要在 PHP 中发送电子邮件，您可以使用 PHPMailer 或 SwiftMailer 等第三方库，也可以使用 PHP 内置的 mail() 函数。下面是用PHPMailer发送实例。
一、安装PHPMailer
composer require phpmailer/phpmailer
二、发送邮件
<?php
namespace app\admin\service;
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;
class MailService
{
/**
* @param $to
* @param string $subject
* @param string $content
* @param string $addAttachment
* @return array
* @throws Exception
* @author: LuckyHhy <jackhhy520@qq.com>
* @describe:发送邮件
*/
public static function sendEmail($to,$subject='',$content='',$addAttachment=''){
//判断openssl是否开启
$openssl_funcs = get_extension_funcs('openssl');
if(!$openssl_funcs){
return ['code'=>0 , 'msg'=>'请先开启openssl扩展'];
}
$config=sysconfig("mail");
$mail = new PHPMailer;
$mail->CharSet = 'UTF-8'; //设定邮件编码，默认ISO-8859-1，如果发中文此项必须设置，否则乱码
$mail->isSMTP();
$mail->SMTPDebug = 0;
//Whether to use SMTP authentication
$mail->SMTPAuth = true;
//调试输出格式
$mail->Debugoutput = 'html';
//smtp服务器
$mail->Host = $config['mail_smtp_host'];
//端口 - likely to be 25, 465 or 587
$mail->Port = $config['mail_smtp_port'];
$mail->SMTPSecure =$config['mail_secure'];// 使用安全协议 tls,ssl
//用户名
$mail->Username = $config['mail_smtp_user'];
//密码
$mail->Password = $config['mail_smtp_pass'];
//Set who the message is to be sent from
$mail->setFrom($config['mail_smtp_user'],$config['mail_smtp_name']);
//回复地址
//$mail->addReplyTo('replyto@example.com', 'First Last');
//接收邮件方
if(is_array($to)){
foreach ($to as $v){
$mail->addAddress($v);
}
}else{
$mail->addAddress($to);
}
$mail->isHTML(true);// send as HTML
//标题
$mail->Subject = $subject;
//邮箱正文
$mail->Body = $content;
//添加附件
if (!empty($addAttachment)){
$mail->addAttachment($addAttachment);
}
try {
$mail->send();
return ['code'=>1 , 'msg'=>'发送成功'];
}catch (Exception $e){
return ['code'=>0 , 'msg'=>$e->getMessage()];
}
}
}
