【问题描述】：

我想在我的项目中使用SMTP 发送电子邮件，以前我在我的项目中写php mail()，但现在我的客户希望我应该使用SMTP。我对此进行了搜索，但没有得到任何适当的解决方案。

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

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

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

请给我一些建议或简单而好的教程。

【参考方案1】：

看看 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 = '[e-mail]';                 // 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 = '[e-mail]';
$mail->FromName = 'Mailer';
$mail->addAddress('[e-mail]', 'Joe User');     // Add a recipient
$mail->addAddress('[e-mail]');               // Name is optional
$mail->addReplyTo('[e-mail]', 'Information');
$mail->addCC('[e-mail]');
$mail->addBCC('[e-mail]');

$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';

请告诉我，我得到“PHPmailer”文件夹并放入我的项目并编写此代码。

你应该下载PHPMailer，把它放到你的项目目录中，并像require 'path/to/PHPMailer/PHPMailerAutoload.php;一样将它包含在你的项目中，然后如上所示使用它

抱歉耽搁了......这是在“localhost”上工作还是只在在线服务器上工作......因为我在localhost上测试它但它没有工作

它也应该在localhost上工作，这个类实现了SMTP协议并连接到您的邮件服务器以发送电子邮件。

如果您使用的是 WP，您可以在脚本中包含内置类 wp-includes/class-phpmailer.php

【参考方案2】：

$mail = new PHPMailer();
$mail->IsSMTP();
$mail->CharSet = 'UTF-8';

$mail->Host       = "mail.example.com"; // SMTP server example
$mail->SMTPDebug  = 0;                     // enables SMTP debug information (for testing)
$mail->SMTPAuth   = true;                  // enable SMTP authentication
$mail->Port       = 25;                    // set the SMTP port for the GMAIL server
$mail->Username   = "username"; // SMTP account username example
$mail->Password   = "password";        // SMTP account password example

【参考方案3】：

请试试这个

为 SMTP 设置“library.php”创建库文件：

    <?php
    error_reporting(0);
    define("SMTP_HOST", "SMTP_HOST_NAME"); //Hostname of the mail server
    define("SMTP_PORT", "SMTP_PORT"); //Port of the SMTP like to be 25, 80, 465 or 587
    define("SMTP_UNAME", "VALID_EMAIL_ACCOUNT"); //Username for SMTP authentication any valid email created in your domain
    define("SMTP_PWORD", "VALID_EMAIL_ACCOUNTS_PASSWORD"); //Password for SMTP authentication
    ?>

Make the form post and do the below actions:

<?php
include 'library.php';
include "classes/class.phpmailer.php"; // include the class file name
if(isset($_POST["send"]))
    $email = $_POST["email"];
    $mail   = new PHPMailer; // call the class
    $mail->IsSMTP();
    $mail->Host = SMTP_HOST; //Hostname of the mail server
    $mail->Port = SMTP_PORT; //Port of the SMTP like to be 25, 80, 465 or 587
    $mail->SMTPAuth = true; //Whether to use SMTP authentication
    $mail->Username = SMTP_UNAME; //Username for SMTP authentication any valid email created in your domain
    $mail->Password = SMTP_PWORD; //Password for SMTP authentication
    $mail->AddReplyTo("[e-mail]", "Reply name"); //reply-to address
    $mail->SetFrom("[e-mail]", "Asif18 SMTP Mailer"); //From address of the mail
    // put your while loop here like below,
    $mail->Subject = "Your SMTP Mail"; //Subject od your mail
    $mail->AddAddress($email, "Asif18"); //To address who will receive this email
    $mail->MsgHTML("<b>Hi, your first SMTP mail has been received. Great Job!.. <br/><br/>by <a href='http://asif18.com'>Asif18</a></b>"); //Put your body of the message you can place html code here
    $mail->AddAttachment("images/asif18-logo.png"); //Attach a file here if any or comment this line,
    $send = $mail->Send(); //Send the mails
    if($send)
        echo '<center><h3 style="color:#009933;">Mail sent successfully</h3></center>';
    
    else
        echo '<center><h3 style="color:#FF3300;">Mail error: </h3></center>'.$mail->ErrorInfo;
    

?>

没有第三方脚本的代码怎么样？我发现的一切都在使用 PHPMailer 或其他一些我不能/不想使用的脚本。好吧，我可以对 PHPMailer 进行逆向工程，并尝试仅获取通过 SMTP 而不是 PHP 邮件发送所需的内容。
