本文介绍下,一个用于email邮件发送的类,可以使用smtp与mail函数二种方式发送邮件,有需要的朋友参考下。

php实现的邮件发送类,二种方式: smtp方式与mail函数方式。

代码:

调用示例:

SendMailVia = 'smtp';  // Send via smtp server or mail function 
$Mail->smtp_host = 'mail.myhost.com'; 
$Mail->smtp_port = 25; 
$Mail->smtp_user = 'user@myhost.com'; 
$Mail->smtp_password = 'mypassw'; 

// 例1 (mail from me) 
if($Mail->Send('mymail1@mydomain.com; recipient2 name ,"recipient name" ',
'My subject','My message here.')) 
{ 
  echo '邮件已发送!'; 
} 
else 
{ 
  echo $Mail->error; 
} 

// 例2 (mail from me) 
$Mail->mail_to = 'mymail1@mydomain.com; recipient2 name ,"recipient name" '; 
$Mail->subject = 'My subject'; 
$Mail->message = 'My message here'; 

if($Mail->Send()) 
{ 
  echo '邮件已发送!'; 
} 
else 
{ 
  echo $Mail->error; 
} 


// 例3 (mail from another user: example user2@site2.com) 

$Mail->mail_to = 'Recipient Name '; 
$Mail->subject = 'My subject'; 
$Mail->message = 'My message here'; 
$Mail->from_name = 'User2 Name'; 
$Mail->SendFromMail = 'user2@site2.com'; 

if($Mail->Send()) 
{ 
  echo 'message Mail send!'; 
} 
else 
{ 
  echo $Mail->error; 
} 

?>
