php - 请任何人都可以解释这个代码，我正在处理发送 php 代码的电子邮件，我在 GitHub 上找到了这个代码？

问题描述

private function getSMTPSettingList()
{
    $configs = OW::getConfig()->getValues('base');

    return array(
        'connectionPrefix' => $configs['mail_smtp_connection_prefix'],
        'host' => $configs['mail_smtp_host'],
        'port' => $configs['mail_smtp_port'],
        'user' => $configs['mail_smtp_user'],
        'password' => $configs['mail_smtp_password']
    );
}

这是我在 oxwal mail service.php 的 GitHub 上找到的代码

我是 php 新手，所以我从这段代码中得到帮助……但我什么都不懂……

这是整个代码现在我如何使用此功能从我的网站发送电子邮件...

解决方案

这是发送邮件的简单 PHP 邮件函数

 $to      = $email_id;
 $subject = "Test Subject";
 $message = "Your mail Body Content. you also use here HTML Tags for better UI. ";
 $headers = 'From: xyz@domainname.com' . "\r\n" .
  'Reply-To: xyz@domainname.com' . "\r\n" .
  'X-Mailer: PHP/' . phpversion();
 $headers.= "MIME-Version: 1.0" . "\r\n";
 $headers.= "Content-type:text/html;charset=UTF-8" . "\r\n";

 $test=mail($to, $subject, $message, $headers);

或下载 PHPMailer 库并参考以下示例

ini_set('SMTP', "smtp.gmail.com"); // Your domain SMTP
ini_set('smtp_port', "465"); // here we write your domain SMTP port
ini_set('sendmail_from', "xxxx@domain.com"); // your email make sure email id is available on above mention SMTP 
ini_Set('password',"xxxxxx"); // email account password


require 'C:\xampp\htdocs\demo\PHPMailer_5.2.4\class.phpmailer.php'; //load phpmailer library here

$mail = new PHPMailer;
$mail->IsSMTP();         // send via SMTP
//IsSMTP();             // send via SMTP
$mail->SMTPAuth = true;  // turn on SMTP authentication
$mail->Host="smtp.gmail.com";
$mail->Mailer="smtp"; // domain SMTP
$mail->port=465; // Domain mail port
$mail->Username = "abc@gmail.com";   // SMTP username
$mail->Password = "xxxxx";      // SMTP password

$webmaster_email = "abc@gmail.com";     //Reply to this email ID
$email="abc@test.com";                 // Recipients email ID
$name="Test mail";             // Recipient's name
$mail->From = $webmaster_email;
$mail->FromName = "Test Name";
$mail->AddAddress($email,$name);
$mail->AddReplyTo($webmaster_email,"Webmaster");
$mail->WordWrap = 50; // set word wrap
$mail->AddAttachment("/var/tmp/file.tar.gz");        // attachment
$mail->AddAttachment("/tmp/image.jpg", "new.jpg");   // attachment
$mail->IsHTML(true); // send as HTML
$mail->Subject = "Thanks For Connecting";
$mail->Body = "This is your mail body"; //HTML Body
$mail->AltBody = "This is the body when user views in plain text format";     //Text Body
if(!$mail->Send())
{
    echo "Mailer Error: " . $mail->ErrorInfo;
}
else
{
    echo "Message has been sent";
}
