php smtp發送郵件
php通過smtp發送郵件需要通過一個類smtp
發郵件的代碼如下：
require_once 'smtp.php';#
$smtpserver = "smtp.sina.com";//SMTP服務器 $smtpserverport = 25;//SMTP服務器端口 $smtpusermail = "god_chen@sina.com";//SMTP服務器的用戶郵箱 $smtpemailto = "45323333@qq.com";//發送給誰 $smtpuser = "name";//SMTP服務器的用戶帳號 $smtppass = "123456";//SMTP服務器的用戶密碼 $mailsubject = "中文";//郵件主題 $mailbody = "<h1>中文</h1>測試下能淤泥新年感";//郵件內容 $mailtype = "HTML";//郵件格式（HTML/TXT）,TXT為文本郵件
#
$smtp = new smtp($smtpserver,$smtpserverport,true,$smtpuser,$smtppass);//這里面的一個true是表示使用身份驗證,否則不使用身份驗證. $smtp->debug = FALSE;//是否顯示發送的調試信息 $smtp->sendmail($smtpemailto, $smtpusermail, $mailsubject, $mailbody, $mailtype)</pre>
smtp類的源碼如下：
