通過PHP發送郵件！

今天學習了下通過PHP發送郵件的方法，具體代碼如下：

 

<?php /** * 發送郵件類 * 調用方法： * require_once 'mail.class.php'; // 設置郵件編碼格式 define('CHARSET', 'utf-8'); $sendmail = new sendmail(); // 設置參數 $sendmail->set('11', '11', '11', '11'); $issend = $sendmail->send("[e-mail]", "歡迎測試郵件！", "郵件測試！", "[e-mail]"); if($issend) echo "發送成功！"; else echo "發送失敗！"; * */ class sendmail { function sendmail() { // 設置發郵件參數：郵件服務器，端口，發信人郵件帳號，發信人密碼 $this->set('mail_server', 'mail_port', 'mail_user', 'mail_password'); $this->auth = 1; } function set($server, $port, $user, $password, $type = 1, $delimiter = 1, $mailusername = 0) { $this->type = $type; $this->server = $server; $this->port = $port; $this->user = $user; $this->password = $password; $this->delimiter = $delimiter == 1 ? "/r/n" : ($delimiter == 2 ? "/r" : "/n"); $this->mailusername = $mailusername; } function send($email_to, $email_subject, $email_message, $email_from = '') { $email_subject = '=?'.CHARSET.'?B?'.base64_encode(str_replace("/r", '', $email_subject)).'?='; $email_message = str_replace("/r/n.", " /r/n..", str_replace("/n", "/r/n", str_replace("/r", "/n", str_replace("/r/n", "/n", str_replace("/n/r", "/r", $email_message))))); $adminemail = $this->type == 1 ?
