如何在 php 中使用 SMTP 发送电子邮件

I want to send email with SMTP in my project, previously i write php mail() in my project but now my client want that i should use SMTP. I search about this but i get nothing any proper solution for this.

在我的 php mail() 中我发送名称、主题和评论，那么我如何在 SMTP 中执行此操作.

In my php mail() i send name, subject and comment, so how can i do this in SMTP.

这是我的代码:

$payer_email = "Your Email";
$subject = "Your Subject";
$message = 'Dear '.$name.',
            Thank you for your purchase from '.$site_url.'. The details of your purchase are below.
            Transaction ID: '.$txn_id.'
            Item Name: '.$item_name.'
            Payment Amount: '.$payment_amount.'
            Payment Amount: '.$payment_status.'
            Paid to: '.$receiver_email.'
            Thanks and Enjoy!';

$headers .= 'From: ' .$from. "
" .'Reply-To: ' .$from . "
";
$headers  .= 'MIME-Version: 1.0' . "
";
$headers  .= "Content-Type: text/html; charset=iso-8859-1 ";

//mail to buyer
mail( $payer_email , $subject, $message, $headers );

看看PHP Mailer:

Take a look at PHP Mailer:

https://github.com/PHPMailer/PHPMailer

该页面的示例:

<?php
require 'PHPMailerAutoload.php';

$mail = new PHPMailer;

//$mail->SMTPDebug = 3;                               // Enable verbose debug output

$mail->isSMTP();                                      // Set mailer to use SMTP
$mail->Host = 'smtp1.example.com;smtp2.example.com';  // Specify main and backup SMTP servers
$mail->SMTPAuth = true;                               // Enable SMTP authentication
$mail->Username = 'user@example.com';                 // SMTP username
$mail->Password = 'secret';                           // SMTP password
$mail->SMTPSecure = 'tls';                            // Enable TLS encryption, `ssl` also accepted
$mail->Port = 587;                                    // TCP port to connect to

$mail->From = 'from@example.com';
$mail->FromName = 'Mailer';
$mail->addAddress('joe@example.net', 'Joe User');     // Add a recipient
$mail->addAddress('ellen@example.com');               // Name is optional
$mail->addReplyTo('info@example.com', 'Information');
$mail->addCC('cc@example.com');
$mail->addBCC('bcc@example.com');

$mail->WordWrap = 50;                                 // Set word wrap to 50 characters
$mail->addAttachment('/var/tmp/file.tar.gz');         // Add attachments
$mail->addAttachment('/tmp/image.jpg', 'new.jpg');    // Optional name
$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';

if(!$mail->send()) {
    echo 'Message could not be sent.';
    echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
    echo 'Message has been sent';
}
