptions.
这将帮助您捕获和处理异常。
Secondly, try this
其次，试试这个
$mailer->SMTPSecure = 'ssl'; // instead of tls

TLS on port 465 will not work - that port expects SSL. You should change it to port 587. You should not change to ssl for encryption as it's been deprecated since 1998.
端口 465 上的 TLS 将不起作用 - 该端口需要 SSL。您应该将其更改为端口 587。您不应更改为 ssl 进行加密，因为它自 1998 年以来已被弃用。
It would also help if you read the docsand base your code on an up-to-date example.

Try:
尝试：
$PHPMailer->SMTPOptions = array (
'ssl' => array (
'verify_peer' => false,
'verify_peer_name' => false,
'allow_self_signed' => true
)
);
works for me!
为我工作！
